Description
[0003] This application claims the benefit of U.S. Provisional Application No. 60/068,491, filed Dec. 22, 1997 and U.S. Provisional Application No. 60/101,075, filed Sep. 18, 1998.
FIELD OF THE INVENTION
[0004] This invention relates generally to nitrogen containing heteroaromatics, with ortho-substituted P1 groups, which are inhibitors of trypsin-like serine protease enzymes, especially factor Xa, pharmaceutical compositions containing the same, and methods of using the same as anticoagulant agents for treatment and prevention of thromboembolic disorders.
BACKGROUND OF THE INVENTION
[0005] WO 95/18111 addresses fibrinogen receptor antagonists, containing basic and acidic termini, of the formula:
[0006] wherein R1represents the basic termini, U is an alkylene or heteroatom linker, V may be a heterocycle, and the right hand portion of the molecule represents the acidic termini. The presently claimed compounds do not contain the acidic termini of WO 95/18111.
[0007] In U.S. Pat. No. 5,463,071, Himmelsbach et al depict cell aggregation inhibitors which are 5-membered heterocycles of the formula:
[0008] wherein the heterocycle may be aromatic and groups A—B—C— and F—E—D— are attached to the ring system. A—B—C— can be a wide variety of substituents including a basic group attached to an aromatic ring. The F—E—D— group, however, would appear to be an acidic functionality which differs from the present invention. Furthermore, use of these compounds as inhibitors of factor Xa is not discussed.
[0009] Baker et al, in U.S. Pat. No. 5,317,103, discuss 5-HT1agonists which are indole substituted five-membered heteroaromatic compounds of the formula:
[0010] wherein R1may be pyrrolidine or piperidine and A may be a basic group including amino and amidino. Baker et al, however, do not indicate that A can be a substituted ring system like that contained in the presently claimed heteroaromatics.
[0011] Baker et al, in WO 94/02477, discuss 5-HT1agonists which are imidazoles, triazoles, or tetrazoles of the formula:
[0012] wherein R1represents a nitrogen containing ring system or a nitrogen substituted cyclobutane, and A may be a basic group including amino and amidino. Baker et al, however, do not indicate that A can be a substituted ring system like that contained in the presently claimed heteroaromatics.
[0013] Illig et al, in WO 97/47299, illustrate amidino and guanidino heterocycle protease inhibitors of the formula:
[0014] R1—Z—X—Y—W
[0015] wherein R1can be a substituted aryl group, Z is a two carbon linker containing at least one heteroatome, X is a heterocycle, Y is an optional linker and W is an amidino or guanidino containing group. Compounds of this sort are not considered part of the present invention.
[0016] Jackson et al, in WO 97/32583, describe cytokine inhibitors useful for inhibiting angiogenesis. These inhibitors include imidazoles of the formula:
[0017] wherein R1is a variety of heteroaryl groups, R4is phenyl, naphthyl, or a heteroaryl group, and R2can be a wide variety of groups. Jackson et al do not teach inhibition of factor Xa. Furthermore, the imidazoles of Jackson et al are not considered part of the present invention.
[0018] Activated factor Xa, whose major practical role is the generation of thrombin by the limited proteolysis of prothrombin, holds a central position that links the intrinsic and extrinsic activation mechanisms in the final common pathway of blood coagulation. The generation of thrombin, the final serine protease in the pathway to generate a fibrin clot, from its precursor is amplified by formation of prothrombinase complex (factor Xa, factor V, Ca2+and phospholipid). Since it is calculated that one molecule of factor Xa can generate 138 molecules of thrombin (Elodi, S., Varadi, K.: Optimization of conditions for the catalytic effect of the factor IXa-factor VIII Complex: Probable role of the complex in the amplification of blood coagulation. Thromb. Res.1979, 15, 617-629), inhibition of factor Xa may be more efficient than inactivation of thrombin in interrupting the blood coagulation system.
[0019] Therefore, efficacious and specific inhibitors of factor Xa are needed as potentially valuable therapeutic agents for the treatment of thromboembolic disorders. It is thus desirable to discover new factor Xa inhibitors.
SUMMARY OF THE INVENTION
[0020] Accordingly, one object of the present invention is to provide novel nitrogen containing aromatic heterocycles, with ortho-substituted P1 groups, which are useful as factor Xa inhibitors or pharmaceutically acceptable salts or prodrugs thereof.
[0021] It is another object of the present invention to provide pharmaceutical compositions comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof.
[0022] It is another object of the present invention to provide a method for treating thromboembolic disorders comprising administering to a host in need of such treatment a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof.
[0023] These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors' discovery that compounds of formula (I):
[0024] or pharmaceutically acceptable salt or prodrug forms thereof, wherein A, B, D, E, G, J, M, R1a, R1b, and s are defined below, are effective factor Xa inhibitors.

DEFINITIONS
[0340] The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated. All processes used to prepare compounds of the present invention and intermediates made therein are considered to be part of the present invention.
[0341] The term “substituted,” as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substitent is keto (i.e., ═O), then 2 hydrogens on the atom are replaced. Keto substituents are not present on aromatic moieties.
[0342] The present invention is intended to include all isotopes of atoms occurring in the present compounds. Isotopes include those atoms having the same atomic number but different mass numbers. By way of general example and without limitation, isotopes of hydrogen include tritium and deuterium. Isotopes of carbon include C-13 and C-14.
[0343] When any variable (e.g., R6) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 R6, then said group may optionally be substituted with up to two R6groups and R6at each occurrence is selected independently from the definition of R6. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
[0344] When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
[0345] As used herein, “alkyl” is intended to include both branched and straight-chain saturated aliphatic hydrocarbon groups having the specified number of carbon atoms. Examples of alkyl include, but are not limited to, methyl, ethyl, n-propyl, i-propyl, n-butyl, s-butyl, t-butyl, n-pentyl, and s-pentyl. “Haloalkyl” is intended to include both branched and straight-chain saturated aliphatic hydrocarbon groups having the specified number of carbon atoms, substituted with 1 or more halogen (for example −CvFwwhere v=1 to 3 and w=1 to (2v+1)). Examples of haloalkyl include, but are not limited to, trifluoromethyl, trichloromethyl, pentafluoroethyl, and pentachloroethyl. “Alkoxy” represents an alkyl group as defined above with the indicated number of carbon atoms attached through an oxygen bridge. Examples of alkoxy include, but are not limited to, methoxy, ethoxy, n-propoxy, i-propoxy, n-butoxy, s-butoxy, t-butoxy, n-pentoxy, and s-pentoxy. “Cycloalkyl” is intended to include saturated ring groups, such as cyclopropyl, cyclobutyl, or cyclopentyl. Alkenyl” is intended to include hydrocarbon chains of either a straight or branched configuration and one or more unsaturated carbon-carbon bonds which may occur in any stable point along the chain, such as ethenyl and propenyl. “Alkynyl” is intended to include hydrocarbon chains of either a straight or branched configuration and one or more triple carbon-carbon bonds which may occur in any stable point along the chain, such as ethynyl and propynyl.
[0346] “Halo” or “halogen” as used herein refers to fluoro, chloro, bromo, and iodo; and “counterion” is used to represent a small, negatively charged species such as chloride, bromide, hydroxide, acetate, and sulfate.
[0347] As used herein, “carbocycle” or “carbocyclic residue” is intended to mean any stable 3- to 7-membered monocyclic or bicyclic or 7-to 13-membered bicyclic or tricyclic, any of which may be saturated, partially unsaturated, or aromatic. Examples of such carbocycles include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, adamantyl, cyclooctyl, [3.3.0]bicyclooctane, [4.3.0]bicyclononane, [4.4.0]bicyclodecane, [2.2.2]bicyclooctane, fluorenyl, phenyl, naphthyl, indanyl, adamantyl, and tetrahydronaphthyl.
[0348] As used herein, the term “heterocycle” or “heterocyclic system” is intended to mean a stable 5-to 7-membered monocyclic or bicyclic or 7-to 10-membered bicyclic heterocyclic ring which is saturated partially unsaturated or unsaturated (aromatic), and which consists of carbon atoms and from 1 to 4 heteroatoms independently selected from the group consisting of N, O and S and including any bicyclic group in which any of the above-defined heterocyclic rings is fused to a benzene ring. The nitrogen and sulfur heteroatoms may optionally be oxidized. The heterocyclic ring may be attached to its pendant group at any heteroatom or carbon atom which results in a stable structure. The heterocyclic rings described herein may be substituted on carbon or on a nitrogen atom if the resulting compound is stable. A nitrogen in the heterocycle may optionally be quaternized. It is preferred that when the total number of S and O atoms in the heterocycle exceeds 1, then these heteroatoms are not adjacent to one another. It is preferred that the total number of S and O atoms in the heterocycle is not more than 1. As used herein, the term “aromatic heterocyclic system” or “heteroaryl” is intended to mean a stable 5-to 7-membered monocyclic or bicyclic or 7-to 10-membered bicyclic heterocyclic aromatic ring which consists of carbon atoms and from 1 to 4 heterotams independently selected from the group consisting of N, O and S. It is preferred that the total number of S and O atoms in the aromatic heterocycle is not more than 1.

For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.
[0352] The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences,17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418, the disclosure of which is hereby incorporated by reference.
[0353] “Prodrugs” are intended to include any covalently bonded carriers which release the active parent drug according to formula (I) in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of formula (I) are prepared by modifying functional groups present in the compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound. Prodrugs include compounds of formula (I) wherein a hydroxy, amino, or sulfhydryl group is bonded to any group that, when the prodrug or compound of formula (I) is administered to a mammalian subject, cleaves to form a free hydroxyl, free amino, or free sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of alcohol and amine functional groups in the compounds of formula (I), and the like. Preferred prodrugs are amidine prodrugs wherein D is C(═NR7)NH2or its tautomer C(═NH)NHR7and R7is selected from OH, C1-4alkoxy, C6-10aryloxy, C1-4alkoxycarbonyl, C6-10aryloxycarbonyl, C6-10arylmethylcarbonyl, C1-4alkylcarbonyloxy C1-4alkoxycarbonyl, and C6-10arylcarbonyloxy C1-4alkoxycarbonyl. More preferred prodrugs are where R7is OH, methoxy, ethoxy, benzyloxycarbonyl, methoxycarbonyl, and methylcarbonyloxymethoxycarbonyl.

[0355] “Substituted” is intended to indicate that one or more hydrogens on the atom indicated in the expression using “substituted” is replaced with a selection from the indicated group(s), provided that the indicated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substituent is keto (i.e., ═O) group, then 2 hydrogens on the atom are replaced.
[0356] “Therapeutically effective amount” is intended to include an amount of a compound of the present invention or an amount of the combination of compounds claimed effective to inhibit HIV infection or treat the symptoms of HIV infection in a host. The combination of compounds is preferably a synergistic combination. Synergy, as described for example by Chou and Talalay, Adv. Enzyme Regul.22:27-55 (1984), occurs when the effect (in this case, inhibition of HIV replication) of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at suboptimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased antiviral effect, or some other beneficial effect of the combination compared with the individual components.

[0357] The compounds of the present invention can be prepared in a number of ways known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed.

It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic Synthesis, Wiley and Sons, 1991). All references cited herein are hereby incorporated in their entirety herein by reference.
[0358] The compounds of Formula I in which ring M is pyrrole can be prepared by the procedures described in Schemes 1-9. In Scheme 1 is shown how to prepare pyrroles in which the group Q—E is attached to the pyrrole nitrogen, wherein Q is a functionality that can be converted into D of Formula I, Re is functionality that can be converted into Z—A—B of Formula I and Rfis or can be converted into R1aof Formula I. Oxidation of a furan with bromine in acetic acid can afford a 2,5-diacetoxydihydrofuran which can react with amine Q—E—NH2 to afford a pyrrole. Vilsmeier-Haack formulation with phosphorous oxychloride and DMF preferentially can acylate the pyrrole ring at C-2. Oxidation of the resulting aldehyde can give a carboxylic acid. The carboxylic acid can then be converted into amine derivatives using either the Hofmann degradation of the derived primary amide (Huisgen et. al. Chem. Ber.1960, 93, 65) or the Curtius rearrangement of the derived acyl azide (J. Prakt. Chem.1909, 42, 477). Derivatives which contain a sulfur atom attached to the pyrrole ring can be obtained by direct sulfonation with pyridine sulfur trioxide complex to give the sulfonic acids or treatment with copper (II) thiocyanate (J. Het. Chem.1988, 25, 431) followed by the reduction of the intermediate thiocyanate with sodium borohydride to give a mercaptan.
[0359] In Scheme 2 is shown how to prepare pyrroles in which Q—E is attached to the 2-position, wherein Rfand Rgcollectively are hydrogen or a group that can be converted into R1aand R1bof Formula I. The Hantzsch pyrrole synthesis is a versatile reaction involving the cyclization of an appropriate β-ketoester with an α-halo ketone or aldehyde in the presence of a primary amine (Ber. Dtsch Chem. Ges.1890, 23, 1474). The β-ketoesters can be prepared from acid chlorides (X═Cl) by the addition of the magnesium anion of potassium alkylmalonate followed by decarboxylation (Synthesis1993, 290). Alternatively, β-ketoesters can be prepared from an appropriate aldehyde (R═H) by Reformatsky reaction with an α-bromoacetate followed by oxidation. Cyclization with an α-halo ketone or aldehyde in the presence of a primary amine can afford pyrroles. Acidic hydrolysis of the 3-carboalkoxy pyrrole can afford the carboxylic acids. Pyrroles which contain a 3-amino substituent can be prepared from the acids by treatment with phosphoryl azide and triethylamine to effect a Curtius rearrangement to afford the isocyanates (J. Med. Chem.1981, 24, 33) which upon hydrolysis can yield 3-aminopyrroles. Pyrroles which contain a sulfur atom at C-3 can be prepared from the acids by employing the Hunsdiecker procedure to give the 3-bromo derivatives. Halogen-metal exchange at low temperature with an alkyllithium reagent can afford the 3-lithio derivative which can be quenched with a variety of electrophiles, such as S8 to afford thiols directly or Cu(SCN)2to afford a thiocyanate which can be reduced with sodium borohydride. The thiols can further be oxidized to the sulfonic acid derivatives by an oxidant such as KMnO4.
[0360] In Scheme 3 is shown how to prepare pyrroles in which Q—E is attached to the 3-position. This scheme relies upon the extremely versatile Knorr pyrrole synthesis, which involves condensation of α-aminoketones with β-ketoesters. The α-aminoketones can be prepared from β-ketoesters (Scheme 2) by nitrosation followed by reduction with zinc/acetic acid. Condensation of α-aminoketones with appropriate β-ketoesters can afford good yields of pyrroles. These intermediates are very versatile and can be converted into pyrroles with a wide variety of substituents with varying substitution patterns. For cases wherein Re(Z—A—B precursor) is at the 2-position, acidic hydrolysis can selectively hydrolyze the C-3 ester. Heating should then effect decarboxylation. Hydrolysis of the 2-carboxylic acid can be achieved under basic conditions. Curtius rearrangement of the acid as described previously can afford the amino derivatives. To prepare compounds with a sulfur atom attached to C-2, basic hydrolysis and decarboxylation can afford the C-2 unsubstituted pyrroles. These pyrroles can undergo electrophilic substitution to afford thiols (Cu(SCN)2, then NaBH4) and sulfonic acids (pyridine SO3complex or chlorosulfonic acid). The R1agroup contained in Formula I can be derived either from the remaining ester or from Rf. Alternatively, the thiol and sulfonic acid derivatives can also be derived form the C-2 acids by manipulation of the carboxylic acid group as described previously.
[0361] In Scheme 4 is shown how to prepare pyrroles in which Q—E is attached to the 3-position. Cyclization of α-aminoketones as described previously with β-ketoesters can afford pyrroles. Hydrolysis under basic conditions can selectively hydrolyze the C-2 ester which upon heating should undergo decarboxylation to afford 2-unsubstituted pyrroles. The C-3 ester can then be hydrolyzed under acidic conditions to afford the 3-carboxypyrroles. Curtius rearrangement under conditions described previously can afford the 3-aminopyrroles. The carboxylic acids can be used to prepare the 3-mercapto and 3-sulfonic acid derivatives. The Hunsdiecker procedure can be used to prepare the 3-bromopyrroles. Halogen metal exchange with t-BuLi at low temperature followed by quenching with copper isocyanate should introduce an isocyanate group at C-3. This intermediate can be reduced with sodium borohydride to afford the 3-mercaptopyrroles. Alternatively, the carboxylic acids can be decarboxylated to afford pyrroles which can be N-protected with a bulky protecting group such as triisopropylsilyl (TIPS). This bulky group directs electrophilic substitution to C-3 of the pyrrole ring. Thus, reaction with copper isocyanate followed by sodium borohydride reduction and then fluoride induced TIPS deprotection can afford 3-mercaptopyrroles. Sulfonation of N-protected pyrrole with pyridine sulfur trioxide complex can again be directed to C-3 of the pyrrole to afford, after TIPS deprotection, the 3-sulfonic acids.
[0362] Another general method of pyrrole synthesis that can be used to prepare compounds of the present invention is shown in Scheme 5. This approach (Cushman et. al. J. Org. Chem.1996, 61, 4999) uses N-protected α-aminoketones and N-protected α-aminoaldehydes which are readily available from α-amino acids by initial preparation of the N-methoxy-N-methylamides followed by addition of an alkyl Grignard reagent (to produce ketones) or by reduction with a hydride reducing agent such as lithium aluminum hydride or diisobutylaluminum hydride. These aldehydes and ketones can be allowed to react with the enolates of additional ketones to afford intermediate aldol addition products which under acidic conditions cyclize to form pyrroles. The reacting partners in this approach can be of wide scope and can be chosen so that one skilled in the art will be able to prepare varied pyrroles.
[0363] Another very general method of pyrrole synthesis useful A for preparing compounds of the present invention is the Paal-Knorr reaction shown in Scheme 6. This reaction involves the reacting 1,4-diketones or 1,4-ketoaldehydes with primary amines to afford pyrroles. The starting 1,4-diketones and 1,4-ketoaldehydes can be prepared using standard enolate chemistry or by other procedures which are familiar to those skilled in the art of organic synthesis. The reaction is of wide scope and the starting materials can be chosen so that a variety of pyrroles can be prepared.
[0364] In Scheme 7 is shown how the compounds of Schemes 1-6 wherein Reis a carboxylic ester group can be converted into compounds containing the Z—A—B residue. For the amide linker (Formula I, Z=—CONH—), when Re=carboalkoxy, it can be hydrolyzed to the acid under either basic or acidic conditions depending on the substitution pattern, as described previously. Formation of the acid chloride with thionyl chloride followed by the addition of an appropriate amine H2N—A—B can afford the amide-linked compounds. Alternatively, the acid can be combined with amine H2N—A—B in the presence of a suitable peptide coupling agent, such as BOP-Cl, HBTU or DCC. In another method the ester can be directly coupled with an aluminum reagent, prepared by the addition of trimethylaluminum to the amine H2N—A—B.
[0365] To form ether- or thioether-linked compounds of Formula I (Z=—CH2O—, —CH2S—) the acid can be reduced to the alcohol. Preferred procedures for this transformation are reduction with borane THF complex, or a procedure involving the reduction of the mixed anhydride with sodium borohydride (IBCF═isobutyl chloroformate and NMM═N-methylmorpholine). Completion of the ether and thioether linked compounds of Formula I can readily be accomplished by the Mitsonobu protocol with an appropriate phenol, thiophenol or hydroxy- or mercaptoheterocycle HX—A—B (X═O, S) (Formula I, A=aryl or heteroaryl). Other ethers or thioethers (X═O,S) can be prepared following initial conversion of the alcohol to a suitable leaving group, such as tosylate. Where X═S, thioethers can be further oxidized to prepare the sulfones (Formula I, Z=—CH2SO2—).
[0366] To prepare the amine-linked compounds of Formula I (Z=—CH2NH—) the alcohol can be oxidized to the aldehyde by a number of procedures, two preferred methods of which are the Swern oxidation and oxidation with pyridinium chlorochromate (PCC). Alternatively, the aldehyde may be directly prepared by direct formylation of the pyrrole ring by the Vilsmeier-Haack procedure in certain cases, as described in previous schemes. Reductive amination of the aldehyde with an appropriate amine H2N—A—B and sodium cyanoborohydride can then afford the amine linked compounds.
[0367] The aldehyde also can be used to prepare the ketone-linked compounds of Formula I (Z=—COCH2—). Treatment with an organometallic species can afford the alcohol. The organometallic species (wherein M═magnesium or zinc) can preferably be prepared from the corresponding halide by treatment with metallic magnesium or zinc. These reagents should readily react with aldehydes to afford alcohols. Oxidation of the alcohol by any of a number of procedures, such as the Swern oxidation or PCC oxidation, can afford the ketones-linked compounds.
[0368] Additional compounds of Formula I in which the linking group m/z contains a nitrogen atom attached to ring M can be prepared by the procedures described in Scheme 8. The amines can be converted to sulfonamides (Formula I, m/z—NHSO2—) by treatment with an appropriate sulfonyl chloride B—A—SO2Cl in the presence of a base such as triethylamine. The amines can be converted into amides (Formula I, Z=—NHCO—) by treatment with an appropriate acid chloride Cl—CO—A—B in the presence of a base or by treatment with an appropriate carboxylic acid HO—CO—A—B in the presence of a suitable peptide coupling agent, such as DCC, HBTU or BOP. The amines can also be converted into amine-linked compounds (Formula I, Z=—NHCH2—) by reductive amination with an appropriate aldehyde OHC—A—B.
[0369] Additional compounds of Formula I in which the linking group Z contains a sulfur atom attached to ring M can be prepared by the procedures described in Scheme 9. Treatment of sulfonic acids with phosphorous pentachloride followed by treatment with an appropriate amine H2N—A—B can afford sulfonamide-linked compounds (Formula I, Z=—SO2NH—). The thiols can be alkylated with a suitable alkylating reagent in the presence of a base to afford thioethers (Formula I, Z=—SCH2—). These compounds can be further oxidized by a variety of reagents to afford the sulfone-linked compounds (Formula I, Z=—SO2CH2—).
[0370] Compounds of Formula I wherein ring M is an imidazole can be formed using procedures described in Schemes 10-16. N-Substituted imidazole derivatives can be made by the general procedure shown in Scheme 10, wherein V′ is either V or a precusor of (CH2)nV, V is nitro, amino, thio, hydroxy, sulfonic acid, sulfonic ester, sulfonyl chloride, ester, acid, or halide, n is 0 and 1, and PG is either a hydrogen or a protecting group. Substitution can be achieved by coupling an imidazole with a halogen containing fragment Q—E—G—Hal in the presence of a catalyst, such as base, Cu/CuBr/base, or Pd/base, followed by conversion of V′ to (CH2)nV. Then, Q can be converted to D, and finally V can be converted to —Z—A—B following the procedures outlined in Schemes 7-9. Alternatively, V can be converted to Z—A—B followed by deprotection of N. This product can then be coupled as before to obtain the desired imidazole.
[0371] One way to make amidino-phenyl-imidazole derivatives is shown in Scheme 11. 4-Imidazole carboxylic acid can be treated with thionyl chloride and then coupled with H2N—A—B in the presence of a base and then be heated with 3-fluorobenzonitrile in the presence of a base. The Pinner reaction using standard procedures known to those of skill in the art can be used to form the amidino group.
[0372] 1,2-Disubstituted and 1,5-disubstituted imidazole derivatives can be made by the general procedures described in Scheme 12, wherein R1bis either a hydrogen or an alkyl group and U is aldehyde, ester, acid, amide, amino, thiol, hydroxy, sulfonic acid, sulfonic ester, sulfonyl chloride, or methylene halide. Step a involves coupling in the presence of a catalyst, such as base, Cu/CuBr/base, or Pd/base. When R1bis a hydrogen, it can be deprotonated with a lithium base and trapped by formate, formamide, carbon dioxide, sulfonyl chloride (sulfur dioxide and then chlorine), or isocyanate to give 1,2-disubstituted imidazoles (Route b1). Also, in Route b1 when R1bis CH3, it can be oxidized with SeO2, MnO2, NaIO4/cat. RhCl3, or NBS to form U. When R1bis hydrogen, sequential deprotonation and quenching with a lithium base and trimethysilyl chloride, followed by a second deprotonation with a lithium base and quenching with formate, formamide, carbon dioxide, sulfonyl chloride (sulfur dioxide and then chlorine), or isocyanate can afford 1,5-disubstituted imidazoles (Route b2). When R1bis not hydrogen, the procedure of Route b2 can again be used to form 1,5-disubstituted imidazoles (Route b3).
[0373] A preferred way of making 1,2-disubstituted and 1,5-disubstituted imidazole derivatives is shown in Scheme 13. Imidazole can be heated with 3-fluorobenzonitrile in the presence of a base. The coupled product can then be treated with an alkyl lithium base and quenched with ClCO2Me to give the 1,2-disubstituted compound. Further treatment with a solution prepared of H2N—A—B in trimethylaluminum can give the amide, which can be further modified via the Pinner reaction to form the desired compound. The 1,5-disubstituted compounds can be made using the same procedure, except that the initial anion is protected and a second anion is formed which is then quenched as noted above. Further modifications can follow the same procedures as the 1,2-disubstituted compounds.
[0374] Another way of making 1,2-disubstituted imidazole derivatives is described in Scheme 14. By reacting an N-substituted imidazole with a cyanate, the amide can be obtained. This amide can then be coupled with group B as will be described later.
[0375] Another means of making 1,5-disubstituted imidazole derivatives is described in Scheme 15. Alkylation with 2-bromoethylacetate and subsequent reaction with Gold's reagent in the presence of a base, such as NaOMe, or LDA, can form ester substituted imidazoles which can be further modified as previously discribed.
[0376] A general procedure to make 2,4,5-trisubstituted or 4,5-disubstituted imidazole derivatives is shown in Scheme 16. After metal halogen exchange of the Q—E—G fragment, it can be reacted with the amide shown, brominated with NBS and cyclized with excess NH3and R1aCO2H to afford an imidazole. This can then be modified as before.
[0377] A general procedure to make 4,5-disubstituted triazole derivatives is described in Scheme 17. Ethyl propiolate can be substituted in the presence of CuI/Pd and then reacted with NaN3to form a triazole. The triazole can be converted as described previously.
[0378] The tetrazole compounds of the present invention where Z is —CONH— can be prepared as exemplified in Scheme 18. An appropiately substituted amine can be acylated with ethyl oxalyl chloride. The resulting amide can be converted to the tetrazole either by the methods described by Duncia (J. Org. Chem.1991, 2395-2400) or Thomas (Synthesis1993, 767-768). The amide can be converted to the iminoyl chloride first and the reacted with NaN3to form the 5-carboethoxytetrazole (J. Org. Chem.1993, 58, 32-35 and Bioorg. & Med. Chem. Lett.1996, 6, 1015-1020). The 5-carboethoxytetrazole can then be further modified as described in Scheme 7.
[0379] The tetrazole compounds of the present invention where Z is —CO— can also be prepared via iminoyl chloride (Chem. Ber.1961, 94, 1116 and J. Org. Chem.1976, 41, 1073) using an appropriately substituted acyl chloride as starting material. The ketone-linker can be reduced to compounds wherein Z is alkyl.
[0380] The methods described in Scheme 18 can also be used to synthesize compounds where the E—Q is linked to the carbon atom of the tetrazole as shown in Scheme 19. The 5-substituted tetrazole can then be alkylated or acylated to give the desired products.
[0381] The tetrazole compounds of the present invention wherein Z is —SO2NH—, —S—, —S(O)—, SO2— can be prepared from the thiol prepared as shown in Scheme 20. Appropiately substituted thioisocyanate can be reacted with sodium azide to give the 5-thiotetrazole (J. Org. Chem.1967, 32, 3580-3592). The thio-compound can be modified as described in Scheme 9.
[0382] The tetrazole compounds of the present invention wherein Z is —O— can be prepared via the same method described in Scheme 20 by using appropiately substituted isocyanate as the starting material. The hydroxy compound can be modified similarity to the thiols described in Scheme 9.
[0383] The tetrazole compounds of the present invention wherein Z is —NH—, —NHCO—, —NHSO2— can be prepared from 5-aminotetrazole, which can be prepared by Smiles Rearrangement as shown in Scheme 21. The thio-compound prepared as described in Scheme 20 can be alkylated with 2-chloroacetamide. The resulting compound can then be refluxed in ethanolic sodium hydroxide to give the corresponding 5-amino-tetrazole (Chem. Pharm. Bull.1991, 39, 3331-3334). The resulting 5-amino-tetrazole can then be alkylated or acylated to form the desired products.
[0384] Pyrazoles of Formula I (such as those described in Scheme can be prepared by the condensation of an appropriately substituted hydrazine with a variety of diketo esters. Condensations of this type typically afford a mixture of pyrazole regioisomers which can be effectively separated via silica gel column chromatography. The esters can be converted to Z—A—B as previously described.
[0385] Alternatively, if in Scheme 22, the starting diketone contains CH3in place of CO2Et, then the resulting methyl pyrazole can be separated and oxidized as in Route b1 in Scheme 12 to form the pyrazole carboxylic acid.
[0386] When ketoimidates are used for condensations with hydrazines the corresponding pyrazole amino esters are obtained (Scheme 23). Conversion of these intermediates to the final compounds of formula I can then be accomplished by the protection of the amino functionality with a suitable protecting group or by derivatization (e.g. sulfonamide) and then modifying the ester as previously noted.
[0387] As shown in Scheme 24, pyrazoles wherein the 4-position is substituted can be prepared by bromination (bromine or NBS in either dichloromethane or acetic acid) of the initial pyrazole. Conversion of 4-bromo-pyrazole to 4-carboxylic acid pyrazole can be accomplished by a number of methods commonly known to those in the art of organic synthesis. Further manipulations as previously described can afford pyrazoles of the present invention.
[0388] Pyrazoles can also be prepared according to method described in Scheme 25. The bromo-pyrazoles are formed as in Scheme 24. QE can then be coupled using palladium catalysed Suzuki cross-coupling methodology. Further modification is achieved as previously described.
[0389] 5-substituted phenylpyrazoles can be prepared by the method shown in Scheme 26. Conversion of the 5-hydroxy pyrazole to its triflate (triflic anhydride, lutidine in dichloromethane) or bromide (POBr3) followed by palladium Suzuki cross-coupling with an apppropriately substituted phenylboronic acid should then afford 5-substituted pyrazoles. Conversion of this intermediate to the 4-bromo derivative followed by its carbonylation as described in Scheme 24 should then afford the appropriate ester which can be further afford the compounds of formula I.
[0390] 1-Substituted-1,2,3-triazoles of the present invention can be prepared by the treatment of an appropriately substituted azide with a variety of dipolarophiles (Tetrahedron1971, 27, 845 and J. Amer. Chem. Soc.1951, 73, 1207) as shown in Scheme 27. Typically a mixture of regioisomers are obtained which can be easily separated and elaborated to the triazole carboxylic acids. Further transformations as previously described can then afford the compounds of the present invention.
[0391] 1,2,4-Triazoles of the present invention can be obtained by the methodology of Huisgen et al (Liebigs Ann. Chem.1962, 653, 105) by the cycloaddition of nitriliminium species (derived from the treatment of triethylamine and chloro hydrazone) and an appropriate nitrile dipolarophile (Scheme 28). This methodology provides a wide variety of 1,2,4 triazoles with a varied substitution pattern at the 1, 3, and 5 positions.
[0392] 1,2,4 Triazoles can also be prepared by the methodology of Zecchi et al (Synthesis1986, 9, 772) by an aza Wittig condensation (Scheme 29).
[0393] 1,2,4-Triazoles wherein the —E—D(Q) substituent is at the 5-position of the triazole can be obtained as shown in Scheme 30.
[0394] 1,3,4-Triazoles of the present invention can be obtained via the methodology of Moderhack et al (J. Prakt. Chem.1996, 338, 169). As shown in Scheme 31, this reaction involves the condensation of a carbazide with an appropriately substituted commercially available thioisocyanate to form the cyclic thiourea derivative. Alkylation or nucleophilic displacement reactions on the thiono-urea intermediate can then afford a thio-alkyl or aryl intermediate which can be hydrolysed, oxidized and decarboxylated to the 5-H 2-thio-triazole intermediate which can be converted to the compounds of the present invention. Alternatively the thiono-urea intermediate can be oxidized directly to the 2-H triazole which can then be converted to the ester and modified as previously described. The thiono-urea intermediate can also be oxidized to the sulfonyl chloride by methods shown previously.
[0395] The imidazole core shown in Scheme 32 can be prepared by the condensation of 3-cyanoaniline with n-butylglyoxylate to afford the imine which can then be treated with TosylMIC in basic methanol to afford the desired imidazole compound. Coupling of the ester under standard conitions then affords a variety of analogs which then can be further manipulated to afford e.g. the benzylamine or the benzamidines.
[0396] Compounds of the present invention wherein AB is a biphenylamine or similar amine may be prepared as shown in Scheme 33. 4-Bromoaniline can be protected as Boc-derivative and coupled to a phenylboronic acid under Suzuki conditions (Bioorg. Med. Chem. Lett.1994, 189). Deprotection with TFA provides the aminobiphenyl compound. Other similar amines wherein A and/or B are heterocycles can be prepared by the same method using appropiately substituted boronic acids and arylbromide. The bromoaniline can also be linked to the core ring structures first as described above, and then undergo a Suzuki reaction to give the desired product.
[0397] Compounds of the present invention wherein A—B is A—X—Y can be prepared like the piperazine derivative shown in Scheme 34.
[0398] Scheme 35 shows how one can couple cyclic groups wherein X═NH, O, or S.
[0399] When B is defined as X—Y, the following description applies. Groups A and B are available either through commercial sources, known in the literature or readily synthesized by the adaptation of standard procedures known to practioners skilled in the art of organic synthesis. The required reactive functional groups appended to analogs of A and B are also available either through commercial sources, known in the literature or readily synthesized by the adaptation of standard procedures known to practioners skilled in the art of organic synthesis. In the tables that follow the chemistry required to effect the coupling of A to B is outlined.
[0400] The chemistry of Table A can be carried out in aprotic solvents such as a chlorocarbon, pyridine, benzene or toluene, at temperatures ranging from −20° C. to the reflux point of the solvent and with or without a trialkylamine base.
[0401] The coupling chemistry of Table B can be carried out by a variety of methods. The Grignard reagent required for Y is prepared from a halogen analog of Y in dry ether, dimethoxyethane or tetrahydrofuran at 0° C. to the reflux point of the solvent. This Grignard reagent can be reacted directly under very controlled conditions, that is low temeprature (−20° C. or lower) and with a large excess of acid chloride or with catalytic or stoichiometric copper bromide.dimethyl sulfide complex in dimethyl sulfide as a solvent or with a variant thereof. Other methods available include transforming the Grignard reagent to the cadmium reagent and coupling according to the procedure of Carson and Prout (Org. Syn. Col. Vol. 3 (1955) 601) or a coupling mediated by Fe(acac)3according to Fiandanese et al.(Tetrahedron Lett., (1984) 4805), or a coupling mediated by manganese (II) catalysis (Cahiez and Laboue, Tetrahedron Lett., 33(31), (1992) 4437).
[0402] The ether and thioether linkages of Table C can be prepared by reacting the two components in a polar aprotic solvent such as acetone, dimethylformamide or dimethylsulfoxide in the presence of a base such as potassium carbonate, sodium hydride or potassium t-butoxide at temperature ranging from ambient temperature to the reflux point of the solvent used.
[0403] The thioethers of Table C serve as a convenient starting material for the preparation of the sulfoxide and sulfone analogs of Table D. A combination of wet alumina and oxone can provide a reliable reagent for the oxidation of the thioether to the sulfoxide while m-chloroperbenzoic acid oxidation will give the sulfone.
[0404] In Table E several methods of transforming a functional group Q into group D of Formula 1 are shown. While not all possible functional groups for Q and D are listed and the synthetic methods suggested are not comprehensive, Table E is meant to illustrate strategies and transformations available to a practitioner skilled in the art of organic synthesis for preparing compounds of Formula 1. In reaction 1 of Table E the transformation of a nitrile into an amidine by the Pinner methodology is shown; in reaction 2 the direct reduction of a nitrile by a hydride reducing agent to a methylene amine is illustrated. In reaction 3, the utility of a carboxylic acid, which may be readily derived from its ester or a nitrile if necessary, in the preparation of a methylene amine is shown. This synthetic route is exceptionally flexible because of the several stable intermediates prepared en route to the final product. As outlined, formation of an activated analog, such as the mixed anhydride, allows for the mild reduction of the acid to the methylene alcohol, this may in turn be transformed into a leaving group by sulfonylation or halogenation or protected with a suitable protecting group to be transformed later in the synthesis as the chemistry demands. Once the methylene alcohol is so activated, displacement by an efficient nitrogen nucleophile, such as azide anion, can again provide another suitably stable analog, -the methylene azide- which may be used as a protected form of the methylene amine or transformed directly into the methylene amine group by reduction. Reaction 4 addresses the problem of appending the amine functionality directly through a bond to group E of Formula 1. Once again, the carboxylic acid provides a convenient entre into this selection for group D. The well-know Curtius rearrangement is illustrated here; an activated acid analog can be used to form an acyl azide which upon thermal decomposition is rearranged to the corresponding isocyanate. The isocyanate intermediate may then be captured as a stable carbamate by the addition of a suitable alcohol and further heating. This carbamate can be used as a stable protecting group for the amine or cleaved directly to the desired D. Alternatively, it may be convenient to quench the isocyanate intermediate with water to give the amine directly.

Utility
[0535] The compounds of this invention are useful as anticoagulants for the treatment or prevention of thromboembolic disorders in mammals. The term “thromboembolic disorders” as used herein includes arterial or venous cardiovascular or cerebrovascular thromboembolic disorders, including, for example, unstable angina, first or recurrent myocardial infarction, ischemic sudden death, transient ischemic attack, stroke, atherosclerosis, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary and cerebral arterial thrombosis, cerebral embolism, kidney embolisms, and pulmonary embolisms. The anticoagulant effect of compounds of the present invention is believed to be due to inhibition of factor Xa or thrombin.
[0536] The effectiveness of compounds of the present invention as inhibitors of factor Xa was determined using purified human factor Xa and synthetic substrate. The rate of factor Xa hydrolysis of chromogenic substrate S2222 (Kabi Pharmacia, Franklin, OH) was measured both in the absence and presence of compounds of the present invention. Hydrolysis of the substrate resulted in the release of pNA, which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nM. A decrease in the rate of absorbance change at 405 nm in the presence of inhibitor is indicative of enzyme inhibition. The results of this assay are expressed as inhibitory constant, Ki.
[0537] Factor Xa determinations were made in 0.10 M sodium phosphate buffer, pH 7.5, containing 0.20 M NaCl, and 0.5% PEG 8000. The Michaelis constant, Km, for substrate hydrolysis was determined at 25° C. using the method of Lineweaver and Burk. Values of Kiwere determined by allowing 0.2-0.5 nM human factor Xa (Enzyme Research Laboratories, South Bend, Ind.) to react with the substrate (0.20 mM-1 mM) in the presence of inhibitor. Reactions were allowed to go for 30 minutes and the velocities (rate of absorbance change vs time) were measured in the time frame of 25-30 minutes. The following relationship was used to calculate Kivalues:
[0538] (vo-vs)/vs=I/(Ki(1+S/Km))
[0539] where:
[0540] vois the velocity of the control in the absence of inhibitor;
[0541] vsis the velocity in the presence of inhibitor;
[0542] I is the concentration of inhibitor;
[0543] Kiis the dissociation constant of the enzyme:inhibitor complex;
[0544] S is the concentration of substrate;
[0545] Kmis the Michaelis constant.
[0546] Using the methodology described above, a number of compounds of the present invention were found to exhibit a Kiof ≦10 μm, thereby confirming the utility of the compounds of the present invention as effective Xa inhibitors.
[0547] The antithrombotic effect of compounds of the present invention can be demonstrated in a rabbit arterio-venous (AV) shunt thrombosis model. In this model, rabbits weighing 2-3 kg anesthetized with a mixture of xylazine (10 mg/kg i.m.) and ketamine (50 mg/kg i.m.) are used. A saline-filled AV shunt device is connected between the femoral arterial and the femoral venous cannulae. The AV shunt device consists of a piece of 6-cm tygon tubing which contains a piece of silk thread. Blood will flow from the femoral artery via the AV-shunt into the femoral vein. The exposure of flowing blood to a silk thread will induce the formation of a significant thrombus. After forty minutes, the shunt is disconnected and the silk thread covered with thrombus is weighed. Test agents or vehicle will be given (i.v., i.p., s.c., or orally) prior to the opening of the AV shunt. The percentage inhibition of thrombus formation is determined for each treatment group. The ID50 values (dose which produces 50% inhibition of thrombus formation) are estimated by linear regression.
[0548] The compounds of formula (I) may also be useful as inhibitors of serine proteases, notably human thrombin, plasma kallikrein and plasmin. Because of their inhibitory action, these compounds are indicated for use in the prevention or treatment of physiological reactions, blood coagulation and inflammation, catalyzed by the aforesaid class of enzymes. Specifically, the compounds have utility as drugs for the treatment of diseases arising from elevated thrombin activity such as myocardial infarction, and as reagents used as anticoagulants in the processing of blood to plasma for diagnostic and other commercial purposes.
[0549] Some compounds of the present invention were shown to be direct acting inhibitors of the serine protease thrombin by their ability to inhibit the cleavage of small molecule substrates by thrombin in a purified system. In vitro inhibition constants were determined by the method described by Kettner et al. in J. Biol. Chem.265, 18289-18297 (1990), herein incorporated by reference. In these assays, thrombin-mediated hydrolysis of the chromogenic substrate S2238 (Helena Laboratories, Beaumont, Tex.) was monitored spectrophotometrically. Addition of an inhibitor to the assay mixture results in decreased absorbance and is indicative of thrombin inhibition. Human thrombin (Enzyme Research Laboratories, Inc., South Bend, Ind.) at a concentration of 0.2 nM in 0.10 M sodium phosphate buffer, pH 7.5, 0.20 M NaCl, and 0.5% PEG 6000, was incubated with various substrate concentrations ranging from 0.20 to 0.02 mM. After 25 to 30 minutes of incubation, thrombin activity was assayed by monitoring the rate of increase in absorbance at 405 nm which arises owing to substrate hydrolysis. Inhibition constants were derived from reciprocal plots of the reaction velocity as a function of substrate concentration using the standard method of Lineweaver and Burk. Using the methodology described above, some compounds of this invention were evaluated and found to exhibit a Kiof less than 10 μm, thereby confirming the utility of the compounds of the present invention as effective thrombin inhibitors.
[0550] The compounds of the present invention can be administered alone or in combination with one or more additional therapeutic agents. These include other anti-coagulant or coagulation inhibitory agents, anti-platelet or platelet inhibitory agents, thrombin inhibitors, or thrombolytic or fibrinolytic agents.
[0551] The compounds are administered to a mammal in a therapeutically effective amount. By “therapeutically effective amount” it is meant an amount of a compound of Formula I that, when administered alone or in combination with an additional therapeutic agent to a mammal, is effective to prevent or ameliorate the thromboembolic disease condition or the progression of the disease.
[0552] By “administered in combination” or “combination therapy” it is meant that the compound of Formula I and one or more additional therapeutic agents are administered concurrently to the mammal being treated. When administered in combination each component may be administered at the same time or sequentially in any order at different points in time. Thus, each component may be administered separately but sufficiently closely in time so as to provide the desired therapeutic effect. Other anticoagulant agents (or coagulation inhibitory agents) that may be used in combination with the compounds of this invention include warfarin and heparin, as well as other factor Xa inhibitors such as those described in the publications identified above under Background of the Invention.
[0553] The term anti-platelet agents (or platelet inhibitory agents), as used herein, denotes agents that inhibit platelet function such as by inhibiting the aggregation, adhesion or granular secretion of platelets. Such agents include, but are not limited to, the various known non-steroidal anti-inflammatory drugs (NSAIDS) such as aspirin, ibuprofen, naproxen, sulindac, indomethacin, mefenamate, droxicam, diclofenac, sulfinpyrazone, and piroxicam, including pharmaceutically acceptable salts or prodrugs thereof. Of the NSAIDS, aspirin (acetylsalicyclic acid or ASA), and piroxicam are preferred. Other suitable anti-platelet agents include ticlopidine, including pharmaceutically acceptable salts or prodrugs thereof. Ticlopidine is also a preferred compound since it is known to be gentle on the gastro-intestinal tract in use. Still other suitable platelet inhibitory agents include IIb/IIIa antagonists, thromboxane-A2-receptor antagonists and thromboxane-A2-synthetase inhibitors, as well as pharmaceutically acceptable salts or prodrugs thereof.
[0554] The term thrombin inhibitors (or anti-thrombin agents), as used herein, denotes inhibitors of the serine protease thrombin. By inhibiting thrombin, various thrombin-mediated processes, such as thrombin-mediated platelet activation (that is, for example, the aggregation of platelets, and/or the granular secretion of plasminogen activator inhibitor-1 and/or serotonin) and/or fibrin formation are disrupted. A number of thrombin inhibitors are known to one of skill in the art and these inhibitors are contemplated to be used in combination with the present compounds. Such inhibitors include, but are not limited to, boroarginine derivatives, boropeptides, heparins, hirudin and argatroban, including pharmaceutically acceptable salts and prodrugs thereof. Boroarginine derivatives and boropeptides include N-acetyl and peptide derivatives of boronic acid, such as C-terminal a-aminoboronic acid derivatives of lysine, ornithine, arginine, homoarginine and corresponding isothiouronium analogs thereof. The term hirudin, as used herein, includes suitable derivatives or analogs of hirudin, referred to herein as hirulogs, such as disulfatohirudin. Boropeptide thrombin inhibitors include compounds described in Kettner et al, U.S. Pat. No. 5,187,157 and European Patent Application Publication Number 293 881 A2, the disclosures of which are hereby incorporated herein by reference. Other suitable boroarginine derivatives and boropeptide thrombin inhibitors include those disclosed in PCT Application Publication Number 92/07869 and European Patent Application Publication Number 471,651 A2, the disclosures of which are hereby incorporated herein by reference.
[0555] The term thrombolytics (or fibrinolytic) agents (or thrombolytics or fibrinolytics), as used herein, denotes agents that lyse blood clots (thrombi). Such agents include tissue plasminogen activator, anistreplase, urokinase or streptokinase, including pharmaceutically acceptable salts or prodrugs thereof. The term anistreplase, as used herein, refers to anisoylated plasminogen streptokinase activator complex, as described, for example, in European Patent Application No. 028,489, the disclosure of which is hereby incorporated herein by reference herein. The term urokinase, as used herein, is intended to denote both dual and single chain urokinase, the latter also being referred to herein as prourokinase.
[0556] Administration of the compounds of Formula I of the invention in combination with such additional therapeutic agent, may afford an efficacy advantage over the compounds and agents alone, and may do so while permitting the use of lower doses of each. A lower dosage minimizes the potential of side effects, thereby providing an increased margin of safety.
[0557] The compounds of the present invention are also useful as standard or reference compounds, for example as a quality standard or control, in tests or assays involving the inhibition of factor Xa. Such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving factor Xa. For example, a compound of the present invention could be used as a reference in an assay to compare its known activity to a compound with an unknown activity. This would ensure the experimenter that the assay was being performed properly and provide a basis for comparison, especially if the test compound was a derivative of the reference compound. When developing new assays or protocols, compounds according to the present invention could be used to test their effectiveness.
[0558] The compounds of the present invention may also be used in diagnostic assays involving factor Xa. For example, the presence of factor Xa in an unknown sample could be determined by addition of chromogenic substrate S2222 to a series of solutions containing test sample and optionally one of the compounds of the present invention. If production of pNA is observed in the solutions containing test sample, but not in the presence of a compound of the present invention, then one would conclude factor Xa was present.
Dosage and Formulation
[0559] The compounds of this invention can be administered in such oral dosage forms as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions. They may also be administered in intravenous (bolus or infusion), intraperitoneal, subcutaneous, or intramuscular form, all using dosage forms well known to those of ordinary skill in the pharmaceutical arts. They can be administered alone, but generally will be administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.
[0560] The dosage regimen for the compounds of the present invention will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient,and the effect desired. A physician or veterinarian can determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the thromboembolic disorder.
[0561] By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.001 to 1000 mg/kg of body weight, preferably between about 0.01 to 100 mg/kg of body weight per day, and most preferably between about 1.0 to 20 mg/kg/day. Intravenously, the most preferred doses will range from about 1 to about 10 mg/kg/minute during a constant rate infusion. Compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.
[0562] Compounds of this invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using transdermal skin patches. When administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.
[0563] The compounds are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as pharmaceutical carriers) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, elixirs, syrups and the like, and consistent with conventional pharmaceutical practices.
[0564] For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic, pharmaceutically acceptable, inert carrier such as lactose, starch, sucrose, glucose, methyl callulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like; for oral administration in liquid form, the oral drug components can be combined with any oral, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like.
[0565] The compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines.
[0566] Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxide-polylysine substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacylates, and crosslinked or amphipathic block copolymers of hydrogels.
[0567] Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 100 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition.
[0568] Gelatin capsules may contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract.
[0569] Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.
[0570] In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.
[0571] Suitable pharmaceutical carriers are described in Reminaton's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.
[0572] Representative useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows:
Capsules
[0573] A large number of unit capsules can be prepared by filling standard two-piece hard gelatin capsules each with 100 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate.
Soft Gelatin Capsules
[0574] A mixture of active ingredient in a digestable oil such as soybean oil, cottonseed oil or olive oil may be prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 milligrams of the active ingredient. The capsules should be washed and dried.
Tablets
[0575] Tablets may be prepared by conventional procedures so that the dosage unit is 100 milligrams of active ingredient, 0.2 milligrams of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 milligrams of microcrystalline cellulose, 11 milligrams of starch and 98.8 milligrams of lactose. Appropriate coatings may be applied to increase palatability or delay absorption.
Injectable
[0576] A parenteral composition suitable for administration by injection may be prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol and water. The solution should be made isotonic with sodium chloride and sterilized.
Suspension
[0577] An aqueous suspension can be prepared for oral administration so that each 5 mL contain 100 mg of finely divided active ingredient, 200 mg of sodium carboxymethyl cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol solution, U.S.P., and 0.025 mL of vanillin.
[0578] Where the compounds of this invention are combined with other anticoagulant agents, for example, a daily dosage may be about 0.1 to 100 milligrams of the compound of Formula I and about 1 to 7.5 milligrams of the second anticoagulant, per kilogram of patient body weight. For a tablet dosage form, the compounds of this invention generally may be present in an amount of about 5 to 10 milligrams per dosage unit, and the second anti-coagulant in an amount of about 1 to 5 milligrams per dosage unit.
[0579] Where the compounds of Formula I are administered in combination with an anti-platelet agent, by way of general guidance, typically a daily dosage may be about 0.01 to 25 milligrams of the compound of Formula I and about 50 to 150 milligrams of the anti-platelet agent, preferably about 0.1 to 1 milligrams of the compound of Formula I and about 1 to 3 milligrams of antiplatelet agents, per kilogram of patient body weight.
[0580] Where the compounds of Formula I are adminstered in combination with thrombolytic agent, typically a daily dosage may be about 0.1 to 1 milligrams of the compound of Formula I, per kilogram of patient body weight and, in the case of the thrombolytic agents, the usual dosage of the thrombolyic agent when administered alone may be reduced by about 70-80% when administered with a compound of Formula I.
[0581] Where two or more of the foregoing second therapeutic agents are administered with the compound of Formula I, generally the amount of each component in a typical daily dosage and typical dosage form may be reduced relative to the usual dosage of the agent when administered alone, in view of the additive or synergistic effect of the therapeutic agents when administered in combination.
[0582] Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of Formula I and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material which effects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a lowviscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component.
[0583] These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure.
[0584] Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise that as specifically described herein.
