[0001] This application is a continuation of application Ser. No. 10/355,543 filed Jan. 31, 2003, now pending, which claims benefit under 35 U.S.C. § 119(e) to application Ser. No. 60/353,333 filed Feb. 1, 2002; application Ser. No. 60/353,267 filed Feb. 1, 2002; application Ser. No. 60/399,673 filed Jul. 29, 2002; and application Ser. No. 60/434,277 filed Dec. 17, 2002. The contents of application Ser. No. 10/355,543 are incorporated herein by reference.

[0002] The present invention relates generally to 2,4-pyrimidinediamine compounds, pharmaceutical compositions comprising the compounds, intermediates and synthetic methods of making the compounds and methods of using the compounds and compositions in a variety of contexts.

[0003] Crosslinking of Fc receptors, such as the high affinity receptor for IgE (FcεRI) and/or the high affinity receptor for IgG (FcγRI) activates a signaling cascade in mast, basophil and other immune cells that results in the release of chemical mediators responsible for numerous adverse events. For example, such crosslinking leads to the release of preformed mediators of Type I (immediate) anaphylactic hypersensitivity reactions, such as histamine, from storage sites in granules via degranulation. It also leads to the synthesis and release of other mediators, including leukotrienes, prostaglandins and platelet-activating factors (PAFs), that play important roles in inflammatory reactions. Additional mediators that are synthesized and released upon crosslinking Fc receptors include cytokines and nitric oxide.

[0004] The signaling cascade(s) activated by crosslinking Fc receptors such as FcεRI and/or FcγRI comprises an array of cellular proteins. Among the most important intracellular signal propagators are the tyrosine kinases. And, an important tyrosine kinase involved in the signal transduction pathways associated with crosslinking the FcεRI and/or FcγRI receptors, as well as other signal transduction cascades, is Syk kinase (see Valent et al., 2002, Intl. J. Hematol. 75(4):257–362 for review).

[0005] As the mediators released as a result of FcεRI and FcγRI receptor cross-linking are responsible for, or play important roles in, the manifestation of numerous adverse events, the availability of compounds capable of inhibiting the signaling cascade(s) responsible for their release would be highly desireable. Moreover, owing to the critical role that Syk kinase plays these and other receptor signaling cascade(s), the availability of compounds capable of inhibiting Syk kinase would also be highly desirable.

[0006] In one aspect, the present invention provides novel 2,4-pyrimidinediamine compounds that, as will be discussed in more detail below, have myriad biological activities. The compounds generally comprise a 2,4-pyrimidinediamine “core” having the following structure and numbering convention:

[0007]

[0008] The compounds of the invention are substituted at the C2 nitrogen (N2) to form a secondary amine and are optionally further substituted at one or more of the following positions: the C4 nitrogen (N4), the C5 position and/or the C6 position. When substituted at N4, the substituent forms a secondary amine. The substituent at N2, as well as the optional substituents at the other positions, may range broadly in character and physico-chemical properties. For example, the substituent(s) may be a branched, straight-chained or cyclic alkyl, a branched, straight-chained or cyclic heteroalkyl, a mono- or polycyclic aryl a mono- or polycyclic heteroaryl or combinations of these groups. These substituent groups may be further substituted, as will be described in more detail below.

[0009] The N2 and/or N4 substituents may be attached directly to their respective nitrogen atoms, or they may be spaced away from their respective nitrogen atoms via linkers, which may be the same or different. The nature of the linkers can vary widely, and can include virtually any combination of atoms or groups useful for spacing one molecular moiety from another. For example, the linker may be an acyclic hydrocarbon bridge (e.g, a saturated or unsaturated alkyleno such as methano, ethano, etheno, propano, prop[1]eno, butano, but[1]eno, but[2]eno, buta[1,3]dieno, and the like), a monocyclic or polycyclic hydrocarbon bridge (e.g., [1,2]benzeno, [2,3]naphthaleno, and the like), a simple acyclic heteroatomic or heteroalkyldiyl bridge (e.g., —O—, —S—, —S—O—, —NH—, —PH—, —C(O)—, —C(O)NH—, —S(O)—, —S(O)₂—, —S(O)NH—, —S(O)₂NH—, —O—CH₂—, —CH₂—O—CH₂—, —O—CH═CH—CH₂—, and the like), a monocyclic or polycyclic heteroaryl bridge (e.g., [3,4]furano, pyridino, thiopheno, piperidino, piperazino, pyrazidino, pyrrolidino, and the like) or combinations of such bridges.

[0010] The substituents at the N2, N4, C5 and/or C6 positions, as well as the optional linkers, may be further substituted with one or more of the same or different substituent groups. The nature of these substituent groups may vary broadly. Non-limiting examples of suitable substituent groups include branched, straight-chain or cyclic alkyls, mono- or polycyclic aryls, branched, straight-chain or cyclic heteroalkyls, mono- or polycyclic heteroaryls, halos, branched, straight-chain or cyclic haloalkyls, hydroxyls, oxos, thioxos, branched, straight-chain or cyclic alkoxys, branched, straight-chain or cyclic haloalkoxys, trifluoromethoxys, mono- or polycyclic aryloxys, mono- or polycyclic heteroaryloxys, ethers, alcohols, sulfides, thioethers, sulfanyls (thiols), imines, azos, azides, amines (primary, secondary and tertiary), nitriles (any isomer), cyanates (any isomer), thiocyanates (any isomer), nitrosos, nitros, diazos, sulfoxides, sulfonyls, sulfonic acids, sulfamides, sulfonamides, sulfamic esters, aldehydes, ketones, carboxylic acids, esters, amides, amidines, formadines, amino acids, acetylenes, carbamates, lactones, lactams, glucosides, gluconurides, sulfones, ketals, acetals, thioketals, oximes, oxamic acids, oxamic esters, etc., and combinations of these groups. Substituent groups bearing reactive functionalities may be protected or unprotected, as is well-known in the art.

[0020] each R^a is independently selected from the group consisting of hydrogen, (C1–C6) alkyl, (C3–C8) cycloalkyl, cyclohexyl, (C4–C11) cycloalkylalkyl, (C5–C10) aryl, phenyl, (C6–C16) arylalkyl, benzyl, 2–6 membered heteroalkyl, 3–8 membered cycloheteroalkyl, morpholinyl, piperazinyl, homopiperazinyl, piperidinyl, 4–11 membered cycloheteroalkylalkyl, 5–10 membered heteroaryl and 6–16 membered heteroarylalkyl;

[0022] each R^c is independently a protecting group or R^a, or, alternatively, each R^c is taken together with the nitrogen atom to which it is bonded to form a 5 to 8-membered cycloheteroalkyl or heteroaryl which may optionally include one or more of the same or different additional heteroatoms and which may optionally be substituted with one or more of the same or different R^a or suitable R^b groups;

[0023] each R^d is independently a protecting group or R^a;

[0024] each m is independently an integer from 1 to 3; and

[0025] each n is independently an integer from 0 to 3.

[0026] In another aspect, the present invention provides prodrugs of the 2,4-pyrimidinediamine compounds. Such prodrugs may be active in their prodrug form, or may be inactive until converted under physiological or other conditions of use to an active drug form. In the prodrugs of the invention, one or more functional groups of the 2,4-pyrimidinediamine compounds are included in promoieties that cleave from the molecule under the conditions of use, typically by way of hydrolysis, enzymatic cleavage or some other cleavage mechanism, to yield the functional groups. For example, primary or secondary amino groups may be included in an amide promoiety that cleaves under conditions of use to generate the primary or secondary amino group. Thus, the prodrugs of the invention include special types of protecting groups, termed “progroups,” masking one or more functional groups of the 2,4-pyrimidinediamine compounds that cleave under the conditions of use to yield an active 2,4-pyrimidinediamine drug compound. Functional groups within the 2,4-pyrimidinediamine compounds that may be masked with progroups for inclusion in a promoiety include, but are not limited to, amines (primary and secondary), hydroxyls, sulfanyls (thiols), carboxyls, carbonyls, phenols, catechols, diols, alkynes, phosphates, etc. Myriad progroups suitable for masking such functional groups to yield promoieties that are cleavable under the desired conditions of use are known in the art. All of these progroups, alone or in combinations, may be included in the prodrugs of the invention. Specific examples of promoieties that yield primary or secondary amine groups that can be included in the prodrugs of the invention include, but are not limited to amides, carbamates, imines, ureas, phosphenyls, phosphoryls and sulfenyls. Specific examples of promoieties that yield sulfanyl groups that can be included in the prodrugs of the invention include, but are not limited to, thioethers, for example S-methyl derivatives (monothio, dithio, oxythio, aminothio acetals), silyl thioethers, thioesters, thiocarbonates, thiocarbamates, asymmetrical disulfides, etc. Specific examples of promoieties that cleave to yield hydroxyl groups that can be included in the prodrugs of the invention include, but are not limited to, sulfonates, esters and carbonates. Specific examples of promoieties that yield carboxyl groups that can be included in the prodrugs of the invention included, but are not limited to, esters (including silyl esters, oxamic acid esters and thioesters), amides and hydrazides.

[0027] In one illustrative embodiment, the prodrugs of the invention are compounds according to structural formula (I) in which the protecting group of R^c and R^d is a progroup.

[0028] Replacing the hydrogens attached to N2 and N4 in the 2,4-pyrimidinediamines of structural formula (I) with substituents adversely affects the activity of the compounds. However, as will be appreciated by skilled artisans, these nitrogens may be included in promoieties that, under conditions of use, cleave to yield 2,4-pyrimidinediamines according to structural formula (I). Thus, in another illustrative embodiment, the prodrugs of the invention are compounds according to structural formula (II):

[0029]

[0030] including salts, hydrates, solvates and N-oxides thereof, wherein:

[0031] R², R⁴, R⁵, R⁶, L¹ and L² are as previously defined for structural formula (I); and

[0032] R^2b and R^4b are each, independently of one another, a progroup.

[0033] In another aspect, the present invention provides compositions comprising one or more compounds and/or prodrugs of the invention and an appropriate carrier, excipient or diluent. The exact nature of the carrier, excipient or diluent will depend upon the desired use for the composition, and may range from being suitable or acceptable for veterinary uses to being suitable or acceptable for human use.

[0034] In still another aspect, the present invention provides intermediates useful for synthesizing the 2,4-pyrimidinediamine compounds and prodrugs of the invention. In one embodiment, the intermediates are 4-pyrimidineamines according to structural formula (III):

[0035]

[0036] including salts, hydrates, solvates and N-oxides thereof, wherein R⁴, R⁵, R⁶ and L² are as previously defined for structural formula (I); LG is a leaving group such as, for example, —S(O)₂Me, —SMe or halo (e.g., F, Cl, Br, I); and R^4c is hydrogen or a progroup.

[0037] In another embodiment, the intermediates are 2-pyrimidineamines according to structural formula (IV):

[0038]

[0039] including salts, hydrates, solvates and N-oxides thereof, wherein R², R⁵, R⁶ and L¹ are as previously defined for structural formula (I); LG is a leaving group, such as, for example, —S(O)₂Me, —SMe or halo (e.g., F, Cl, Br, I) and R^2c is hydrogen or a progroup.

[0040] In yet another embodiment, the intermediates are 4-amino- or 4-hydroxy-2-pyrimidineamines according to structural formula (V):

[0041]

[0042] including salts, hydrates, solvates and N-oxides thereof, wherein R², R⁵, R⁶ and L¹ are as previously defined for structural formula (I), R⁷ is an amino or hydroxyl group and R^2c is hydrogen or a progroup.

[0043] In another embodiment, the intermediates are N4-substituted cytosines according to structural formula (VI):

[0044]

[0045] including salts, hydrates, solvates and N-oxides thereof, wherein R⁴, R⁵, R⁶ and L² are as previously defined for structural formula (I) and R^4c is hydrogen or a progroup.

[0046] In yet another aspect, the present invention provides methods of synthesizing the 2,4-pyrimidinediamine compounds and prodrugs of the invention. In one embodiment, the method involves reacting a 4-pyrimidineamine according to structural formula (III) with an amine of the formula HR^2cN—L¹—R², where L¹, R² and R^2c are as previously defined for structural formula (IV) to yield a 2,4-pyrimidinediamine according to structural formula (I) or a prodrug according to structural formula (II).

[0047] In another embodiment, the method involves reacting a 2-pyrimidineamine according to structural formula (IV) with an amine of the formula R⁴—L²—NHR^4c where L⁴, R⁴ and R^4c are as previously defined for structural formula (III) to yield a 2,4-pyrimidinediamine according to structural formula (I) or a prodrug according to structural formula (II).

[0048] In yet another embodiment, the method involves reacting a 4-amino-2-pyrimidineamine according to structural formula (V) (in which R⁷ is an amino group) with an amine of the formula R⁴—L²—NHR^4c, where L², R⁴ and R^4c are as defined for structural formula (III), to yield a 2,4-pyrimidinediamine according to structural formula (I) or a prodrug according to structural formula (II). Alternatively, the 4-amino-2-pyrimidineamine may be reacted with a compound of the formula R⁴—L²—LG, where R⁴ and L² are as previously defined for structural formula (I) and LG is a leaving group.

[0049] In still another embodiment, the method involves halogenating a 4-hydroxy-2-pyrimidineamine according to structural formula (V) (R⁷ is a hydroxyl group) to yield a 2-pyrimidineamine according to structural formula (IV) and reacting this pyrimidineamine with an appropriate amine, as described above.

[0050] In yet another embodiment, the method involves halogenating an N4-substituted cytosine according to structural formula (VI) to yield a 4-pyrimidineamine according to structural formula (III) and reacting this pyrimidineamine with an appropriate amine, as described above.

[0051] The 2,4-pyrimidinediamine compounds of the invention are potent inhibitors of degranulation of immune cells, such as mast, basophil, neutrophil and/or eosinophil cells. Thus, in still another aspect, the present invention provides methods of regulating, and in particular inhibiting, degranulation of such cells. The method generally involves contacting a cell that degranulates with an amount of a 2,4-pyrimidinediamine compound or prodrug of the invention, or an acceptable salt, hydrate, solvate, N-oxide and/or composition thereof, effective to regulate or inhibit degranulation of the cell. The method may be practiced in in vitro contexts or in in vivo contexts as a therapeutic approach towards the treatment or prevention of diseases characterized by, caused by or associated with cellular degranulation.

[0052] While not intending to be bound by any theory of operation, biochemical data confirm that the 2,4-pyrimidinediamine compounds exert their degranulation inhibitory effect, at least in part, by blocking or inhibiting the signal transduction cascade(s) initiated by crosslinking of the high affinity Fc receptors for IgE (“FcεRI”) and/or IgG (“FcγRI”). Indeed, the 2,4-pyrimidinediamine compounds are potent inhibitors of both FcεRI-mediated and FcγRI-mediated degranulation. As a consequence, the 2,4-pyrimidine compounds may be used to inhibit these Fc receptor signalling cascades in any cell type expressing such FcεRI and/or FcγRI receptors including but not limited to macrophages, mast, basophil, neutrophil and/or eosinophil cells.

[0053] The methods also permit the regulation of, and in particular the inhibition of, downstream processes that result as a consequence of activating such Fc receptor signaling cascade(s). Such downstream processes include, but are not limited to, FcεRI-mediated and/or FcγRI-mediated degranulation, cytokine production and/or the production and/or release of lipid mediators such as leukotrienes and prostaglandins. The method generally involves contacting a cell expressing an Fc receptor, such as one of the cell types discussed above, with an amount of a 2,4-pyrimidinediamine compound or prodrug of the invention, or an acceptable salt, hydrate, solvent, N-oxide and/or composition thereof, effective to regulate or inhibit the Fc receptor signaling cascade and/or a downstream process effected by the activation of this signaling cascade. The method may be practiced in in vitro contexts or in in vivo contexts as a therapeutic approach towards the treatment or prevention of diseases characterized by, caused by or associated with the Fc receptor signaling cascade, such as diseases effected by the release of granule specific chemical mediators upon degranulation, the release and/or synthesis of cytokines and/or the release and/or synthesis of lipid mediators such as leukotrienes and prostaglandins.

[0054] In yet another aspect, the present invention provides methods of treating and/or preventing diseases characterized by, caused by or associated with the release of chemical mediators as a consequence of activating Fc receptor signaling cascades, such as FcεRI and/or FcγRI-signaling cascades. The methods may be practiced in animals in veterinary contexts or in humans. The methods generally involve administering to an animal subject or human an amount of a 2,4-pyrimidinediamine compound or prodrug of the invention, or an acceptable salt, hydrate, solvate, N-oxide and/or composition thereof, effective to treat or prevent the disease. As discussed previously, activation of the FcεRI or FcγRI receptor signaling cascade in certain immune cells leads to the release and/or synthesis of a variety of chemical substances that are pharmacological mediators of a wide variety of diseases. Any of these diseases may be treated or prevented according to the methods of the invention.

[0055] For example, in mast cells and basophil cells, activation of the FcεRI or FcγRI signaling cascade leads to the immediate (i.e., within 1–3 min. of receptor activation) release of preformed mediators of atopic and/or Type I hypersensitivity reactions (e.g., histamine, proteases such as tryptase, etc.) via the degranulation process. Such atopic or Type I hypersensitivity reactions include, but are not limited to, anaphylactic reactions to environmental and other allergens (e.g., pollens, insect and/or animal venoms, foods, drugs, contrast dyes, etc.), anaphylactoid reactions, hay fever, allergic conjunctivitis, allergic rhinitis, allergic asthma, atopic dermatitis, eczema, urticaria, mucosal disorders, tissue disorders and certain gastrointestinal disorders.

[0056] The immediate release of the preformed mediators via degranulation is followed by the release and/or synthesis of a variety of other chemical mediators, including, among other things, platelet activating factor (PAF), prostaglandins and leukotrienes (e.g., LTC4) and the de novo synthesis and release of cytokines such as TNFα, IL4, IL-5, IL-6, IL-13, etc. The first of these two processes occurs approximately 3–30 min. following receptor activation; the latter approximately 30 min.–7 hrs. following receptor activation. These “late stage” mediators are thought to be in part responsible for the chronic symptoms of the above-listed atopic and Type I hypersensitivity reactions, and in addition are chemical mediators of inflammation and inflammatory diseases (e.g., osteoarthritis, inflammatory bowel disease, ulcerative colitis, Crohn's disease, idiopathic inflammatory bowel disease, irritable bowel syndrome, spastic colon, etc.), low grade scarring (e.g., scleroderma, increased fibrosis, keloids, post-surgical scars, pulmonary fibrosis, vascular spasms, migraine, reperfusion injury and post myocardial infarction), and sicca complex or syndrome. All of these diseases may be treated or prevented according to the methods of the invention.

[0057] Additional diseases which can be treated or prevented according to the methods of the invention include diseases associated with basophil cell and/or mast cell pathology. Examples of such diseases include, but are not limited to, diseases of the skin such as scleroderma, cardiac diseases such as post myocardial infarction, pulmonary diseases such as pulmonary muscle changes or remodeling and chronic obstructive pulmonary disease (COPD) and diseases of the gut such as inflammatory bowel syndrome (spastic colon).

[0058] The 2,4-pyrimidinediamine compounds of the invention are also potent inhibitors of the tyrosine kinase Syk kinase. Thus, in still another aspect, the present invention provides methods of regulating, and in particular inhibiting, Syk kinase activity. The method generally involves contacting a Syk kinase or a cell comprising a Syk kinase with an amount of a 2,4-pyrimidinediamine compound or prodrug of the invention, or an acceptable salt, hydrate, solvate, N-oxide and/or composition thereof, effective to regulate or inhibit Syk kinase activity. In one embodiment, the Syk kinase is an isolated or recombinant Syk kinase. In another embodiment, the Syk kinase is an endogenous or recombinant Syk kinase expressed by a cell, for example a mast cell or a basophil cell. The method may be practiced in in vitro contexts or in in vivo contexts as a therapeutic approach towards the treatment or prevention of diseases characterized by, caused by or associated with Syk kinase activity.

[0059] While not intending to be bound by any particular theory of operation, it is believed that the 2,4-pyrimdinediamine compounds of the invention inhibit cellular degranulation and/or the release of other chemical mediators primarily by inhibiting Syk kinase that gets activated through the gamma chain homodimer of FcεRI (see, e.g., FIG. 2). This gamma chain homodimer is shared by other Fc receptors, including FcγRI, FcγRIII and FcαRI. For all of these receptors, intracellular signal transduction is mediated by the common gamma chain homodimer. Binding and aggregation of those receptors results in the recruitment and activation of tyrosine kinases such as Syk kinase. As a consequence of these common signaling activities, the 2,4-pyrimidinediamine compounds described herein may be used to regulate, and in particular inhibit, the signaling cascades of Fc receptors having this gamma chain homodimer, such as FcεRI, FcγRI, FcγRIII and FcαRI, as well as the cellular responses elicited through these receptors.

[0060] Syk kinase is known to play a critical role in other signaling cascades. For example, Syk kinase is an effector of B-cell receptor (BCR) signaling (Turner et al., 2000, Immunology Today 21:148–154) and is an essential component of integrin beta(1), beta(2) and beta(3) signaling in neutrophils (Mocsai et al., 2002, Immunity 16:547–558). As the 2,4-pyrimidinediamine compounds described herein are potent inhibitors of Syk kinase, they can be used to regulate, and in particular inhibit, any signaling cascade where Syk plays a role, such as, fore example, the Fc receptor, BCR and integrin signaling cascades, as well as the cellular responses elicited through these signaling cascades. The particular cellular response regulated or inhibited will depend, in part, on the specific cell type and receptor signaling cascade, as is well known in the art. Non-limiting examples of cellular responses that may be regulated or inhibited with the 2,4-pyrimidinediamine compounds include a respiratory burst, cellular adhesion, cellular degranulation, cell spreading, cell migration, phagocytosis (e.g., in macrophages), calcium ion flux (e.g., in mast, basophil, neutrophil, eosinophil and B-cells), platelet aggregation, and cell maturation (e.g., in B-cells).

[0061] Thus, in another aspect, the present invention provides methods of regulating, and in particular inhibiting, signal transduction cascades in which Syk plays a role. The method generally involves contacting a Syk-dependent receptor or a cell expressing a Syk-dependent receptor with an amount of a 2,4-pyrimidinediamine compound or prodrug of the invention, or an acceptable salt, hydrate, solvate, N-oxide and/or composition thereof, effective to regulate or inhibit the signal transduction cascade. The methods may also be used to regulate, and in particular inhibit, downstream processes or cellular responses elicited by activation of the particular Syk-dependent signal transduction cascade. The methods may be practiced to regulate any signal trasduction cascade where Syk is not known or later discovered to play a role. The methods may be practiced in in vitro contexts or in in vivo contexts as a therapeutic approach towards the treatment or prevention of diseases characterized by, caused by or associated with activation of the Syk-dependent signal transduction cascade. Non-limited examples of such diseases include those previously discussed.

[0095] “Haloalkyl” by itself or as part of another substituent refers to an alkyl group in which one or more of the hydrogen atoms is replaced with a halogen.

As another example, “haloalkoxy” or “haloalkyloxy” refers to a group of the formula —OR′″, where R′″ is a haloalkyl.

[0097] “Protecting group” refers to a group of atoms that, when attached to a reactive functional group in a molecule, mask, reduce or prevent the reactivity of the functional group. Typically, a protecting group may be selectively removed as desired during the course of a synthesis. Examples of protecting groups can be found in Greene and Wuts, Protective Groups in Organic Chemistry, 3rd Ed., 1999, John Wiley & Sons, NY and Harrison et al., Compendium of Synthetic Organic Methods, Vols. 1–8, 1971–1996, John Wiley & Sons, NY. Representative amino protecting groups include, but are not limited to, formyl, acetyl, trifluoroacetyl, benzyl, benzyloxycarbonyl (“CBZ”), tert-butoxycarbonyl (“Boc”), trimethylsilyl (“TMS”), 2-trimethylsilyl-ethanesulfonyl (“TES”), trityl and substituted trityl groups, allyloxycarbonyl, 9-fluorenylmethyloxycarbonyl (“FMOC”), nitro-veratryloxycarbonyl (“NVOC”) and the like. Representative hydroxyl protecting groups include, but are not limited to, those where the hydroxyl group is either acylated or alkylated such as benzyl and trityl ethers, as well as alkyl ethers, tetrahydropyranyl ethers, trialkylsilyl ethers (e.g., TMS or TIPPS groups) and allyl ethers.

[0098] “Prodrug” refers to a derivative of an active 2,4-pyrimidinediamine compound (drug) that requires a transformation under the conditions of use, such as within the body, to release the active 2,4-pyrimidinediamine drug. Prodrugs are frequently, but not necessarily, pharmacologically inactive until converted into the active drug. Prodrugs are typically obtained by masking a functional group in the 2,4-pyrimidinediamine drug believed to be in part required for activity with a progroup (defined below) to form a promoiety which undergoes a transformation, such as cleavage, under the specified conditions of use to release the functional group, and hence the active 2,4-pyrimidinediamine drug. The cleavage of the promoiety may proceed spontaneously, such as by way of a hydrolysis reaction, or it may be catalyzed or induced by another agent, such as by an enzyme, by light, by acid or base, or by a change of or exposure to a physical or environmental parameter, such as a change of temperature. The agent may be endogenous to the conditions of use, such as an enzyme present in the cells to which the prodrug is administered or the acidic conditions of the stomach, or it may be supplied exogenously.

[0099] A wide variety of progroups, as well as the resultant promoieties, suitable for masking functional groups in the active 2,4-pyrimidinediamines compounds to yield prodrugs are well-known in the art. For example, a hydroxyl functional group may be masked as a sulfonate, ester or carbonate promoiety, which may be hydrolyzed in vivo to provide the hydroxyl group. An amino functional group may be masked as an amide, carbamate, imine, urea, phosphenyl, phosphoryl or sulfenyl promoiety, which may be hydrolyzed in vivo to provide the amino group. A carboxyl group may be masked as an ester (including silyl esters and thioesters), amide or hydrazide promoiety, which may be hydrolyzed in vivo to provide the carboxyl group. Other specific examples of suitable progroups and their respective promoieties will be apparent to those of skill in the art.

[0100] “Progroup” refers to a type of protecting group that, when used to mask a functional group within an active 2,4-pyrimidinediamine drug to form a promoiety, converts the drug into a prodrug. Progroups are typically attached to the functional group of the drug via bonds that are cleavable under specified conditions of use. Thus, a progroup is that portion of a promoiety that cleaves to release the functional group under the specified conditions of use. As a specific example, an amide promoiety of the formula —NH—C(O)CH₃ comprises the progroup —C(O)CH₃.

[0101] “Fc Receptor” refers to a member of the family of cell surface molecules that binds the Fc portion (containing the specific constant region) of an immunoglobulin. Each Fc receptor binds immunoglobulins of a specific type. For example the Fcα receptor (“FcαR”) binds IgA, the FcεR binds IgE and the FcγR binds IgG.

[0102] The FcαR family includes the polymeric Ig receptor involved in epithelial transport of IgA/IgM, the mycloid specific receptor RcαRI (also called CD89), the Fcα/μR and at least two alternative IgA receptors (for a recent review see Monteiro & van de Winkel, 2003, Annu. Rev. Immunol, advanced e-publication. The FcαRI is expressed on neutrophils, eosinophils, moncytes/macrophages, dendritic cells and kupfer cells. The FcαRI inclues one alpha chain and the FcR gamma homodimer that bears an activation motif (ITAM) in the cytoplasmic domain and phosphorylates Syk kinase.

[0103] The FcεR family includes two types, designated FcεRI and FcεRII (also known as CD23). FcεRI is a high affinity receptor (binds IgE with an affinity of about 10¹⁰M⁻¹) found on mast, basophil and eosinophil cells that anchors monomeric IgE to the cell surface. The FcεRI possesses one alpha chain, one beta chain and the gamma chain homodimer discussed above. The FcεRII is a low affinity receptor expressed on mononuclear phagocytes, B lymphocytes, eosinophils and platelets. The FcεRII comprises a single polypeptide chain and does not include the gamma chain homodimer.

[0104] The FcγR family includes three types, designated FcγRI (also known as CD64), FcγRII (also known as CD32) and FcγRIII (also known as CD16). FcγRI is a high affinity receptor (binds IgG1 with an affinity of 10⁸M⁻¹) found on mast, basophil, mononuclear, neutrophil, eosinophil, deudritic and phagocyte cells that anchors nomomeric IgG to the cell surface. The FcγRI includes one alpha chain and the gamma chain dimer shared by FcαRI and FcεRI.

[0105] The FcγRII is a low affinity receptor expressed on neutrophils, monocytes, eosinophils, platelets and B lymphocytes. The FcγRII includes one alpha chain, and does not include the gamma chain homodimer discussed above.

[0106] The FcγRIII is a low affinity (bindes IgG1 with an affinity of 5×10⁵M⁻¹) expressed on NK, eosinophil, macrophage, neutrophil and mast cells. It comprises one alpha chain and the gamma homodimer shared by FcαRI, FcεRI and FcγRI.

[0107] Skilled artisans will recognize that the subunit structure and binding properties of these various Fc receptors, cell types expressing them, are not completely characterized. The above discussion merely reflects the current state-of-the-art regarding these receptors (see, e.g., Immunobiology: The Immune System in Health & Disease, 5^th Edition, Janeway et al., Eds, 2001, ISBN 0-8153-3642-x, FIG. 9.30 at pp. 371), and is not intended to be limiting with respect to the myriad receptor signaling cascades that can be regulated with the compounds described herein.

[0108] “Fc Receptor-Mediated Degranulation” or “Fc Receptor-Induced Degranulation” refers to degranulation that proceeds via an Fc receptor signal transduction cascade initiated by crosslinking of an Fc receptor.

[0109] “IgE-Induced Degranulation” or “FcεRI-Mediated Degranulation” refers to degranulation that proceeds via the IgE receptor signal transduction cascade initiated by crosslinking of FcεR1-bound IgE. The crosslinking may be induced by an IgE-specific allergen or other multivalent binding agent, such as an anti-IgE antibody. Referring to FIG. 2, in mast and/or basophil cells, the FcεRI signaling cascade leading to degranulation may be broken into two stages: upstream and downstream. The upstream stage includes all of the processes that occur prior to calcium ion mobilization (illustrated as “Ca²⁺” in FIG. 2; see also FIG. 3). The downstream stage includes calcium ion mobilization and all processes downstream thereof. Compounds that inhibit FcεRI-mediated degranulation may act at any point along the FcεRI-mediated signal transduction cascade. Compounds that selectively inhibit upstream FcεRI-mediated degranulation act to inhibit that portion of the FcεRI signaling cascade upstream of the point at which calcium ion mobilization is induced. In cell-based assays, compounds that selectively inhibit upstream FcεRI-mediated degranulation inhibit degranulation of cells such as mast or basophil cells that are activated or stimulated with an IgE-specific allergen or binding agent (such as an anti-IgE antibody) but do not appreciably inhibit degranulation of cells that are activated or stimulated with degranulating agents that bypass the FcεRI signaling pathway, such as, for example the calcium ionophores ionomycin and A23187.

[0110] “IgG-Induced Degranulation” or “FcγRI-Mediated Degranulation” refers to degranulation that proceeds via the FcγRI signal transduction cascade initiated by crosslinking of FcγRI-bound IgG. The crosslinking may be induced by an IgG-specific allergen or another multivalent binding agent, such as an anti-IgG or fragment antibody. Like the FcεRI signaling cascade, in mast and basophil cells the FcγRI signaling cascade also leads to degranulation which may be broken into the same two stages: upstream and downstream. Similar to FcεRI-mediated degranulation, compounds that selectively inhibit upstream FcγRI-mediated degranulation act upstream of the point at which calcium ion mobilization is induced. In cell-based assays, compounds that selectively inhibit upstream FcγRI-mediated degranulation inhibit degranulation of cells such as mast or basophil cells that are activated or stimulated with an IgG-specific allergen or binding agent (such as an anti-IgG antibody or fragment) but do not appreciably inhibit degranulation of cells that are activated or stimulated with degranulating agents that bypass the FcγRI signaling pathway, such as, for example the calcium ionophores ionomycin and A23187.

[0111] “Ionophore-Induced Degranulation” or “Ionophore-Mediated Degranulation” refers to degranulation of a cell, such as a mast or basophil cell, that occurs upon exposure to a calcium ionophore such as, for example, ionomycin or A23187.

[0112] “Syk Kinsase” refers to the well-known 72 kDa non-receptor (cytoplasmic) spleen protein tyrosine kinase expressed in B-cells and other hematopoetic cells. Syk kinase includes two consensus Src-homology 2 (SH2) domains in tandem that bind to phosphorylated immunoreceptor tyrosine-based activation motifs (“ITAMs”), a “linker” domain and a catalytic domain (for a review of the structure and function of Syk kinase see Sada et al., 2001, J. Biochem. (Tokyo) 130:177–186); see also Turner et al., 2000, Immunology Today 21:148–154). Syk kinase has been extensively studied as an effector of B-cell receptor (BCR) signaling (Turner et al., 2000, supra). Syk kinase is also critical for tyrosine phosphorylation of multiple proteins which regulate important pathways leading from immunoreceptors, such as Ca²⁺ mobilization and mitogen-activated protein kinase (MAPK) cascades (see, e.g., FIG. 2) and degranulation. Syk kinase also plays a critical role in integrin signaling in neutrophils (see, e.g., Mocsai et al. 2002, Immunity 16:547–558).

[0113] As used herein, Syk kinase includes kinases from any species of animal, including but not limited to, homosapiens, simian, bovine, porcine, rodent, etc., recognized as belonging to the Syk family. Specifically included are isoforms, splice variants, allelic variants, mutants, both naturally occuring and man-made. The amino acid sequences of such Syk kinases are well known and available from GENBANK. Specific examples of mRNAs encoding different isoforms of human Syk kinase can be found at GENBANK accession no. gi|21361552|ref|NM_—003177.2|, gi|496899|emb|Z29630.1|HSSYKPTK[496899] and gi|15030258|gb|BC011399.1|BC011399[15030258], which are incorporated herein by reference.

[0114] Skilled artisans will appreciate that tyrosine kinases belonging to other families may have active sites or binding pockets that are similar in three-dimensional structure to that of Syk. As a consequence of this structural similarity, such kinases, referred to herein as “Syk mimics,” are expected to catalyze phosphorylation of substrates phosphorylated by Syk. Thus, it will be appreciated that such Syk mimics, signal transduction cascades in which such Syk mimics play a role and biological responses effected by such Syk mimics and Syk mimic-dependent signaling cascades may be regulated, and in particular inhibited, with the 2,4-pyrimidinediamine compounds described herein.

[0115] “Syk-Dependent Signaling Cascade” refers to a signal transduction cascade in which Syk kinase plays a role. Non-limiting examples of such Syk-dependent signaling cascades include the FcαRI, FcεRI, FcγRI, FcγRIII, BCR and integrin signaling cascades.

[0126] each R^a is independently selected from the group consisting of hydrogen, (C1–C6) alkyl, (C3–C8) cycloalkyl, cyclohexyl, (C4–C11) cycloalkylalkyl, (C5–C10) aryl, phenyl, (C6–C16) arylalkyl, benzyl, 2–6 membered heteroalkyl, 3–8 membered cycloheteroalkyl, morpholinyl, piperazinyl, homopiperazinyl, piperidinyl, 4–11 membered cycloheteroalkylalkyl, 5–10 membered heteroaryl and 6–16 membered heteroarylalkyl;

[0129] each R^d is independently R^a;

[0130] each m is independently an integer from 1 to 3; and

[0131] each n is independently an integer from 0 to 3.

[0132] In the compounds of structural formula (I), L¹ and L² represent, independently of one another, a direct bond or a linker. Thus, as will be appreciated by skilled artisans, the substituents R² and/or R⁴ may be bonded either directly to their respective nitrogen atoms or, alternatively, spaced away from their respective nitrogen atoms by way of a linker. The identity of the linker is not critical and typical suitable linkers include, but are not limited to, (C1–C6) alkyldiyls, (C1–C6) alkanos and (C1–C6) heteroalkyldiyls, each of which may be optionally substituted with one or more of the same or different R⁸ groups, where R⁸ is as previously defined for structural formula (I). In a specific embodiment, L¹ and L² are each, independently of one another, selected from the group consisting of a direct bond, (C1–C3) alkyldiyl optionally substituted with one or more of the same or different R^a, suitable R^b or R⁹ groups and 1–3 membered heteroalkyldiyl optionally substituted with one or more of the same or different R^a, suitable R^b or R⁹ groups, wherein R⁹ is selected from the group consisting of (C1–C3) alkyl, —OR^a, —C(O)OR^a, (C5–C10) aryl optionally substituted with one or more of the same or different halogens, phenyl optionally substituted with one or more of the same or different halogens, 5–10 membered heteroaryl optionally substituted with one or more of the same or different halogens and 6 membered heteroaryl optionally substituted with one or more of the same or different halogens; and R^a and R^b are as previously defined for structural formula (I). Specific R⁹ groups that may be used to substitute L¹ and L² include —OR^a, —C(O)OR^a, phenyl, halophenyl and 4-halophenyl, wherein R^a is as previously defined for structural formula (I).

[0133] In another specific embodiment, L¹ and L² are each, independently of one another, selected from the group consisting of methano, ethano and propano, each of which may be optionally monosubstituted with an R⁹ group, where R⁹is as previously defined above.

[0134] In all of the above embodiments, specific R^a groups that may be included in R⁹ groups are selected from the group consisting of hydrogen, (C1–C6) alkyl, phenyl and benzyl.

[0135] In still another specific embodiment, L¹ and L² are each a direct bond such that the 2,4-pyrimidinediamine compounds of the invention are compounds according to structural formula (Ia):

[0136]

[0137] including salts, hydrates, solvates and N-oxides thereof, wherein R², R⁴, R⁵ and R⁶ are as previously defined for structural formula (I). Additional specific embodiments of the 2,4-pyrimidinediamine compounds of the invention are described below.

[0138] In a first embodiment of the compounds of structural formulae (I) and (Ia), R², R⁴, R⁵, R⁶, L¹ and L² are as previously defined for their respective structures (I) and (Ia), with the proviso that R² is not 3,4,5-trimethoxyphenyl, 3,4,5-tri (C1–C6) alkoxyphenyl or

[0161] In a fourth embodiment, the compounds of structural formulae (I) and (Ia) exclude compounds according to the following structural formula (Ib):

[0162]

[0163] wherein R²⁴ is (C1–C6) alkyl; and R²¹, R²² and R²³ are as previously defined in connection with the first embodiment.

[0164] In a fifth embodiment, the compounds of structural formulae (I) and (Ia) exclude the compounds described in Examples 1–141 of U.S. Pat. No. 6,235,746, the disclosure of which is incorporated herein by reference.

[0165] In a sixth embodiment, the compounds of structural formulae (I) and (Ia) exclude compounds defined by formula (1) or formula 1(a) of this U.S. Pat. No. 6,235,746 (see, e.g., the disclosure at Col. 1, line 48 through Col. 7, line 49 and Col. 8, lines 9–36, which is incorporated by reference).

[0166] In a seventh embodiment, the compounds of structural formulae (I) and (Ia) exclude compounds in which R⁵ is cyano or —C(O)NHR, where R is hydrogen or (C1–C6) alkyl, when R² is a substituted phenyl; R4 is a substituted or unsubstituted (C1–C6) alkyl, (C₃–C₈) cycloalkyl, 3–8 membered cycloheteralkyl or 5–15 membered heteroaryl; and R⁶ is hydrogen.

[0167] In an eighth embodiment, the compounds of structural formulae (I) and (Ia) exclude the compounds defined by formulae (I) and (X) of WO 02/04429 or any compound disclosed in WO 02/04429, the disclosure of which is incorporated herein by reference.

[0168] In a ninth embodiment of the compounds of structural formulae (I) and (Ia), when R⁵ is cyano or —C(O)NHR, where R is hydrogen or (C1–C6) alkyl; and R⁶ is hydrogen, then R² is other than a substituted phenyl group.

[0169] In a tenth embodiment, the compounds of structural formulae (I) and (Ia) exclude compounds in which R² and R⁴ are each independently a substituted or unsubstituted pyrrole or indole ring which is attached to the remainder of the molecule via its ring nitrogen atom.

[0170] In an eleventh embodiment, the compounds of structural formulae (I) and (Ia) exclude compounds defined by formulae (I) and (IV) of U.S. Pat. No. 4,983,608 or any compound disclosed in U.S. Pat. No. 4,983,608, the disclosure of which is incorporated herein by reference.

[0171] Those of skill in the art will appreciate that in the compounds of formulae (I) and (Ia), R² and R⁴ may be the same or different, and may vary broadly. When R² and/or R⁴ are optionally substituted rings, such as optionally substituted cycloalkyls, cycloheteroalkyls, aryls and heteroaryls, the ring may be attached to the remainder of the molecule through any available carbon or heteroatom. The optional substituents may be attached to any available carbon atoms and/or heteroatoms.

[0172] In a twelfth embodiment of the compounds of structural formulae (I) and (Ia), R² and/or R⁴ is an optionally substituted phenyl or an optionally substituted (C5–C15) aryl, subject to the provisos that (1) when R⁶ is hydrogen, then R² is not 3,4,5-trimethoxyphenyl or 3,4,5-tri (C1–C6) alkoxyphenyl; (2) when R² is a 3,4,5-trisubstituted phenyl, then the substituents at the 3- and 4-positions are not simultaneously methoxy or (C1–C6) alkoxy; or (3) when R⁶ is hydrogen and R⁴ is (C1–C6) alkyl, (C₃-C8) cycloalkyl, 3–8 membered cycloheteroalkyl or 5–15 membered heteroaryl, then R⁵ is other than cyano. Alternatively, R² is subject to the provisos described in connection with the first or second embodiments. The optionally substituted aryl or phenyl group may be attached to the remainder of the molecule through any available carbon atom. Specific examples of optionally substituted phenyls include phenyls that are optionally mono-, di- or tri-substituted with the same or different R⁸ groups, where R⁸ is as previously defined for structural formula (I) and subject to the above provisos. When the phenyl is mono-substituted, the R⁸ substituent may be positioned at either the ortho, meta or para position. When positioned at the ortho, meta or para position, R⁸ is preferably selected from the group consisting of (C1-C10) alkyl, (C1–C10) branched alkyl, —OR^a optionally substituted with one or more of the same or different R^b groups, —O—C(O)OR^a, —O—(CH₂)_m—C(O)OR^a, —C(O)OR^a, —O—(CH₂)_m—NR^cR^c, —O—C(O)NR^cR^c, —O—(CH₂)_m—C(O)NR^cR^c, —O—C(NH)NR^cR^c, —O—(CH₂)_m—C(NH)NR^cR^c and —NH—(CH₂)_m—NR^cR^c, where m, R^a and R^c are as previously defined for structural formula (I). In one embodiment of these compounds, —NR^cR^c is a 5–6 membered heteroaryl which optionally includes one or more of the same or different additional heteroatoms. Specific examples of such 5–6 membered heteroaryls include, but are not limited to, oxadiazolyl, triazolyl, thiazolyl, oxazolyl, tetrazolyl and isoxazolyl.

[0173] In another embodiment of these compounds, —NR^cR^c is a 5–6 membered saturated cycloheteroalkyl ring which optionally includes one or more of the same or different heteroatoms. Specific examples of such cycloheteroalkyls include, but are not limited to, pyrrolidinyl, pyrazolidinyl, imidazolidinyl, piperidinyl, piperazinyl and morpholinyl.

[0174] In still another embodiment of these compounds, each R^a is independently a (C1–C6) alkyl and/or each —NR^cR^c is —NHR^a, where R^a is a (C1–C6) alkyl. In one specific embodiment, R⁸ is —O—CH₂—C(O)NHCH₃. In another specific embodiment R⁸ is —OH.

[0175] When the phenyl is di-substituted or tri-substituted, the R⁸ substituents may be positioned at any combination of positions. For example, the R⁸ substituents may be positioned at the 2,3-, 2,4-, 2,5-, 2,6-, 3,4-, 3,5-, 2,3,4-, 2,3,5-, 2,3,6-, 2,4,5-, 2,4,6-, 2,5,6- or 3,4,5-positions. In one embodiment of compounds including a disubstituted phenyl, the substituents are positioned other than 3,4. In another embodiment they are positioned 3,4. In one embodiment of compounds including a trisubstituted phenyl, the substituents are positioned other than 3,4,5 or, alternatively, no two of the substituents are positioned 3,4.

[0180] wherein: R³¹ is methyl or (C1–C6) alkyl; R³² is hydrogen, methyl or (C1–C6) alkyl; and R³³ is a halo group.

[0181] In a thirteenth embodiment of the compounds of structural formulae (I) and (Ia), R² and/or R⁴ is an optionally substituted heteroaryl. Typical heteroaryl groups according to this thirteenth embodiment comprise from 5 to 15, and more typically from 5 to 11 ring atoms, and include one, two, three or four of the same or different heteratoms or heteroatomic groups selected from the group consisting of N, NH, O, S, S(O) and S(O)₂. The optionally substituted heteroaryl may be attached to its respective C2 or C4 nitrogen atom or linker L¹ or L² through any available carbon atom or heteroatom, but is typically attached via a carbon atom. The optional substituents may be the same or different, and may be attached to any available carbon atom or heteroatom. In one embodiment of these compounds, R⁵ is other than bromo, nitro, trifluoromethyl, cyano or —C(O)NHR, where R is hydrogen or (C1–C6) alkyl. In another embodiment of these compounds, when R² and R⁴ are each a substituted or unsubstituted pyrrole or indole, then the ring is attached to the remainder of the molecule via a ring carbon atom. In still another embodiment of compounds including an optionally substituted heteroaryl group, the heteroaryl is unsubstituted or substituted with from one to four of the same or different R⁸ groups, where R⁸ is as previously defined for structural formula (I). Specific examples of such optionally substituted heteroaryls include, but are not limited to, the following heteroaryl groups:

[0201] In one embodiment of the above-depicted heteroaryls, as well as other 5–15 membered heteroaryls according to this embodiment of the invention, each R⁸ is independently selected from the group consisting of R^d, —NR^cR^c, —(CH₂)_m—NR^cR^c, —C(O)NR^cR^c, —(CH₂)_m—C(O)NR^cR^c, —C(O)OR^d, —(CH₂)_m—C(O)OR^d and —(CH₂)_m—OR^d, where m, R^c and R^d are as previously defined for structural formula (I).

[0206] In this fourteenth embodiment of the invention, the R² and R⁴ substituents may be the same or different. Specific optionally substituted phenyl, aryl and/or heteroaryls include those illustrated above in connection with the twelfth and thirteenth embodiments.

[0207] In a fifteenth embodiment of the compounds of structural formulae (I) and (Ia), including the above-described first through fourteenth embodiments thereof, R⁶ is hydrogen and R⁵ is an electronegative group. As will be recognized by skilled artisans, electronegative groups are atoms or groups of atoms that have a relatively great tendency to attract electrons to themselves. Specific examples of electronegative groups according to this fourteenth embodiment include, but are not limited to, —CN, —NC, —NO₂, halo, bromo, chloro, fluoro, (C1–C3) haloalkyl, (C1–C3) perhaloalkyl, (C1–C3) fluoroalkyl, (C1–C3) perfluoroalkyl, —CF₃, (C1–C3) haloalkoxy, (C1–C3) perhaloalkoxy, (C1–C3) fluoroalkoxy, (C1–C3) perfluoroalkoxy, —OCF₃, —C(O)R^a, —C(O)OR^a, —C(O)CF₃ and —C(O)OCF₃.

[0210] and salts, hydrates, solvates and N-oxides thereof, wherein R¹¹, R¹², R¹³ and R¹⁴ are each, independently of one another, selected from the group consisting of hydrogen, hydroxy, (C1–C6) alkoxy and —NR^cR^c; and R⁵, R⁶ and R^c are as previously defined for structural formula (I), with the proviso that when R¹³, R⁵ and R⁶ are each hydrogen, then R¹¹ and R¹² are not simultaneously methoxy, (C1–C6) alkoxy or (C1–C6) haloalkoxy

[0211] In a seventeenth embodiment, the compounds of structural formulae (I) and (Ia) are compounds according to structural formula (Ic):

[0212]

[0213] and salts, hydrates, solvates and N-oxides thereof, wherein:

[0214] R⁴ is selected from the group consisting of 5–10 membered heteroaryl and 3-hydroxyphenyl;

[0215] R⁵ is F or —CF₃; and

[0216] R⁸ is —O(CH₂)_m—R^b, where m and R^b are as previously defined for structural formula (I). In a specific embodiment, R⁸ is —O—CH₂—C(O)NH-CH₃ and/or R⁴ is a heteroaryl according to the thirteenth embodiment.

[0217] In an eighteenth embodiment, the compounds of structural formulae (I) and (Ia) include any compound selected from TABLE 1 that inhibits an Fc receptor signal transduction cascade, a Syk kinase activity, a Syk-kinase dependent receptor signal transduction cascade or cell degranulation as measured in an in vitro assay, optionally subject to the proviso that the compound is not a compound excluded by the above-described third embodiment and/or other embodiments. In a specific embodiment, such compounds have an IC₅₀ of about 20 μM or less as measured in an in vitro degranulation assay, such as one of the degranulation assays described in the Examples section.

[0218] In a nineteenth embodiment, the compounds of structural formulae (I) and (Ia) include any compound selected from TABLE 1 that inhibits the FcγR1 or FcεR1 receptor cascade with an IC₅₀ of about 20 μM or less as measured in an in vitro assay, such as one of the in vitro assays provided in the Examples section, optionally subject to the proviso that the compound is not a compound excluded by the above-described third embodiment and/or other embodiments.

[0219] Also specifically described are combinations of the above first through nineteenth specific embodiments.

[0220] Those of skill in the art will appreciate that the 2,4-pyrimidinediamine compounds described herein may include functional groups that can be masked with progroups to create prodrugs. Such prodrugs are usually, but need not be, pharmacologically inactive until converted into their active drug form. Indeed, many of the active 2,4-pyrimidinediamine compounds described in TABLE 1, infra, include promoieties that are hydrolyzable or otherwise cleavable under conditions of use. For example, ester groups commonly undergo acid-catalyzed hydrolysis to yield the parent carboxylic acid when exposed to the acidic conditions of the stomach, or base-catalyzed hydrolysis when exposed to the basic conditions of the intestine or blood. Thus, when administered to a subject orally, 2,4-pyrimidinediamines that include ester moieties may be considered prodrugs of their corresponding carboxylic acid, regardless of whether the ester form is pharmacologically active. Referring to TABLE 1, numerous ester-containing 2,4-pyrimidinediamines of the invention are active in their ester, “prodrug” form.

[0221] In the prodrugs of the invention, any available functional moiety may be masked with a progroup to yield a prodrug. Functional groups within the 2,4-pyrimidinediamine compounds that may be masked with progroups for inclusion in a promoiety include, but are not limited to, amines (primary and secondary), hydroxyls, sulfanyls (thiols), carboxyls, etc. Myriad progroups suitable for masking such functional groups to yield promoieties that are cleavable under the desired conditions of use are known in the art. All of these progroups, alone or in combinations, may be included in the prodrugs of the invention.

[0222] In one illustrative embodiment, the prodrugs of the invention are compounds according to structural formula (1) in which R^c and R^d may be, in addition to their previously-defined alternatives, a progroup.

[0223] Replacing the hydrogens attached to N2 and N4 in the 2,4-pyrimidinediamines of structural formula (I) with substituents adversely effects the activity of the compounds. However, as will be appreciated by skilled artisans, these nitrogens may be included in promoieties that, under conditions of use, cleave to yield 2,4-pyrimidinediamines according to structural formula (I). Thus, in another embodiment, the prodrugs of the invention are compounds according to structural formula (II):

[0224]

[0225] including salts, hydrates, solvates and N-oxides thereof, wherein:

[0226] R², R⁴, R⁵, R⁶, L¹ and L² are as previously defined for structural formula (I); and

[0227] R^2b and R^4b are each, independently of one another, a progroup. Specific examples of progroups according to this embodiment of the invention include, but are not limited to, (C1–C6) alkyl, —C(O)CH₃, —C(O)NHR³⁶ and —S(O)₂R³⁶, where R³⁶ is (C1–C6) alkyl, (C5–C15) aryl and (C3–C8) cycloalkyl.

[0228] In the prodrugs of structural formula (II), the various substituents may be as described for the various first through twentieth embodiments previously described for the compounds of structural formulae (I) and (Ia), or combinations of such embodiments.

[0229] Those of skill in the art will appreciate that many of the compounds and prodrugs of the invention, as well as the various compound species specifically described and/or illustrated herein, may exhibit the phenomena of tautomerism, conformational isomerism, geometric isomerism and/or optical isomerism. For example, the compounds and prodrugs of the invention may include one or more chiral centers and/or double bonds and as a consequence may exist as stereoisomers, such as double-bond isomers (i.e., geometric isomers), enantiomers and diasteromers and mixtures thereof, such as racemic mixtures. As another example, the compounds and prodrugs of the invention may exist in several tautomeric forms, including the enol form, the keto form and mixtures thereof. As the various compound names, formulae and compound drawings within the specification and claims can represent only one of the possible tautomeric, conformational isomeric, optical isomeric or geometric isomeric forms, it should be understood that the invention encompasses any tautomeric, conformational isomeric, optical isomeric and/or geometric isomeric forms of the compounds or prodrugs having one or more of the utilities described herein, as well as mixtures of these various different isomeric forms. In cases of limited rotation around the 2,4-pryimidinediamine core structure, atrop isomers are also possible and are also specifically included in the compounds of the invention.

[0230] Moreover, skilled artisans will appreciate that when lists of alternative substituents include members which, owing to valency requirements or other reasons, cannot be used to substitute a particular group, the list is intended to be read in context to include those members of the list that are suitable for substituting the particular group. For example, skilled artisans will appreciate that while all of the listed alternatives for R^b can be used to substitute an alkyl group, certain of the alternatives, such as ═O, cannot be used to substitute a phenyl group. It is to be understood that only possible combinations of substituent-group pairs are intended.

[0231] The compounds and/or prodrugs of the invention may be identified by either their chemical structure or their chemical name. When the chemical structure and the chemical name conflict, the chemical structure is determinative of the identity of the specific compound.

[0232] Depending upon the nature of the various substituents, the 2,4-pyrimidinediamine compounds and prodrugs of the invention may be in the form of salts. Such salts include salts suitable for pharmaceutical uses (“pharmaceutically-acceptable salts”), salts suitable for veterinary uses, etc. Such salts may be derived from acids or bases, as is well-known in the art.

[0233] In one embodiment, the salt is a pharmaceutically acceptable salt. Generally, pharmaceutically acceptable salts are those salts that retain substantially one or more of the desired pharmacological activities of the parent compound and which are suitable for administration to humans. Pharmaceutically acceptable salts include acid addition salts formed with inorganic acids or organic acids. Inorganic acids suitable for forming pharmaceutically acceptable acid addition salts include, by way of example and not limitation, hydrohalide acids (e.g., hydrochloric acid, hydrobromic acid, hydriodic, etc.), sulfuric acid, nitric acid, phosphoric acid, and the like. Organic acids suitable for forming pharmaceutically acceptable acid addition salts include, by way of example and not limitation, acetic acid, trifluoroacetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, oxalic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, tartaric acid, citric acid, palmitic acid, benzoic acid, 3-(4-hydroxybenzoyl) benzoic acid, cinnamic acid, mandelic acid, alkylsulfonic acids (e.g., methanesulfonic acid, ethanesulfonic acid, 1,2-ethane-disulfonic acid, 2-hydroxyethanesulfonic acid, etc.), arylsulfonic acids (e.g., benzenesulfonic acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, etc.), 4-methylbicyclo[2.2.2]-oct-2-ene-1-carboxylic acid, glucoheptonic acid, 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic acid, and the like.

[0234] Pharmaceutically acceptable salts also include salts formed when an acidic proton present in the parent compound is either replaced by a metal ion (e.g., an alkali metal ion, an alkaline earth metal ion or an aluminum ion) or coordinates with an organic base (e.g., ethanolamine, diethanolamine, triethanolamine, N-methylglucamine, morpholine, piperidine, dimethylamine, diethylamine, etc.).

[0235] The 2,4-pyrimidinediamine compounds and of the invention, as well as the salts thereof, may also be in the form of hydrates, solvates and N-oxides, as are well-known in the art.

[0236] 6.3 Methods of Synthesis

[0237] The compounds and prodrugs of the invention may be synthesized via a variety of different synthetic routes using commercially available starting materials and/or starting materials prepared by conventional synthetic methods. Suitable exemplary methods that may be routinely adapted to synthesize the 2,4-pyrimidinediamine compounds and prodrugs of the invention are found in U.S. Pat. No. 5,958,935, the disclosure of which is incorporated herein by reference. Specific examples describing the synthesis of numerous compounds and prodrugs of the invention, as well as intermediates therefor, are provided in the Examples section. All of the compounds of structural formulae (I), (Ia) and (II) may be prepared by routine adaptation of these methods.

[0238] A variety of exemplary synthetic routes that can be used to synthesize the 2,4-pyrimidinediamine compounds of the invention are described in Schemes (I)–(XI), below. In Schemes (I)–(XI), like-numbered compounds have similar structures. These methods may be routinely adapted to synthesize the prodrugs according to structural formula (II).

[0239] In one exemplary embodiment, the compounds can be synthesized from substituted or unsubstituted uracils or thiouracils as illustrated in Scheme (I), below:

[0240]

[0241] In Scheme (I), R², R⁴, R⁵, R⁶, L¹ and L² are as previously defined for structural formula (I), X is a halogen (e.g., F, Cl, Br or I) and Y and Y′ are each, independently of one another, selected from the group consisting of O and S. Referring to Scheme (I), uracil or thiouracil 2 is dihalogenated at the 2- and 4-positions using standard halogenating agent POX₃ (or other standard halogenating agent) under standard conditions to yield 2,4-bishalo pyrimidine 4. Depending upon the R⁵ substituent, in pyrimidine 4, the halide at the C4 position is more reactive towards nucleophiles than the halide at the C2 position. This differential reactivity can be exploited to synthesize 2,4-pyrimidinediamines according structural formula (I) by first reacting 2,4-bishalopyrimidine 4 with one equivalent of amine 10, yielding 4N-substituted-2-halo4-pyrimidineamine 8, followed by amine 6 to yield a 2,4-pyrimidinediamine according structural formula (I). 2N,4N-bis(substituted)-2,4-pyrimidinediamines 12 and 14 can be obtained by reacting 2,4-bishalopyrimidine 4 with excess 6 or 10, respectively.

[0242] In most situations, the C4 halide is more reactive towards nucleophiles, as illustrated in the Scheme. However, as will be recognized by skilled artisans, the identity of the R⁵ substituent may alter this reactivity. For example, when R⁵ is trifluoromethyl, a 50:50 mixture of 4N-substituted-4-pyrimidineamine 8 and the corresponding 2N-substituted-2-pyrimidineamine is obtained. Regardless of the identity of the R⁵ substituent, the regioselectivity of the reaction can be controlled by adjusting the solvent and other synthetic conditions (such as temperature), as is well-known in the art.

[0243] The reactions depicted in Scheme (I) may proceed more quickly when the reaction mixtures are heated via microwave. When heating in this fashion, the following conditions may be used: heat to 175° C. in ethanol for 5–20 min. in a Smith Reactor (Personal Chemistry) in a sealed tube (at 20 bar pressure).

[0244] The uracil or thiouracil 2 starting materials may be purchased from commercial sources or prepared using standard techniques of organic chemistry.

Sources Int'l 2000; CAS Registry 5435-16-5); 5-(trifluoromethyl)-uracil (Aldrich #22,327-1; CAS Registry 54-20-6); 5-(2,2,2-trifluoroethyl)-uracil (CAS Registry 155143-31-6); 5-(pentafluoroethyl)-uracil (CAS Registry 60007-38-3); 6-aminouracil (Aldrich #A5060-6; CAS Registry 873-83-6) uracil-6-carboxylic acid (orotic acid; Aldrich #0-840-2; CAS Registry 50887-69-9); 6-methyluracil (Aldrich #D11,520-7; CAS Registry 62648-2); uracil-5-amino-6-carboxylic acid (5-aminoorotic acid; Aldrich #19,121-3; CAS Registry #7164-43-4); 6-amino-5-nitrosouracil (6-amino-2,4-dihydroxy-5-nitrosopyrimidine; Aldrich #27,689-8; CAS Registry 5442-24-0); uracil-5-fluoro-6-carboxylic acid (5-fluoroorotic acid; Aldrich #42,513-3; CAS Registry 00000-00-0); and uracil-5-nitro-6-carboxylic acid (5-nitroorotic acid; Aldrich #18,528-0; CAS Registry 600779-49-9). Additional 5-, 6- and 5,6-substituted uracils and/or thiouracils are available from General Intermediates of Canada, Inc., Edmonton, Calif. (www.generalintermediates.com) and/or Interchim, Cedex, France (www.interchim.com), or may be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

[0245] Amines 6 and 10 may be purchased from commercial sources or, alternatively, may be synthesized utilizing standard techniques. For example, suitable amines may be synthesized from nitro precursors using standard chemistry. Specific exemplary reactions are provided in the Examples section. See also Vogel, 1989, Practical Organic Chemistry, Addison Wesley Longman, Ltd. and John Wiley & Sons, Inc.

[0246] Skilled artisans will recognize that in some instances, amines 6 and 10 and/or substituents R⁵ and/or R⁶ on uracil or thiouracil 2 may include functional groups that require protection during synthesis. The exact identity of any protecting group(s) used will depend upon the identity of the functional group being protected, and will be apparent to these of skill in the art. Guidance for selecting appropriate protecting groups, as well as synthetic strategies for their attachment and removal, may be found, for example, in Greene & Wuts, Protective Groups in Organic Synthesis, 3d Edition, John Wiley & Sons, Inc., New York (1999) and the references cited therein (hereinafter “Greene & Wuts”).

[0247] A specific embodiment of Scheme (I) utilizing 5-fluorouracil (Aldrich #32,937-1) as a starting material is illustrated in Scheme (Ia), below:

[0248]

[0249] In Scheme (Ia), R², R⁴, L¹ and L² are as previously defined for Scheme (I). According to Scheme (Ia), 5-fluorouracil 3 is halogenated with POCl₃ to yield 2,4-dichloro-5-fluoropyrimidine 5, which is then reacted with excess amine 6 or 10 to yield N2,N4-bis substituted 5-fluoro-2,4-pyrimidinediamine 11 or 13, respectively. Alternatively, asymmetric 2N,4N-disubstituted-5-fluoro-2,4-pyrimidinediamine 9 may be obtained by reacting 2,4-dichloro-5-fluoropyrimidine 5 with one equivalent of amine 10 (to yield 2-chloro-N4-substituted-5-fluoro-4-pyrimidineamine 7) followed by one or more equivalents of amine 6.

[0250] In another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention may be synthesized from substituted or unsubstituted cytosines as illustrated in Schemes (IIa) and (IIb), below:

[0251]

[0252]

[0253] In Schemes (IIa) and (IIb), R², R⁴, R⁵, R⁶, L¹, L² and X are as previously defined for Scheme (I) and PG represents a protecting group. Referring to Scheme (IIa), the C4 exocyclic amine of cytosine 20 is first protected with a suitable protecting group PG to yield N4-protected cytosine 22. For specific guidance regarding protecting groups useful in this context, see Vorbrüggen and Ruh-Pohlenz, 2001, Handbook of Nucleoside Synthesis, John Wiley & Sons, NY, pp. 1–631 (“Vorbrüggen”). Protected cytosine 22 is halogenated at the C2 position using a standard halogenation reagent under standard conditions to yield 2-chloro4N-protected4-pyrimidineamine 24. Reaction with amine 6 followed by deprotection of the C4 exocyclic amine and reaction with amine 10 yields a 2,4-pyrimidinediamine according to structural formula (I).

[0254] Alternatively, referring to Scheme (IIb), cytosine 20 may be reacted with amine 10 or protected amine 21 to yield N4-substituted cytosine 23 or 27, respectively. These substituted cytosines may then be halogenated as previously described, deprotected (in the case of N4-substituted cytosine 27) and reacted with amine 6 to yield a 2,4-pyrimidinediamine according to structural formula (I).

[0255] Commercially-available cytosines that may be used as starting materials in Schemes (IIa) and (IIb) include, but are not limited to, cytosine (Aldrich #14,201-8; CAS Registry 71-30-7); N⁴-acetylcytosine (Aldrich #37,791-0; CAS Registry 14631-20-0); 5-fluorocytosine (Aldrich #27,159-4; CAS Registry 2022-85-7); and 5-(trifluoromethyl)-cytosine. Other suitable cytosines useful as starting materials in Schemes (IIa) are available from General Intermediates of Canada, Inc., Edmonton, Calif. (www.generalintermediates.com) and/or Interchim, Cedex, France (www.interchim.com), or may be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

[0256] In still another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention may be synthesized from substituted or unsubstituted 2-amino4-pyrimidinols as illustrated in Scheme (III), below:

[0257]

[0258] In Scheme (III), R², R⁴, R⁵, R⁶, L¹, L² and X are as previously defined for Scheme (I) and Z is a leaving group as discussed in more detail in connection with Scheme IV, infra. Referring to Scheme (III), 2-amino-4-pyrimidinol 30 is reacted with amine 6 (or optionally protected amine 21) to yield N2-substituted4-pyrimidinol 32, which is then halogenated as previously described to yield N2-substituted4-halo-2-pyrimidineamine 34. Optional deprotection (for example if protected amine 21 was used in the first step) followed by reaction with amine 10 affords a 2,4-pyrimidinediamine according to structural formula (I). Alternatively, pyrimidinol 30 can be reacted with acylating agent 31.

[0259] Suitable commercially-available 2-amino4-pyrimidinols 30 that can be used as starting materials in Scheme (III) include, but are not limited to, 2-amino-6-chloro-4-pyrimidinol hydrate (Aldrich #A4702-8; CAS Registry 00000-00-0) and 2-amino-6-hydroxy4-pyrimidinol (Aldrich #A5040-1; CAS Registry 56-09-7). Other 2-amino-4-pyrimidinols 30 useful as starting materials in Scheme (III) are available from General Intermediates of Canada, Inc., Edmonton, Calif.

Myriad textbook references teaching suitable synthetic methods are provided infra.

[0260] Alternatively, the 2,4-pyrimidinediamine compounds of the invention may be prepared from substituted or unsubstituted 4-amino-2-pyrimidinols as illustrated in Scheme (IV), below:

[0261]

[0262] In Scheme (IV), R², R⁴, R⁵, R⁶, L¹ and L² are as previously defined for Scheme (I) and Z represents a leaving group. Referring to Scheme (IV), the C2-hydroxyl of 4-amino-2-pyrimidinol 40 is more reactive towards nucleophiles than the C4-amino such that reaction with amine 6 yields N2-substituted-2,4-pyrimidinediamine 42. Subsequent reaction with compound 44, which includes a good leaving group Z, or amine 10 yields a 2,4-pyrimidinediamine according to structural formula (I). Compound 44 may include virtually any leaving group that can be displaced by the C4-amino of N2-substituted-2,4-pyrimidinediamine 42. Suitable leaving groups Z include, but are not limited to, halogens, methanesulfonyloxy (mesyloxy; “OMs”), trifluoromethanesulfonyloxy (“OTf”) and p-toluenesulfonyloxy (tosyloxy; “OTs”), benzene sulfonyloxy (“besylate”) and metanitro benzene sulfonyloxy (“nosylate”). Other suitable leaving groups will be apparent to those of skill in the art.

[0263] Substituted 4-amino-2-pyrimidinol starting materials may be obtained commercially or synthesized using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

[0264] In still another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention can be prepared from 2-chloro-4-aminopyrimidines or 2-amino-4-chloropyrimidines as illustrated in Scheme (V), below:

[0265]

[0266] In Scheme (V), R², R⁴, R⁵, R⁶, L¹, L² and X are as defined for Scheme (I) and Z is as defined for Scheme (IV). Referring to Scheme (V), 2-amino4-chloropyrimidine 50 is reacted with amino 10 to yield 4N-substituted-2-pyrimidineamine 52 which, following reaction with compound 31 or amine 6, yields a 2,4-pyrimidinediamine according to structural formula (I). Alternatively, 2-chloro-4-amino-pyrimidine 54 may be reacted with compound 44 followed by amine 6 to yield a compound according to structural formula (I).

[0267] A variety of pyrimidines 50 and 54 suitable for use as starting materials in Scheme (V) are commercially available, including by way of example and not limitation, 2-amino-4,6-dichloropyrimidine (Aldrich #A4860-1; CAS Registry 56-05-3); 2-amino-4-chloro-6-methoxy-pyrimidine (Aldrich #51,864-6; CAS Registry 5734-64-5); 2-amino-4-chloro-6-methylpyrimidine (Aldrich #12,288-2; CAS Registry 5600-21-5); and 2-amino4-chloro-6-methylthiopyrimidine (Aldrich #A4600-5; CAS Registry 1005-38-5). Additional pyrimidine starting materials are available from General Intermediates of Canada, Inc., Edmonton, Calif. (www.generalintermediates.com) and/or Interchim, Cedex, France (www.interchim.com), or may be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

[0268] Alternatively, 4-chloro-2-pyrimidineamines 50 may be prepared as illustrated in Scheme (Va):

[0269]

[0270] In Scheme (Va), R⁵ and R⁶ are as previously defined for structural formula (I). In Scheme (Va), dicarbonyl 53 is reacted with guanidine to yield 2-pyrimidineamine 51. Reaction with peracids like m-chloroperbenzoic acid, trifluoroperacetic acid or urea hydrogen peroxide complex yields N-oxide 55, which is then halogenated to give 4-chloro-2-pyrimidineamine 50. The corresponding 4-halo-2-pyrimidineamines may be obtained by using suitable halogenation reagents.

[0271] In yet another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention can be prepared from substituted or unsubstituted uridines as illustrated in Scheme (VI), below:

[0272]

[0273] In Scheme (VI), R², R⁴, R⁵, R⁶, L¹, L² and X are as previously defined for Scheme (I) and the superscript PG represents a protecting group, as discussed in connection with Scheme (IIb). According to Scheme (VI), uridine 60 has a C4 reactive center such that reaction with amine 10 or protected amine 21 yields N4-substituted cytidine 62 or 64, respectively. Acid-catalyzed deprotection of N4-substituted 62 or 64 (when “PG” represents an acid-labile protecting group) yields N4-substituted cytosine 28, which may be subsequently halogenated at the C2-position and reacted with amine 6 to yield a 2,4-pyrimidinediamine according to structural formula (I).

[0274] Cytidines may also be used as starting materials in an analogous manner, as illustrated in Scheme (VII), below:

[0275]

[0276] In Scheme (VII), R², R⁴, R⁵, R⁶, L¹, L² and X are as previously defined in Scheme (I) and the superscript PG represents a protecting group as discussed above. Referring to Scheme (VII), like uridine 60, cytidine 70 has a C4 reactive center such that reaction with amine 10 or protected amine 21 yields N4-substituted cytidine 62 or 64, respectively. These cytidines 62 and 64 are then treated as previously described for Scheme (VI) to yield a 2,4-pyrimidinediamine according to structural formula (I).

[0277] Although Schemes (VI) and (VII) are exemplified with ribosylnucleosides, skilled artisans will appreciate that the corresponding 2′-deoxyribo and 2′,3′-dideoxyribo nucleosides, as well as nucleosides including sugars or sugar analogs other than ribose, would also work.

[0278] Numerous uridines and cytidines useful as starting materials in Schemes (VI) and (VII) are known in the art, and include, by way of example and not limitation, 5-trifluoromethyl-2′-deoxycytidine (Chem. Sources #ABCR F07669; CAS Registry 66,384-66-5); 5-bromouridine (Chem. Sources Int'l 2000; CAS Registry 957-75-5); 5-iodo-2′-deoxyuridine (Aldrich #1-775-6; CAS Registry 5442-2); 5-fluorouridine (Aldrich #32,937-1; CAS Registry 316-46-1); 5-iodouridine (Aldrich #85,259-7; CAS Registry 1024-99-3); 5-(trifluoromethyl)uridine (Chem. Sources Int'l 2000; CAS Registry 70-00-8); 5-trifluoromethyl-2′-deoxyuridine (Chem. Sources Int'l 2000; CAS Registry 70-00-8). Additional uridines and cytidines that can be used as starting materials in Schemes (VI) and (VII) are available from General Intermediates of Canada, Inc., Edmonton, Calif. (www.generalintermediates.com) and/or Interchim, Cedex, France (www.interchim.com), or may be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.

[0279] The 2,4-pyrimidinediamine compounds of the invention can also be synthesized from substituted pyrimidines, such as chloro-substituted pyrimidines, as illustrated in Schemes (VII) and (IX), below:

[0280]

[0281]

[0282] In Schemes (VIII) and (IX), R², R⁴, L¹, L² and R^a are as previously defined for structural formula (I) and “Ar” represents an aryl group. Referring to Scheme (VIII), reaction of 2,4,6-trichloropyrimidine 80 (Aldrich #T5,620-0; CAS#3764-01-0) with amine 6 yields a mixture of three compounds: substituted pyrimidine mono-, di- and triamines 81, 82 and 83, which can be separated and isolated using HPLC or other conventional techniques. Mono- and diamines 81 and 82 may be further reacted with amines 6 and/or 10 to yield N2,N4,N6-trisubstituted-2,4,6-pyrimidinetriamines 84 and 85, respectively.

[0283] N2,N4-bis-substituted-2,4-pyrimidinediamines can be prepared in a manner analogous to Scheme (VIII) by employing 2,4-dichloro-5-methylpyrimidine or 2,4-dichloro-pyrimidine as starting materials. In this instance, the mono-substituted pyrimidineamine corresponding to compound 81 is not obtained. Instead, the reaction proceeds to yield the N2,N4-bis-substituted-2,4-pyrimidinediamine directly.

[0284] Referring to Scheme (IX), 2,4,5,6-tetrachloropyrimidine 90 (Aldrich #24,671-9; CAS#1780-40-1) is reacted with excess amine 6 to yield a mixture of three compounds: 91, 92, and 93, which can be separated and isolated using HPLC or other conventional techniques. As illustrated, N2,N4-bis-substituted-5,6,-dichloro-2,4-pyrimidinediamine 92 may be further reacted at the C6 halide with, for example a nucleophilic agent 94 to yield compound 95. Alternatively, compound 92 can be converted into N2,N4-bis-substituted-5-chloro-6-aryl-2,4-pyrimidinediamine 97 via a Suzuki reaction. 2,4-Pyrimidinediamine 95 may be converted to 2,4-pyrimidinediamine 99 by reaction with Bn₃SnH.

[0285] As will be recognized by skilled artisans, 2,4-pyrimidinediamines according to the invention, synthesized via the exemplary methods described above or by other well-known means, may also be utilized as starting materials and/or intermediates to synthesize additional 2,4-pyrimidinediamine compounds of the invention. A specific example is illustrated in Scheme (X), below:

[0286]

[0287] In Scheme (X), R⁴, R⁵, R⁶, L² and R^a are as previously defined for structural formula (I). Each R^a′ is independently an R^a, and may be the same or different from the illustrated R^a. Referring to Scheme (X), carboxylic acid or ester 100 may be converted to amide 104 by reaction with amine 102. In amine 102, R^a′ may be the same or different than R^a of acid or ester 100. Similarly, carbonate ester 106 may be converted to carbamate 108.

[0288] A second specific example is illustrated in Scheme (XI), below:

[0289]

[0290] In Scheme (XI), R⁴, R⁵, R⁶, L² and R^c are as previously defined for structural formula (I). Referring to Scheme (XI), amide 110 or 116 may be converted to amine 114 or 118, respectively, by borane reduction with borane methylsulfide complex 112. Other suitable reactions for synthesizing 2,4-pyrimidinediamine compounds from 2,4-pyrimidinediamine starting materials will be apparent to those of skill in the art.

[0291] Although many of the synthetic schemes discussed above do not illustrate the use of protecting groups, skilled artisans will recognize that in some instances substituents R², R⁴, R⁵, R⁶, L¹ and/or L² may include functional groups requiring protection. The exact identity of the protecting group used will depend upon, among other things, the identity of the functional group being protected and the reaction conditions used in the particular synthetic scheme, and will be apparent to those of skill in the art. Guidance for selecting protecting groups and chemistries for their attachment and removal suitable for a particular application can be found, for example, in Greene & Wuts, supra.

[0292] Prodrugs according to structural formula (II) may be prepared by routine modification of the above-described methods. Alternatively, such prodrugs may be prepared by reacting a suitably protected 2,4-pyrimidinediamine of structural formula (I) with a suitable progroup. Conditions for carrying out such reactions and for deprotecting the product to yield a prodrug of formula (II) are well-known.

[0294] 6.4 Inhibition of Fc Receptor Signal Cascades

[0295] Active 2,4-pyrimidinediamine compounds of the invention inhibit Fc receptor signalling cascades that lead to, among other things, degranulation of cells. As a specific example, the compounds inhibit the FcεRI and/or FcγRI signal cascades that lead to degranulation of immune cells such as neutrophil, eosinophil, mast and/or basophil cells. Both mast and basophil cells play a central role in allergen-induced disorders, including, for example, allergic rhinitis and asthma. Referring to FIG. 1, upon exposure allergens, which may be, among other things, pollen or parasites, allergen-specific IgE antibodies are synthesized by B-cells activated by IL-4 (or IL-13) and other messengers to switch to IgE class specific antibody synthesis. These allergen-specific IgEs bind to the high affinity FcεRI. Upon binding of antigen, the FcεR1-bound IgEs are cross-linked and the IgE receptor signal transduction pathway is activated, which leads to degranulation of the cells and consequent release and/or synthesis of a host of chemical mediators, including histamine, proteases (e.g., tryptase and chymase), lipid mediators such as leukotrienes (e.g., LTC4), platelet-activating factor (PAF) and prostaglandins (e.g., PGD2) and a series of cytokines, including TNF-α, IL-4, IL-13, IL-5, IL-6, IL-8, GMCSF, VEGF and TGF-β. The release and/or synthesis of these mediators from mast and/or basophil cells accounts for the early and late stage responses induced by allergens, and is directly linked to downstream events that lead to a sustained inflammatory state.

[0296] The molecular events in the FcεRI signal transduction pathway that lead to release of preformed mediators via degranulation and release and/or synthesis of other chemical mediators are well-known and are illustrated in FIG. 2. Referring to FIG. 2, the FcεRI is a heterotetrameric receptor composed of an IgE-binding alpha-subunit, a beta subunit, and two gamma subunits (gamma homodimer). Cross-linking of FcεRI-bound IgE by multivalent binding agents (including, for example IgE-specific allergens or anti-IgE antibodies or fragments) induces the rapid association and activation of the Src-related kinase Lyn. Lyn phosphorylates immunoreceptor tyrosine-based activation motifs (ITAMS) on the intracellular beta and gamma subunits, which leads to the recruitment of additional Lyn to the beta subunit and Syk kinase to the gamma homodimer. These receptor-associated kinases, which are activated by intra- and intermolecular phosphorylation, phosphorylate other components of the pathway, such as the Btk kinase, LAT, and phospholipase C-gamma PLC-gamma). Activated PLC-gamma initiates pathways that lead to protein kinase C activation and Ca²⁺ mobilization, both of which are required for degranulation. FcεR1 cross-linking also activates the three major classes of mitogen activated protein (MAP) kinases, i.e. ERK1/2, JNK1/2, and p38. Activation of these pathways is important in the transcriptional regulation of proinflammatory mediators, such as TNF-α and IL-6, as well as the lipid mediator leukotriene CA (LTC4).

[0297] Although not illustrated, the FcγRI signaling cascade is believed to share some common elements with the FcεRI signaling cascade. Importantly, like FcεRI, the FcγRI includes a gamma homodimer that is phosphorylated and recruits Syk, and like FcεRI, activation of the FcγRI signaling cascade leads to, among other things, degranulation. Other Fc receptors that share the gamma homodimer, and which can be regulated by the active 2,4-pyrimidinediamine compounds include, but are not limited to, FcαRI and FcγRIII.

[0298] The ability of the 2,4-pyrimidinediamine compounds of the invention to inhibit Fc receptor signaling cascades may be simply determined or confirmed in in vitro assays. Suitable assays for confirming inhition of FcεRI-mediated degranulation are provided in the Examples section. In one typical assay, cells capable of undergoing FcεRI-mediated degranulation, such as mast or basophil cells, are first grown in the presence of IL-4, Stem Cell Factor (SCF), IL-6 and IgE to increase expression of the FcεRI, exposed to a 2,4-pyrimidinediamine test compound of the invention and stimulated with anti-IgE antibodies (or, alternatively, an IgE-specific allergen). Following incubation, the amount of a chemical mediator or other chemical agent released and/or synthesized as a consequence of activating the FcεRI signaling cascade may be quantified using standard techniques and compared to the amount of the mediator or agent released from control cells (i.e., cells that are stimulated but that are not exposed to test compound). The concentration of test compound that yields a 50% reduction in the quantity of the mediator or agent measured as compared to control cells is the IC₅₀ of the test compound. The origin of the mast or basophil cells used in the assay will depend, in part, on the desired use for the compounds and will be apparent to those of skill in the art. For example, if the compounds will be used to treat or prevent a particular disease in humans, a convenient source of mast or basophil cells is a human or other animal which constitutes an accepted or known clinical model for the particular disease. Thus, depending upon the particular application, the mast or basophil cells may be derived from a wide variety of animal sources, ranging from, for example, lower mammals such as mice and rats, to dogs, sheep and other mammals commonly employed in clinical testing, to higher mammals such as monkeys, chimpanzees and apes, to humans. Specific examples of cells suitable for carrying out the in vitro assays include, but are not limited to, rodent or human basophil cells, rat basophil leukemia cell lines, primary mouse mast cells (such as bone marrow-derived mouse mast cells “BMMC”) and primary human mast cells isolated from cord blood (“CHMC”) or other tissues such as lung. Methods for isolating and culturing these cell types are well-known or are provided in the Examples section (see, e.g., Demo et al., 1999, Cytometry 36(4):340–348 and copending application Ser. No. 10/053,355, filed Nov. 8, 2001, the disclosures of which are incorporated herein by reference). Of course, other types of immune cells that degranulate upon activation of the FcεRI signaling cascade may also be used, including, for example, eosinophils.

[0299] As will be recognized by skilled artisans, the mediator or agent quantified is not critical. The only requirement is that it be a mediator or agent released and/or synthesized as a consequence of initiating or activating the Fc receptor signaling cascade. For example, referring to FIG. 1, activation of the FcεRI signaling cascade in mast and/or basophil cells leads to numerous downstream events. For example, activation of the FcεRI signal cascade leads to the immediate release (i.e., within 1–3 min. following receptor activation) of a variety of preformed chemical mediators and agents via degranulation. Thus, in one embodiment, the mediator or agent quantified may be specific to granules (i.e., present in granules but not in the cell cytoplasm generally). Examples of granule-specific mediators or agents that can be quantified to determine and/or confirm the activity of a 2,4-pyrimidinediamine compound of the invention include, but are not limited to, granule-specific enzymes such as hexosaminidase and tryptase and granule-specific components such as histamine and serotonin. Assays for quantifying such factors are well-known, and in many instances are commercially available. For example, tryptase and/or hexosaminidase release may be quantified by incubating the cells with cleavable substrates that fluoresce upon cleavage and quantifying the amount of fluorescence produced using conventional techniques. Such cleavable fluorogenic substrates are commercially available. For example, the fluorogenic substrates Z-Gly-Pro-Arg-AMC (Z=benzyloxycarbonyl; AMC=7-amino-4-methylcoumarin; BIOMOL Research Laboratories, Inc., Plymouth Meeting, Pa. 19462, Catalog No. P-142) and Z-Ala-Lys-Arg-AMC (Enzyme Systems Products, a division of ICN Biomedicals, Inc., Livermore, Calif. 94550, Catalog No. AMC-246) can be used to quantify the amount of tryptase released. The fluorogenic substrate 4-methylumbelliferyl-N-acetyl-β-D-glucosaminide (Sigma, St. Louis, Mo., Catalog #69585) can be used to quantify the amount of hexosaminidase released. Histamine release may be quantified using a commercially available enzyme-linked immunosorbent assay (ELISA) such as Immunotech histamine ELISA assay #IM2015 (Beckman-Coulter, Inc.). Specific methods of quantifying the release of tryptase, hexosaminidase and histamine are provided in the Examples section. Any of these assays may be used to determine or confirm the activity of the 2,4-pyrimidinediamine compounds of the invention.

[0300] Referring again to FIG. 1, degranulation is only one of several responses initiated by the FcεRI signaling cascade. In addition, activation of this signaling pathway leads to the de novo synthesis and release of cytokines and chemokines such as IL-4, IL-5, IL-6, TNF-α, IL-13 and MIP1-α), and release of lipid mediators such as leukotrienes (e.g., LTC4), platelet activating factor (PAF) and prostaglandins. Accordingly, the 2,4-pyrimidinediamine compounds of the invention may also be assessed for activity by quantifying the amount of one or more of these mediators released and/or synthesized by activated cells.

[0301] Unlike the granule-specific components discussed above, these “late stage” mediators are not released immediately following activation of the FcεRI signaling cascade. Accordingly, when quantifying these late stage mediators, care should be taken to insure that the activated cell culture is incubated for a time sufficient to result in the synthesis (if necessary) and release of the mediator being quantified. Generally, PAF and lipid mediators such as leukotriene C4 are released 3–30 min. following FcεRI activation. The cytokines and other late stage mediators are released approx. 4–8 hrs. following FcεRI activation. Incubation times suitable for a specific mediator will be apparent to those of skill in the art. Specific guidance and assays are provided in the Examples section.

[0302] The amount of a particular late stage mediator released may be quantified using any standard technique. In one embodiment, the amount(s) may be quantified using ELISA assays. ELISA assay kits suitable for quantifying the amount of TNFα, IL-4, IL-5, IL-6 and/or IL-13 released are available from, for example, Biosource International, Inc., Camarillo, Calif. 93012 (see, e.g., Catalog Nos. KHC3011, KHC0042, KHC0052, KHC0061 and KHC0132). ELISA assay kits suitable for quantifying the amount of leukotriene C4 (LTC4) released from cells are available from Cayman Chemical Co., Ann Arbor, Mich. 48108 (see, e.g., Catalog No. 520211).

[0303] Typically, active 2,4-pyrimidinediamine compounds of the invention will exhibit IC₅₀s with respect to FcεRI-mediated degranulation and/or mediator release or synthesis of about 20 μM or lower, as measured in an in vitro assay, such as one of the in vitro assays described above or in the Examples section. Of course, skilled artisans will appreciate that compounds which exhibit lower IC₅₀s, for example on the order of 10 μM, 1 μM, 100 nM, 10 nM, 1 nM, or even lower, are particularly useful.

[0304] Skilled artisans will also appreciate that the various mediators discussed above may induce different adverse effects or exhibit different potencies with respect to the same adverse effect. For example, the lipid mediator LTC4 is a potent vasoconstrictor—it is approximately 1000-fold more potent at inducing vasoconstriction than histamine. As another example, in addition to mediating atopic or Type I hypersensitivity reactions, cytokines can also cause tissue remodeling and cell proliferation. Thus, although compounds that inhibit release and/or synthesis of any one of the previously discussed chemical mediators are useful, skilled artisans will appreciate that compounds which inhibit the release and/or synthesis of a plurality, or even all, of the previously described mediators find particular use, as such compounds are useful for ameliorating or avoiding altogether a plurality, or even all, of the adverse effects induced by the particular mediators. For example, compounds which inhibit the release of all three types of mediators—granule-specific, lipid and cytokine—are useful for treating or preventing immediate Type I hypersensitivity reactions as well as the chronic symptoms associated therewith.

[0305] Compounds of the invention capable of inhibiting the release of more than one type of mediator (e.g., granule-specific or late stage) may be identified by determining the IC₅₀ with respect to a mediator representative of each class using the various in vitro assays described above (or other equivalent in vitro assays). Compounds of the invention which are capable of inhibiting the release of more than one mediator type will typically exhibit an IC₅₀ for each mediator type tested of less than about 20 μM. For example, a compound which exhibits an IC₅₀ of 1 μM with respect to histamine release (IC₅₀^histamine) and an IC₅₀ of 1 nM with respect to leukotriene LTC4 synthesis and/or release (IC₅₀^LTC4) inhibits both immediate (granule-specific) and late stage mediator release. As another specific example, a compound that exhibits an IC₅₀^tryptase of 10 μM, an IC₅₀^LTC4 of 1 μM and an IC₅₀^IL-4 of 1 μM inhibits immediate (granule-specific), lipid and cytokine mediator release. Although the above specific examples utilize the IC₅₀s of one representative mediator of each class, skilled artisans will appreciate that the IC₅₀s of a plurality, or even all, mediators comprising one or more of the classes may be obtained. The quantity(ies) and identity(ies) of mediators for which IC₅₀ data should be ascertained for a particular compound and application will be apparent to those of skill in the art.

[0306] Similar assays may be utilized to confirm inhibition of signal transduction cascades initiated by other Fc receptors, such as FcαRI, FcγRI and/or FcγRIII signaling, with routine modification. For example, the ability of the compounds to inhibit FcγRI signal transduction may be confirmed in assays similar to those described above, with the exception that the FcγRI signaling cascade is activated, for example by incubating the cells with IgG and an IgG-specific allergen or antibody, instead of IgE and an IgE-specific allergen or antibody. Suitable cell types, activating agents and agents to quantify to confirm inhibition of other Fc receptors, such as Fc receptors that comprise a gamma homodimer, will be apparent to those of skill in the art.

[0307] One particularly useful class of compounds includes those 2,4-pyrimidinediamine compounds that inhibit the release of immediate granule-specific mediators and late stage mediators with approximately equivalent IC₅₀s. By approximately equivalent is meant that the IC₅₀s for each mediator type are within about a 10-fold range of one another. Another particularly useful class of compounds includes those 2,4-pyrimidinediamine compounds that inhibit the release of immediate granule-specific mediators, lipid mediators and cytokine mediators with approximately equivalent IC₅₀s. In a specific embodiment, such compounds inhibit the release of the following mediators with approximately equivalent IC₅₀s: histamine, tryptase, hexosaminidase, IL-4, IL-5, IL-6, IL-13, TNFα and LTC4. Such compounds are particularly useful for, among other things, ameliorating or avoiding altogether both the early and late stage responses associated with atopic or immediate Type I hypersensitivity reactions.

[0308] Ideally, the ability to inhibit the release of all desired types of mediators will reside in a single compound. However, mixtures of compounds can also be identified that achieve the same result. For example, a first compound which inhibits the release of granule specific mediators may be used in combination with a second compound which inhibits the release and/or synthesis of cytokine mediators.

[0309] In addition to the FcεRI or FcγRI degranulation pathways discussed above, degranulation of mast and/or basophil cells can be induced by other agents. For example, ionomycin, a calcium ionophore that bypasses the early FcεRI or FcγRI signal transduction machinery of the cell, directly induces a calcium flux that triggers degranulation. Referring again to FIG. 2, activated PLCγ initiates pathways that lead to, among other things, calcium ion mobilization and subsequent degranulation. As illustrated, this Ca²⁺ mobilization is triggered late in the FcεRI signal transduction pathway. As mentioned above, and as illustrated in FIG. 3, ionomycin directly induces Ca²⁺ mobilization and a Ca²⁺ flux that leads to degranulation. Other ionophores that induce degranulation in this manner include A23187. The ability of granulation-inducing ionophores such as ionomycin to bypass the early stages of the FcεRI and/or FcγRI signaling cascades may be used as a counter screen to identify active compounds of the invention that specifically exert their degranulation-inhibitory activity by blocking or inhibiting the early FcεRI or FcγRI signaling cascades, as discussed above. Compounds which specifically inhibit such early FcεRI or FcγRI-mediated degranulation inhibit not only degranulation and subsequent rapid release of histamine, tryptase and other granule contents, but also inhibit the pro-inflammatory activation pathways causing the release of TNFα, IL-4, IL-13 and the lipid mediators such as LTC4. Thus, compounds which specifically inhibit such early FcεRI and/or FcγRI-mediated degranulation block or inhibit not only acute atopic or Type I hypersensitivity reactions, but also late responses involving multiple inflammatory mediators.

[0310] Compounds of the invention that specifically inhibit early FcεRI and/or FcγRI-mediated degranulation are those compounds that inhibit FcεRI and/or FcγRI-mediated degranulation (for example, have an IC₅₀ of less than about 20 μM with respect to the release of a granule-specific mediator or component as measured in an in vitro assay with cells stimulated with an IgE or IgG binding agent) but that do not appreciably inhibit ionophore-induced degranulation. In one embodiment, compounds are considered to not appreciably inhibit ionophore-induced degranulation if they exhibit an IC₅₀ of ionophore-induced degranulation of greater than about 20 μM, as measured in an in vitro assay. Of course, active compounds that exhibit even higher IC₅₀s of ionophore-induced degranulation, or that do not inhibit ionophore-induced degranulation at all, are particularly useful. In another embodiment, compounds are considered to not appreciably inhibit ionophore-induced degranulation if they exhibit a greater than 10-fold difference in their IC₅₀s of FcεRI and/or FcγRI-mediated degranulation and ionophore-induced degranulation, as measured in an in vitro assay. Assays suitable for determining the IC₅₀ of ionophore-induced degranulation include any of the previously-described degranulation assays, with the modification that the cells are stimulated or activated with a degranulation-inducing calcium ionophore such as ionomycin or A23187 (A.G. Scientific, San Diego, Calif.) instead of anti-IgE antibodies or an IgE-specific allergen. Specific assays for assessing the ability of a particular 2,4-pyrimidinediamine compound of the invention to inhibit ionophore-induced degranulation are provided in the Examples section.

[0311] As will be recognized by skilled artisans, compounds which exhibit a high degree of selectivity of FcεRI-mediated degranulation find particular use, as such compounds selectively target the FcεRI cascade and do not interfere with other degranulation mechanisms. Similarly, compounds which exhibit a high degree of selectivity of FcγRI-mediated degranulation find particular use, as such compounds selectively target the FcγRI cascade and do not interfere with other degranulation mechanisms. Compounds which exhibit a high degree of selectivity are generally 10-fold or more selective for FcεRI- or FcγRI -mediated degranulation over ionophore-induced degranulation, such as ionomycin-induced degranulation.

[0312] Biochemical and other data confirm that the 2,4-pyrimidinediamine compounds described herein are potent inhibitors of Syk kinase activity. For example, in experiments with an isolated Syk kinase, of twenty four 2,4-pyrimidinediamine compounds tested, all but two inhibited the Syk kinase catalyzed phosphorylation of a peptide substrate with IC50s in the submicromolar range. The remaining compounds inhibited phosphorylation in the micromolar range. In addition, of sixteen compounds tested in an in vitro assay with mast cells, all inhibited phosphorylation of Syk kinase substrates (e.g., PLC-gamma1, LAT) and proteins downstream of Syk kinase (e.g., JNK, p38, Erk1/2 and PKB, when tested), but not proteins upstream of Syk kinase in the cascade (e.g., Lyn). Phosphorylation of Lyn substrates was not inhibited by the 2,4-pyrimidinediamine compounds tested. Moreover, for the following compounds, a high correlation was observed between their inhibition of Syk kinase activity in biochemical assays (IC₅₀s in the range of 3 to 1850 nM) and their inhibition of FcεR1-mediated degranulation in mast cells (IC₅₀s in the range of 30 to 1650 nM): R950373, R950368, R921302, R945371, R945370, R945369, R945365, R921304, R945144, R945140, R945071, R940358, R940353, R940352, R940351, R940350, R940347, R921303, R940338, R940323, R940290, R940277, R940276, R940275, R940269, R940255, R935393, R935372, R935366, R935310, R935309, R935307, R935304, R935302, R935293, R935237, R935198, R935196, R935194, R935193, R935191, R935190, R935138, R927050, R926968, R926956, R926931, R926891, R926839, R926834, R926816, R926813, R926791, R926782, R926780, R926757, R926753, R926745, R926715, R926508, R926505, R926502, R926501, R926500, R921218, R921147, R920410, R909268, R921219, R908712, R908702.

[0313] Accordingly, the activity of the 2,4-pyrimidinediamine compounds of the invention may also be confirmed in biochemical or cellular assays of Syk kinase activity. Referring again to FIG. 2, in the FcεRI signaling cascade in mast and/or basophil cells, Syk kinase phosphorylates LAT and PLC-gamma1, which leads to, among other things, degranulation. Any of these activities may be used to confirm the activity of the 2,4-pyrimidinediamine compounds of the invention. In one embodiment, the activity is confirmed by contacting an isolated Syk kinase, or an active fragment thereof with a 2,4-pyrimidinediamine compound in the presence of a Syk kinase substrate (e.g., a synthetic peptide or a protein that is known to be phophorylated by Syk in a signaling cascade) and assessing whether the Syk kinase phosphorylated the substrate. Alternatively, the assay may be carried out with cells that express a Syk kinase. The cells may express the Syk kinase endogenously or they may be engineered to express a recombinant Syk kinase. The cells may optionally also express the Syk kinase substrate. Cells suitable for performing such confirmation assays, as well as methods of engineering suitable cells will be apparent to those of skill in the art. Specific examples of biochemical and cellular assays suitable for confirming the activity of the 2,4-pyrimidinediamine compounds are provided in the Examples section.

[0314] Generally, compounds that are Syk kinase inhibitors will exhibit an IC₅₀ with respect to a Syk kinase activity, such as the ability of Syk kinase to phosphorylate a synthetic or endogenous substrate, in an in vitro or cellular assay in the range of about 20 μM or less. Skilled artisans will appreciate that compounds that exhibit lower IC50s, such as in the range of 10 μM, 100 nM, 10 nM, 1 nM, or even lower, are particularly useful.

[0315] 6.5 Uses and Compositions

[0316] As previously discussed, the active compounds of the invention inhibit Fc receptor signaling cascades, especially those Fc receptors including a gamma homodimer, such as the FcεRI and/or FcγRI signaling cascades, that lead to, among other things, the release and/or synthesis of chemical mediators from cells, either via degranulation or other processes. As also discussed, the active compounds are also potent inhibitors of Syk kinase. As a consequence of these activities, the active compounds of the invention may be used in a variety of in vitro, in vivo and ex vivo contexts to regulate or inhibit Syk kinase, signaling cascades in which Syk kinase plays a role, Fc receptor signaling cascades, and the biological responses effected by such signaling cascades. For example, in one embodiment, the compounds may be used to inhibit Syk kinase, either in vitro or in vivo, in virtually any cell type expressing Syk kinase. They may also be used to regulate signal transduction cascades in which Syk kinase plays a role. Such Syk-dependent signal transduction cascades include, but are not limited to, the FcεRI, FcγRI, FcγRIII, BCR and integrin signal transduction cascades. The compounds may also be used in vitro or in vivo to regulate, and in particular inhibit, cellular or biological responses effected by such Syk-dependent signal transduction cascades. Such cellular or biological responses include, but are not limited to, respiratory burst, cellular adhesion, cellular degranulation, cell spreading, cell migration, cell aggregation, phagcytosis, cytokine synthesis and release, cell maturation and Ca²⁺ flux. Importantly, the compounds may be used to inhibit Syk kinase in vivo as a therapeutic approach towards the treatment or prevention of diseases mediated, either wholly or in part, by a Syk kinase activity. Non-limiting examples of Syk kinase mediated diseases that may be treated or prevented with the compounds are those discussed in more detail, below.

[0317] In another embodiment, the active compounds may be used to regulate or inhibit the Fc receptor signaling cascades and/or FcεRI- and/or FcγRI-mediated degranulation as a therapeutic approach towards the treatment or prevention of diseases characterized by, caused by and/or associated with the release or synthesis of chemical mediators of such Fc receptor signaling cascades or degranulation. Such treatments may be administered to animals in veterinary contexts or to humans. Diseases that are characterized by, caused by or associated with such mediator release, synthesis or degranulation, and that can therefore be treated or prevented with the active compounds include, by way of example and not limitation, atopy or anaphylactic hypersensitivity or allergic reactions, allergies (e.g., allergic conjunctivitis, allergic rhinitis, atopic asthma, atopic dermatitis and food allergies), low grade scarring (e.g., of scleroderma, increased fibrosis, keloids, post-surgical scars, pulmonary fibrosis, vascular spasms, migraine, reperfusion injury and post myocardial infarction), diseases associated with tissue destruction (e.g., of COPD, cardiobronchitis and post myocardial infarction), diseases associated with tissue inflammation (e.g., irritable bowel syndrome, spastic colon and inflammatory bowel disease), inflammation and scarring.

[0318] When used to treat or prevent such diseases, the active compounds may be administered singly, as mixtures of one or more active compounds or in mixture or combination with other agents useful for treating such diseases and/or the symptoms associated with such diseases. The active compounds may also be administered in mixture or in combination with agents useful to treat other disorders or maladies, such as steroids, membrane stablizers, 5LO inhibitors, leukotriene synthesis and receptor inhibitors, inhibitors of IgE isotype switching or IgE synthesis, IgG isotype switching or IgG synthesis, β-agonists, tryptase inhibitors, aspirin, COX inhibitors, methotrexate, anti-TNF drugs, retuxin, PD4 inhibitors, p38 inhibitors, PDE4 inhibitors, and antihistamines, to name a few. The active compounds may be administered per se in the form of prodrugs or as pharmaceutical compositions, comprising an active compound or prodrug.

[0319] Pharmaceutical compositions comprising the active compounds of the invention (or prodrugs thereof) may be manufactured by means of conventional mixing, dissolving, granulating, dragee-making levigating, emulsifying, encapsulating, entrapping or lyophilization processes. The compositions may be formulated in conventional manner using one or more physiologically acceptable carriers, diluents, excipients or auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically.

[0320] The active compound or prodrug may be formulated in the pharmaceutical compositions per se, or in the form of a hydrate, solvate, N-oxide or pharmaceutically acceptable salt, as previously described. Typically, such salts are more soluble in aqueous solutions than the corresponding free acids and bases, but salts having lower solubility than the corresponding free acids and bases may also be formed.

[0321] Pharmaceutical compositions of the invention may take a form suitable for virtually any mode of administration, including, for example, topical, ocular, oral, buccal, systemic, nasal, injection, transdermal, rectal, vaginal, etc., or a form suitable for administration by inhalation or insufflation.

[0322] For topical administration, the active compound(s) or prodrug(s) may be formulated as solutions, gels, ointments, creams, suspensions, etc. as are well-known in the art.

[0323] Systemic formulations include those designed for administration by injection, e.g., subcutaneous, intravenous, intramuscular, intrathecal or intraperitoneal injection, as well as those designed for transdermal, transmucosal oral or pulmonary administration.

[0324] Useful injectable preparations include sterile suspensions, solutions or emulsions of the active compound(s) in aqueous or oily vehicles. The compositions may also contain formulating agents, such as suspending, stabilizing and/or dispersing agent. The formulations for injection may be presented in unit dosage form, e.g., in ampules or in multidose containers, and may contain added preservatives.

[0325] Alternatively, the injectable formulation may be provided in powder form for reconstitution with a suitable vehicle, including but not limited to sterile pyrogen free water, buffer, dextrose solution, etc., before use. To this end, the active compound(s) may be dried. by any art-known technique, such as lyophilization, and reconstituted prior to use.

[0326] For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are known in the art.

[0327] For oral administration, the pharmaceutical compositions may take the form of, for example, lozenges, tablets or capsules prepared by conventional means with pharmaceutically acceptable excipients such as binding agents (e.g., pregelatinised maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose); fillers (e.g., lactose, microcrystalline cellulose or calcium hydrogen phosphate); lubricants (e.g., magnesium stearate, talc or silica); disintegrants (e.g., potato starch or sodium starch glycolate); or wetting agents (e.g., sodium lauryl sulfate). The tablets may be coated by methods well known in the art with, for example, sugars, films or enteric coatings. Compounds which are particularly suitable for oral administration include Compounds R940350, R935372, R935193, R927050 and R935391.

[0328] Liquid preparations for oral administration may take the form of, for example, elixirs, solutions, syrups or suspensions, or they may be presented as a dry product for constitution with water or other suitable vehicle before use. Such liquid preparations may be prepared by conventional means with pharmaceutically acceptable additives such as suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, ethyl alcohol, cremophore™ or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p-hydroxybenzoates or sorbic acid). The preparations may also contain buffer salts, preservatives, flavoring, coloring and sweetening agents as appropriate.

[0329] Preparations for oral administration may be suitably formulated to give controlled release of the active compound or prodrug, as is well known.

[0330] For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner.

[0331] For rectal and vaginal routes of administration, the active compound(s) may be formulated as solutions (for retention enemas) suppositories or ointments containing conventional suppository bases such as cocoa butter or other glycerides.

[0332] For nasal administration or administration by inhalation or insufflation, the active compound(s) or prodrug(s) can be conveniently delivered in the form of an aerosol spray from pressurized packs or a nebulizer with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, fluorocarbons, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges for use in an inhaler or insufflator (for example capsules and cartridges comprised of gelatin) may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.

[0333] A specific example of an aqueous suspension formulation suitable for nasal administration using commercially-available nasal spray devices includes the following ingredients: active compound or prodrug (0.5–20 mg/ml); benzalkonium chloride (0.1–0.2 mg/mL); polysorbate 80 (TWEEN® 80; 0.5–5 mg/ml); carboxymethylcellulose sodium or microcrystalline cellulose (1–15 mg/ml); phenylethanol (14 mg/ml); and dextrose (20–50 mg/ml). The pH of the final suspension can be adjusted to range from about pH5 to pH7, with a pH of about pH 5.5 being typical.

[0334] Another specific example of an aqueous suspension suitable for administration of the compounds via inhalation, and in particular for such administration of Compound R921218, contains 1–20 mg/mL Compound or prodrug, 0.1–1% (v/v) Polysorbate 80 (TWEEN®80), 50 mM citrate and/or 0.9% sodium chloride.

[0335] For ocular administration, the active compound(s) or prodrug(s) may be formulated as a solution, emulsion, suspension, etc. suitable for administration to the eye. A variety of vehicles suitable for administering compounds to the eye are known in the art. Specific non-limiting examples are described in U.S. Pat. Nos. 6,261,547; 6,197,934; 6,056,950; 5,800,807; 5,776,445; 5,698,219; 5,521,222; 5,403,841; 5,077,033; 4,882,150; and 4,738,851.

[0336] For prolonged delivery, the active compound(s) or prodrug(s) can be formulated as a depot preparation for administration by implantation or intramuscular injection. The active ingredient may be formulated with suitable polymeric or hydrophobic materials (e.g., as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, e.g., as a sparingly soluble salt. Alternatively, transdermal delivery systems manufactured as an adhesive disc or patch which slowly releases the active compound(s) for percutaneous absorption may be used. To this end, permeation enhancers may be used to facilitate transdermal penetration of the active compound(s). Suitable transdermal patches are described in for example, U.S. Pat. Nos. 5,407,713.; 5,352,456; 5,332,213; 5,336,168; 5,290,561; 5,254,346; 5,164,189; 5,163,899; 5,088,977; 5,087,240; 5,008,110; and 4,921,475.

[0337] Alternatively, other pharmaceutical delivery systems may be employed. Liposomes and emulsions are well-known examples of delivery vehicles that may be used to deliver active compound(s) or prodrug(s). Certain organic solvents such as dimethylsulfoxide (DMSO) may also be employed, although usually at the cost of greater toxicity.

[0338] The pharmaceutical compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active compound(s). The pack may, for example, comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration.

[0339] 6.6 Effective Dosages

[0340] The active compound(s) or prodrug(s) of the invention, or compositions thereof, will generally be used in an amount effective to achieve the intended result, for example in an amount effective to treat or prevent the particular disease being treated. The compound(s) may be administered therapeutically to achieve therapeutic benefit or prophylactically to achieve prophylactic benefit. By therapeutic benefit is meant eradication or amelioration of the underlying disorder being treated and/or eradication or amelioration of one or more of the symptoms associated with the underlying disorder such that the patient reports an improvement in feeling or condition, notwithstanding that the patient may still be afflicted with the underlying disorder. For example, administration of a compound to a patient suffering from an allergy provides therapeutic benefit not only when the underlying allergic response is eradicated or ameliorated, but also when the patient reports a decrease in the severity or duration of the symptoms associated with the allergy following exposure to the allergen. As another example, therapeutic benefit in the context of asthma includes an improvement in respiration following the onset of an asthmatic attack, or a reduction in the frequency or severity of asthmatic episodes. Therapeutic benefit also includes halting or slowing the progression of the disease, regardless of whether improvement is realized.

[0341] For prophylactic administration, the compound may be administered to a patient at risk of developing one of the previously described diseases. For example, if it is unknown whether a patient is allergic to a particular drug, the compound may be administered prior to administration of the drug to avoid or ameliorate an allergic response to the drug. Alternatively, prophylactic administration may be applied to avoid the onset of symptoms in a patient diagnosed with the underlying disorder. For example, a compound may be administered to an allergy sufferer prior to expected exposure to the allergen. Compounds may also be administered prophylactically to healthy individuals who are repeatedly exposed to agents known to one of the above-described maladies to prevent the onset of the disorder. For example, a compound may be administered to a healthy individual who is repeatedly exposed to an allergen known to induce allergies, such as latex, in an effort to prevent the individual from developing an allergy. Alternatively, a compound may be administered to a patient suffering from asthma prior to partaking in activities which trigger asthma attacks to lessen the severity of, or avoid altogether, an asthmatic episode.

[0342] The amount of compound administered will depend upon a variety of factors, including, for example, the particular indication being treated, the mode of administration, whether the desired benefit is prophylactic or therapeutic, the severity of the indication being treated and the age and weight of the patient, the bioavailability of the particular active compound, etc. Determination of an effective dosage is well within the capabilities of those skilled in the art.

[0343] Effective dosages may be estimated initially from in vitro assays. For example, an initial dosage for use in animals may be formulated to achieve a circulating blood or serum concentration of active compound that is at or above an IC₅₀ of the particular compound as measured in as in vitro assay, such as the in vitro CHMC or BMMC and other in vitro assays described in the Examples section. Calculating dosages to achieve such circulating blood or serum concentrations taking into account the bioavailability of the particular compound is well within the capabilities of skilled artisans. For guidance, the reader is referred to Fingl & Woodbury, “General Principles,” In: Goodman and Gilman's The Pharmaceutical Basis of Therapeutics, Chapter 1, pp. 146, latest edition, Pagamonon Press, and the references cited therein.

[0344] Initial dosages can also be estimated from in vivo data, such as animal models. Animal models useful for testing the efficacy of compounds to treat or prevent the various diseases described above are well-known in the art. Suitable animal models of hypersensitivity or allergic reactions are described in Foster, 1995, Allergy 50(21Suppl):6–9, discussion 34–38 and Tumas et al., 2001, J. Allergy Clin. Immunol. 107(6):1025–1033. Suitable animal models of allergic rhinitis are described in Szelenyi et al., 2000, Arzneimittelforschung 50(11):1037–42; Kawaguchi et al., 1994, Clin. Exp. Allergy 24(3):238–244 and Sugimoto et al., 2000, Immunopharmacology 48(1):1–7. Suitable animal models of allergic conjunctivitis are described in Carreras et al., 1993, Br. J. Ophthalmol. 77(8):509–514; Saiga et al., 1992, Ophthalmic Res. 24(1):45–50; and Kunert et al., 2001, Invest. Ophthalmol. Vis. Sci. 42(11):2483–2489. Suitable animal models of systemic mastocytosis are described in O'Keefe et al., 1987, J. Vet. Intern. Med. 1(2):75–80 and Bean-Knudsen et al., 1989, Vet. Pathol. 26(1):90–92. Suitable animal models of hyper IgE syndrome are described in Claman et al., 1990, Clin. Immunol. Immunopathol. 56(1):46–53. Suitable animal models of B-cell lymphoma are described in Hough et al., 1998, Proc. Natl. Acad. Sci. USA 95:13853–13858 and Hakim et al., 1996, J. Immunol. 157(12):5503–5511. Suitable animal models of atopic disorders such as atopic dermatitis, atopic eczema and atopic asthma are described in Chan et al., 2001, J. Invest. Dermatol. 117(4):977–983 and Suto et al., 1999, Int. Arch. Allergy Immunol. 120(Suppl 1):70–75. Ordinarily skilled artisans can routinely adapt such information to determine dosages suitable for human administration. Additional suitable animal models are described in the Examples section.

[0345] Dosage amounts will typically be in the range of from about 0.0001 or 0.001 or 0.01 mg/kg/day to about 100 mg/kg/day, but may be higher or lower, depending upon, among other factors, the activity of the compound, its bioavailability, the mode of administration and various factors discussed above. Dosage amount and interval may be adjusted individually to provide plasma levels of the compound(s) which are sufficient to maintain therapeutic or prophylactic effect. For example, the compounds may be administered once per week, several times per week (e.g., every other day), once per day or multiple times per day, depending upon, among other things, the mode of administration, the specific indication being treated and the judgment of the prescribing physician. In cases of local administration or selective uptake, such as local topical administration, the effective local concentration of active compound(s) may not be related to plasma concentration. Skilled artisans will be able to optimize effective local dosages without undue experimentation.

[0346] Preferably, the compound(s) will provide therapeutic or prophylactic benefit without causing substantial toxicity. Toxicity of the compound(s) may be determined using standard pharmaceutical procedures. The dose ratio between toxic and therapeutic (or prophylactic) effect is the therapeutic index. Compounds(s) that exhibit high therapeutic indices are preferred.
