FIELD OF THE INVENTION
This application claims priority under 35 U.S.C. 119 (e) from provisional application Ser. No. 60/009,088, filed Dec. 22, 1995 and 60/025,699 filed Aug. 9, 1996.
This invention relates to novel heterocycles which are useful as antagonists of the .alpha..sub.v .beta..sub.3 integrin and related cell surface adhesive protein receptors, to pharmaceutical compositions containing such compounds, processes for preparing such compounds, and to methods of using these compounds, alone or in combination with other therapeutic agents, for the inhibition of cell adhesion, the treatment of angiogenic disorders, inflammation, bone degradation, cancer metastasis, diabetic retinopathy, thrombosis, restenosis, macular degeneration, and other conditions mediated by cell adhesion and/or cell migration and/or angiogenesis.
BACKGROUND OF THE INVENTION
Angiogenesis or neovascularization is critical for normal physiological processes such as embryonic development and wound repair (Folkman and Shing, J. Biol. Chem. 1992, 26:10931-10934; D'Amore and Thompson, Ann. Rev. Physiol. 1987, 49:453-464). However, angiogenesis also occurs pathologically, for example, in ocular neovascularization (leading to diabetic retinopathy, neovascular glaucoma, retinal vein occlusion and blindness), in rheumatoid arthritis and in solid tumors (Folkman and Shing, J. Biol. Chem., 1992, 267:10931-10934; Blood and Zetter, Biochim. Biophys. Acta., 1990, 1032:118-128).
Tumor dissemination, or metastasis, involves several distinct and complementary components, including the penetration and traversing of tumor cells through basement membranes and the establishment of self-sustaining tumor foci in diverse organ systems. To this end, angiogenesis is critical to tumor survival. Without neovascularization, tumor cells lack the nourishment to divide and will not be able to leave the primary tumor site (Folkman and Shing, J. Biol. Chem., 1992, 267:10931-10934).
Inhibition of angiogenesis in animal models of cancer has been shown to result in tumor growth suppression and prevention of metastatic growth (Herblin et al., Exp. Opin. Ther. Patents, 1994, 1-14). Many angiogenic inhibitors have been directed toward blocking initial cytokine-dependent induction of new vessel growth, e.g. antibodies to endothelial cell growth factors. However, these approaches are problematic because tumor and inflammatory cells can secrete multiple activators of angiogenesis (Brooks et al., Cell, 1994, 79:1157-1164). Therefore, a more general approach that would allow inhibition of angiogenesis due to a variety of stimuli would be of benefit.
The integrin .alpha..sub.v .beta..sub.3, sometimes called the vitronectin receptor, is preferentially expressed on angiogenic blood vessels in chick and man (Brooks et al., Science, 1994, 264:569-571; Enenstein and Kramer, J. Invest. Dermatol., 1994, 103:381-386). .alpha..sub.v .beta..sub.3 is the most promiscuous member of the integrin family, allowing endothelial cells to interact with a wide variety of extracellular matrix components (Hynes, Cell, 1992, 69:11-25). These adhesive interactions are considered to be critical for angiogenesis since vascular cells must ultimately be capable of invading virtually all tissues.
While integrin .alpha..sub.v .beta..sub.3 promotes adhesive events important for angiogenesis, this receptor also transmits signals from the extracellular environment to the intracellular compartment (Leavesley et al., J. Cell Biol., 1993, 121:163-170, 1993). For example, the interaction between the .alpha..sub.v .beta..sub.3 integrin and extracellular matrix components promotes a calcium signal required for cell motility.
During endothelium injury, the basement membrane zones of blood vessels express several adhesive proteins, including but not limited to von Willebrand factor, fibronectin, and fibrin. Additionally, several members of the integrin family of adhesion receptors are expressed on the surface of endothelial, smooth muscle and on other circulating cells. Among these integrins is .alpha..sub.v .beta..sub.3, the endothelial cell, fibroblast, and smooth muscle cell receptor for adhesive proteins including von Willebrand factor, fibrinogen (fibrin), vitronectin, thrombospondin, and osteopontin. These integrins initiate a calcium-dependent signaling pathway that can lead to endothelial cell and smooth muscle cell migration and, therefore, may play a fundamental role in vascular cell biology.
Recently, an antibody to the .alpha..sub.v .beta..sub.3 integrin has been developed that inhibits the interaction of this integrin with agonists such as vitronectin (Brooks et al., Science, 1994, 264:569-571). Application of this antibody has been shown to disrupt ongoing angiogenesis on the chick chorioallantoic membrane (CAM), leading to rapid regression of histologically distinct human tumor transplanted onto the CAM (Brooks et al., Cell, 1994, 79:1157-1164). In this model, antagonists of the .alpha..sub.v .beta..sub.3 integrin induced apoptosis of the proliferating angiogenic vascular cells, leaving pre-existing quiescent blood vessels unaffected. Thus, .alpha..sub.v .beta..sub.3 integrin antagonists have been shown to inhibit angiogenesis and are recognized as being useful as therapeutic agents for the treatment of human diseases such as cancer, restenosis, thromoembolic disorders, rheumatoid arthritis and ocular vasculopathies (Folkman and Shing, J. Biol. Chem., 1992, 267:10931-10934).
Increasing numbers of other cell surface receptors have been identified which bind to extracellular matrix ligands or other cell adhesion ligands thereby mediating cell-cell and cell-matrix adhesion processes. Like the .alpha..sub.v .beta..sub.3 integrin, these receptors belong to the integrin gene superfamily and are composed of heterodimeric transmembrane glycoproteins containing .alpha.- and .beta.-subunits. Integrin subfamilies contain a common .beta.-subunit combined with different .alpha.-subunits to form adhesion receptors with unique specificity. The genes for eight distinct .beta.-subunits have been cloned and sequenced to date.
The integrin .alpha..sub.v .beta..sub.3 is a member of the .beta..sub.3 integrin subfamily and has been described on platelets, endothelial cells, melanoma, smooth muscle cells, and osteoclasts (Horton and Davies, J. Bone Min. Res. 1989, 4:803-808; Davies et al., J. Cell. Biol. 1989, 109:1817-1826; Horton, Int. J. Exp. Pathol., 1990, 71:741-759). Like the major platelet integrin GPIIb/IIIa, the vitronectin receptor binds a variety of RGD-containing adhesive proteins such as vitronectin, fibronectin, von Willibrand factor, fibrinogen, osteopontin, bone sialoprotein II and thrombospondin in a manner mediated by the RGD sequence.
A key event in bone resorption is the adhesion of osteoclasts to the matrix of bone. Studies with monoclonal antibodies have implicated the .alpha..sub.v .beta..sub.3 receptor in this process and suggest that a selective .alpha..sub.v .beta..sub.3 antagonist would have utility in blocking bone resorption in diseases such as osteoporosis (Horton et al., J. Bone Miner. Res., 1993, 8:239-247; Helfrich et al., J. Bone Miner. Res., 1992, 7:335-343).

In the present invention it has been discovered that the compounds of Formula Ia, Ib or Ic above are useful as inhibitors of cell-matrix and cell-cell adhesion processes. The present invention includes novel compounds of Formula Ia, Ib or Ic and methods for using such compounds for the prevention or treatment of diseases resulting from abnormal cell adhesion to the extracellular matrix which comprises administering to a host in need of such treatment a therapeutically effective amount of such compound of Formula Ia, Ib or Ic.
In the present invention it has also been discovered that the compounds of Formula Ia, Ib or Ic above are useful as inhibitors of .alpha..sub.v .beta..sub.3. The compounds of the present invention inhibit the binding of vitronectin to .alpha..sub.v .beta..sub.3 and inhibit cell adhesion.
The present invention also provides pharmaceutical compositions comprising a compound of Formula Ia, Ib or Ic and a pharmaceutically acceptable carrier.
The compounds of Formula Ia, Ib or Ic of the present invention are useful for the treatment (including prevention) of angiogenic disorders, comprising administering to a mammal in need of such treatment a therapeutically effective amount of a compound of Formula Ia, Ib or Ic described above. The term "angiogenic disorders" as used herein includes conditions involving abnormal neovascularization, such as tumor metastasis and ocular neovascularization, including, for example, diabetic retinopathy, neovascular glaucoma, age-related macular degeneration, and retinal vein occlusion.
The compounds of Formula Ia, Ib or Ic of the present invention are also useful for the treatment (including prevention) of thromboembolic disorders, comprising administering to a mammal in need of such treatment a therapeutically effective amount of a compound of Formula Ia, Ib or Ic described above. The term "thromboembolic disorders" as used herein includes conditions involving platelet activation and aggregation, such as arterial or venous cardiovascular or cerebrovascular thromboembolic disorders, including, for example, thrombosis, 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, myocardial infarction, cerebral embolisms, kidney embolisms, pulmonary embolisms, or such disorders associated with diabetes.
The compounds of Formula Ia, Ib or Ic of the present invention may also be useful for the treatment or prevention of other diseases which involve cell adhesion processes, including, but not limited to, inflammation, bone degradation, restenosis, rheumatoid arthritis, asthma, allergies, adult respiratory distress syndrome, graft versus host disease, organ transplantation rejection, septic shock, psoriasis, eczema, contact dermatitis, osteoporosis, osteoarthritis, atherosclerosis, inflammatory bowel disease and other autoimmune diseases. The compounds of Formula Ia, Ib or Ic of the present invention may also be useful for wound healing.
The compounds of the present invention may be used for other ex vivo applications to prevent cellular adhesion in biological samples.
The compounds of the present invention can also be administered in combination with one or more additional therapeutic agents selected from: anti-coagulant or coagulation inhibitory agents, such as heparin or warfarin; anti-platelet or platelet inhibitory agents, such as aspirin, piroxicam, or ticlopidine; thrombin inhibitors such as boropeptides, hirudin or argatroban; or thrombolytic or fibrinolytic agents, such as plasminogen activators, anistreplase, urokinase, or streptokinase.
The compounds of Formula Ia, Ib or Ic of the present invention can be administered in combination with one or more of the foregoing additional therapeutic agents, thereby to reduce the doses of each drug required to achieve the desired therapeutic effect. Thus, the combination treatment of the present invention permits the use of lower doses of each component, with reduced adverse, toxic effects of each component. A lower dosage minimizes the potential of side effects of the compounds, thereby providing an increased margin of safety relative to the margin of safety for each component when used as a single agent. Such combination therapies may be employed to achieve synergistic or additive therapeutic effects for the treatment of thromboembolic or other disorders.
By "therapeutically effective amount" is meant an amount of a compound of Formula Ia, Ib or Ic that when administered alone or in combination with an additional therapeutic agent to a cell or mammal is effective to prevent or ameliorate the disease condition or the progression of the disease.
By "administered in combination" or "combination therapy" it is meant that the compound of Formula Ia, Ib or Ic 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.
The term anti-coagulant agents (or coagulation inhibitory agents), as used herein, denotes agents that inhibit blood coagulation. Such agents include warfarin sodium crystalline clathrate and heparin.
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 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. 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 gastrointestinal tract in use.

The compounds herein described may have asymmetric centers. Unless otherwise indicated, all chiral, diastereomeric and racemic forms are included in the present invention. Many geometric isomers of olefins, C.dbd.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. It will be appreciated that compounds of the present invention that contain asymmetrically substituted carbon atoms 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. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomer form is specifically indicated.
When any variable (for example but not limited to, R.sup.2, R.sup.4, R.sup.6, R.sup.7, R.sup.8, R.sup.12,and R.sup.14, n, etc.) occurs more than one time in any constituent or in any formula, its definition on each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-3 R.sup.4, then said group may optionally be substituted with up to three R.sup.4 and R.sup.4 at each occurrence is selected independently from the defined list of possible R.sup.4. Also, by way of example, for the group --N(R.sup.5a).sub.2, each of the two R.sup.5a substituents on N is independently selected from the defined list of possible R.sup.5a. Similarly, by way of example, for the group --C(R.sup.7).sub.2 --, each of the two R.sup.7 substituents on C is independently selected from the defined list of possible R.sup.7.
When a bond to a substituent is shown to cross the bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a bond joining a substituent to another group is not specifically shown or the atom in such other group to which the bond joins is not specifically shown, then such substituent may form a bond with any atom on such other group.
When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of Formula Ia, Ib or Ic, then such substituent may be bonded via any atom in such substituent. For example, when the substituent is piperazinyl, piperidinyl, or tetrazolyl, unless specified otherwise, said piperazinyl, piperidinyl, tetrazolyl group may be bonded to the rest of the compound of Formula Ia, Ib or Ic via any atom in such piperazinyl, piperidinyl, tetrazolyl group.
Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. By stable compound or stable structure it is meant herein a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.
The term "substituted", as used herein, means that any one or more hydrogen 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., .dbd.O), then 2 hydrogens on the atom are replaced.

Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like.
"Prodrugs" are considered to be any covalently bonded carriers which release the active parent drug according to Formula Ia, Ib or Ic in vivo when such prodrug is administered to a mammalian subject. Prodrugs of the compounds of Formula Ia, Ib or Ic are prepared by modifying functional groups present in the compounds in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compounds. Prodrugs include compounds of Formula Ia, Ib or Ic wherein hydroxyl, amino, sulfhydryl, or carboxyl groups are bonded to any group that, when administered to a mammalian subject, cleaves to form a free hydroxyl, amino, sulfhydryl, or carboxyl 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 Ia, Ib or Ic, and the like.

Synthesis
The compounds of the present invention can be prepared in a number of ways well 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 variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. All references cited herein are hereby incorporated in their entirety herein by reference.
Compounds of Formula Ia, Ib or Ic wherein X.sup.1, X.sup.2, X.sup.3 and X.sup.4 are all carbon and W is C(.dbd.O)NH can be prepared from appropriately substituted 4-, 5-, 6-, or 7-alkoxycarbonyl indazoles, IIIa, wherein R is an alkyl group such as methyl, ethyl or tert-butyl. ##STR42##
The requisite indazoles can be conveniently prepared from the commercially available nitrotoluic acids according to the example shown in Scheme 1. Conversion of the acid 1a to a suitable ester, such as the ethyl ester 1b, may be carried out by one of many methods well-known to one skilled in the art of organic synthesis, for example treatment with a suitable base, such as sodium bicarbonate, in a suitable solvent, such as N,N-dimethylformamide, followed by treatment with an alkyl halide, such as iodoethane. Reduction of the nitro group of 1b can be effected in a number of ways known to one skilled in the art of organic synthesis, including treatment with tin(II) chloride in ethanol. The resulting aniline derivative can be converted to the desired substituted indazole IIIa according to the method of Bartsch and Yang (J. Heterocycl. Chem. 1984, 21(4): 1063-1064). A variation of the conversion of the aniline 1c to the indazole IIIa proceeds through an N-acylated intermediate 1d followed by cyclization and deacetylation, according to the method reported by Ruchardt and Hassmann (Liebigs Ann. Chem. 1980, 908-927).
The order of the esterification and reduction steps may be reversed, such that the nitrotoluic acid is first converted to an aminotoluic acid, which is then esterified. In some cases other intermediates related to those shown in Scheme 1 are commercially available or may be prepared using methods described in the literature of organic chemistry; in these cases transformations similar to those shown in Scheme 1 may be used to prepare the desired compounds IIIa. For example, commercially available methyl 3-amino-4-methylbenzoate may be directly transformed into 6-methoxycarbonylindazole. ##STR43##
Compounds of Formula Ia or Ib wherein one or more of X.sup.1, X.sup.2, X.sup.3 or X.sup.4 are nitrogen may be prepared from the corresponding alkoxycarbonylindazoles IIIb in which the appropriate carbon atom or atoms have been replaced by nitrogen. These may in turn be prepared by substitution of the appropriately substituted heterocycle for the nitrotoluic acids, nitrotoluic acid esters, or aminotoluic acid esters in Scheme 1 above. The starting heterocycles could be obtained by following the procedures and methods in references outlined below, along with implementation of standard functional group transformations well known to one skilled in the art. ##STR44##
Functionalized pyrazines could be prepared according to procedures outlined in The Chemistry of Heterocyclic Compounds: The Pyrazines, Vol. 41 (Arnold Weissberger and Edward C. Taylor, Eds.),. John Wiley and Sons (New York: 1982). Preparation of appropriately functionalized pyridazines could be achieved using the methods described in The Chemistry of Heterocyclic Compounds: Condensed Pyridazines Including Cinnolines and Phthalazines, Vol. 27 (Arnold Weissberger and Edward C. Taylor, Eds.), John Wiley and Sons (New York: 1973) and The Chemistry of Heterocyclic Compounds: Pyridazines, Vol. 28 (Arnold Weissberger and Edward C. Taylor, Eds.), John Wiley and Sons (New York: 1973). For the synthesis of functionalized pyrimidines one could follow procedures in The Chemistry of Heterocyclic Compounds: The Pyrimidines, (Arnold Weissberger, Consulting Ed.) John Wiley and Sons (New York: 1962), The Chemistry of Heterocyclic Compounds: The Pyrimidines, Supplement I, (Arnold Weissberger and Edward C. Taylor, Consulting Eds.) John Wiley and Sons (New York: 1970), and The Chemistry of Heterocyclic Compounds: The Pyrimidines, Supplement II, Vol. 16 (Arnold Weissberger and Edward C. Taylor, Consulting Eds.) John Wiley and Sons (New York: 1985). Functionalized pyridines which can serve as starting materials in Scheme 1 could be made by the methods described in The Chemistry of Heterocyclic Compounds: Pyridine and Its Derivatives, Part Four, (Arnold Weissberger, Consulting Ed.) John Wiley and Sons (New York: 1964), The Chemistry of Heterocyclic Compounds: Pyridine and Its Derivatives, Supplement Part Two, (Arnold Weissberger and Edward C. Taylor, Consulting Eds.) John Wiley and Sons (New York: 1974), The Chemistry of Heterocyclic Compounds: pyridine and Its Derivatives, Supplement Part Three, Vol. 14 (Arnold Weissberger and Edward C. Taylor, Consulting Eds.) John Wiley and Sons (New York: 1974), The Chemistry of Heterocyclic Compounds: Pyridine and Its Derivatives, Supplement Part Four, Vol. 14 (Arnold Weissberger and Edward C. Taylor, Consulting Eds.) John Wiley and Sons (New York: 1975), and The Chemistry of Heterocyclic Compounds: Pyridine and Its Derivatives, Part Five, Vol. 14 (Arnold Weissberger and Edward C. Taylor, Consulting Eds.) John Wiley and Sons (New York: 1984). One example of the preparation of an appropriately substituted pyridine starting material is the preparation of 2-methyl-3-aminopyridine-5-carboxylic acid half-sulfate salt, as described by Argoudelis and Kummerow (J. Org. Chem. 1961, 26: 3420-3422).
Compounds of Formula Ia wherein R.sup.10 is not hydrogen may be prepared from appropriately substituted alkoxycarbonylindazoles. Some such substituted alkoxycarbonylindazoles may be prepared using the method outlined in Scheme 1. For example, methyl 4-amino-3-ethylbenzoate may be prepared as described by Witte and BoekeOheide (J. Org. Chem. 1972, 37 (18): 2849-2853) This compound may be converted to the diazonium fluoroborate and cyclized to 3-methyl-2-methoxycarbonylindazole using the method outlined in Scheme 1. This compound may be used as a starting material for preparation of the corresponding compounds of Formula Ia wherein R.sup.10 is methyl.
Other substituted alkoxycarbonylindazoles may be prepared from unsubstituted alkoxycarbonylindazoles using the methods outlined in Scheme 2. For example, an ethoxycarbonylindazole may be brominated by treatment with bromine in a suitable solvent, such as acetic acid, to provide the corresponding 3-bromo-ethoxycarbonyl-indazole IIIc. This compound may be coupled with a suitable reagent, alternatively followed by additional synthetic manipulations, to provide the desired 3-substituted-ethoxycarbonylindazole. For example, coupling with phenylboronic acid in the presence of tetrakis-(triphenylphosphine)palladium and triethylamine in N,N-dimethylformamide, using the method of Miyaura, Suginome and Suzuki (Tetrahedron 1983, 2: 3271) provides the corresponding 3-phenyl-ethoxycarbonylindazole IIId. Similar methods, starting from compounds of Formula IIIb, may be used to prepare the corresponding compounds wherein one or more of the ring carbons (corresponding to those designated X.sup.1, X.sup.2, X.sup.3 and X.sup.4 in Formula Ia) are replaced by nitrogen. ##STR45##
As another example, also shown in Scheme 2, coupling of IIIc with phenylacetylene in the presence of bis-(triphenylphosphine)palladium(II) chloride, copper(I) chloride, and triethylamine in pyridine according to the method of Melissaris and Litt (J. Org. Chem. 1992, 57: 6998-6999) provides the corresponding 3-(2-phenylethynyl)-ethoxycarbonylindazole IIIe, which may be reduced using hydrogen in the presence of palladium on charcoal to provide the corresponding 3-(2-phenyl-ethyl)ethoxycarbonylindazole IIIf. Similar methods, starting from compounds of Formula IIIb, may be used to prepare the corresponding compounds wherein one or more of the ring carbons (corresponding to those designated X.sup.1, X.sup.2, X.sup.3 and X.sup.4 in Formula Ia) are replaced by nitrogen.
Compounds IIIc, IIId, IIIe and IIIf may be used in the preparation of compounds of Formula Ia in which R.sup.10 is phenyl, 2-phenylethynyl, or 2-phenylethyl, respectively. Alternatively, further manipulations of the substituent may be accomplished at a later stage in the synthesis of the compound of Formula Ia. For example, the 2-phenylethynyl indazoles IIIe may be used in a synthetic sequence during the course of which the acetylene will be reduced, providing ultimately compounds of Formula Ia in which R.sup.10 is 2-phenylethyl.
Other appropriately substituted alkoxycarbonylindazoles, for use in the preparation of compounds of Formula Ia wherein R.sup.10 is not hydrogen, may be prepared using other methods known in the art of organic synthesis, such as those outlined in The Chemistry of Heterocyclic Compounds: Pyrazoles, Pyrazolines, Pyrazolidines, Indazoles and Condensed Rings, Vol. 22 (Arnold Weissberger, Ed.), John Wiley and Sons (New York: 1967), Chapter 10.
Hereinafter, unless otherwise specified, phrases such as "indazoles III" and "indazoles of Formula III" are meant to include simple indazoles IIIa, mono- or diazaindazoles IIIb, and substituted indazoles such as but not restricted to IIIc, IIId, IIIe and IIIf. Substituted mono- and diazaindazoles such as but not restricted to mono- and diaza analogs of IIIc, IIId, IIIe and IIIf are also included.
Compounds of Formula Ia may be prepared from indazoles III as outlined in Scheme 3. Alkylation of the indazoles of Formula III with a suitably functionalized alkyl halide can be effected in a variety of ways known to one skilled in the art. For example, using a method similar to that described by Granger et al. (Chim. Ther. 1970, 5: 24), an indazole of Formula III is treated with a suitable base, such as potassium bis(trimethylsilyl) amide, followed by addition of the alkyl halide, for example, 3-bromopropylphthalimide. Alternately, the alkylation can be carried out utilizing Mitsunobu conditions (Mitsunobu, Synthesis, 1981, 1-28) by addition of the corresponding alcohol, 3-hydroxypropylphthalimide, to a mixture of diethyl azodicarboxylate and triphenylphosphine in a suitable solvent, usually dry tetrahydrofuran, followed by addition of the indazole III. Separation, if necessary, of the mixture of 1- and 2-substituted isomers by chromatography provides the desired 1-alkylated product 3a. Removal of the phthalimide may be achieved by treatment with anhydrous hydrazine to give the primary amine 3b. ##STR46##
As further shown in Scheme 3,2-imidazolinyl-aminoalkylindazoles may be prepared by treatment of the amine 3b with a suitable reagent such as 2-methylthio-4,5-dihydroimidazolium iodide. Hydrolysis of the ester, using conventional methods known to one skilled in the art of organic synthesis, may be followed by coupling of the resulting acid to an appropriately substituted .alpha.- or .beta.-amino ester such as a compound of Formula IV, to provide an intermediate which, after deprotection, affords compounds of Formula Ia wherein R.sup.1 is 2-imidazolinylaminoalkyl. The coupling may be carried out using any of the many methods for the formation of amide bonds known to one skilled in the art of organic synthesis. Those methods include, but are not limited to, use of standard coupling procedures such as the azide method, mixed carbonic acid anhydride (isobutyl chloroformate) method, carbodiimide (dicyclohexylcarbodiimide, diisopropylcarbodiimide, or water-soluble carbodiimides (WSCDI)) method, active ester (p-nitrophenyl ester, N-hydroxysuccinic imido ester) method, or by the use of one of many other known coupling reagent such as BOP-Cl. Some of these methods (especially the carbodiimide method) can be enhanced by the addition of 1-hydroxybenzotriazole to the reaction mixture.
An alternative method for preparing amines 3b wherein n=3 is outlined in Scheme 4. Alkylation of the indazole III may be achieved by treatment with an optionally substituted acrylonitrile in the presence of a catalytic amount of a base such as sodium ethoxide or sodium bis(trimethylsilyl)amide, in a suitable solvent such as ethanol, to provide the intermediate nitrile 4a. This may be converted to the amine 3b by reduction using any of a number of methods known to one skilled in the art of organic synthesis, such as by treatment with hydrogen in the presence of a catalyst such as palladium on charcoal. An acid such as aqueous hydrochloric acid may be added to the reaction mixture to minimize side reactions during the reduction. ##STR47##
Appropriately substituted racemic .beta.-amino acids IV (used in Scheme 3) may be purchased commercially or, as is shown in Scheme 5, Method 1, prepared from the appropiate aldehyde, malonic acid and ammonium acetate according to the procedure of Johnson and Livak (J. Am. Chem. Soc., 1936, 58, 299). Racemic .beta.-substituted-.beta.-amino esters may be prepared through the reaction of dialkylcuprates or alkyllithiums with 4-benzoyloxy-2-azetidinone followed by treatment with anhydrous ethanol (Scheme 5, Method 2) or by reductive amination of .beta.-keto esters as is described in WO93/16038 (also see Rico et al., J. Org. Chem., 1993, 58, 7948-51). Enantiomerically pure .beta.-substituted-.beta.-amino acids can be obtained through the optical resolution of the racemic mixture or can be prepared using numerous methods, including: Arndt-Eistert homologation of the corresponding .beta.-amino acids as shown in Scheme 5, Method 3 (see Meier and Zeller, Angew. Chem. Int. Ed. Engl., 1975 14, 32; Rodriguez et al., Tetrahedron Lett., 1990, (31), 5153; Greenlee, J. Med. Chem. 1985, 28, 434 and references cited within); and through an enantioselective hydrogenation of a dehydroamino acid as is shown in Scheme 5, Method 4 (see Asymmetric Synthesis, Vol. 5, (Morrison, ed.) Academic Press, New York: 1985). A comprehensive treatise on the preparation of .beta.-amino acid derivatives may be found in patent application WO 93/07867, the disclosure of which is hereby incorporated by reference. ##STR48##
The synthesis of N.sup.2 -substituted diaminopropionic acid derivatives IV can be carried out via Hoffmann rearrangement of a wide variety of asparagine derivatives as described, for example, by Waki et al. (Synthesis 1981, 266-267) or by Moore et al. (J. Med. Chem. 1976, 19(6), 766-772). An example is shown in Scheme 6, Method 1. They may also be prepared by manipulations, which will be familiar to one skilled in the art of organic synthesis, of the commercially available 3-amino-2-benzyloxycarbonylaminopropionic acid. An example is shown in Scheme 6, Method 2. ##STR49##
Compounds of Formula Ia above wherein R.sup.1 is 2-pyridinylaminoalkyl may be prepared by the method outlined in Scheme 7. Treatment of the intermediate aminoalkylindazole 3b from Scheme 3 (or the corresponding salt from Scheme 4) with 2-chloropyridine N-oxide hydrochloride, using a modification of the method described by Misra, et al. (Bioorg. and Med. Chem. Letters, 1994, 4, 2165-2170), and subsequent reduction of the resulting N-oxide derivative 7a provides a 2-pyridinylaminoalkyl intermediate 7b. This reduction may be performed using a number of methods known to one skilled in the art of organic synthesis, such as that using ammonium formate in the presence of 10% palladium on charcoal in refluxing ethanol, as described by Balicki (Synthesis, 1989, 645-646), or by reduction with hydrogen in the presence of a catalyst such as palladium on charcoal or Raney nickel, or by treatment with triphenylphosphine. The resulting 2-aminopyridine moiety of 7b may be optionally protected, for example by treatment with di-t-butyldicarbonate in dry tetrahydrofuran in the presence of a suitable base, such as triethylamine or N,N-dimethylaminopyridine, using the method of Iwanowicz (Synth. Commun., 1993, 23(10), 1443-1445), to provide intermediate 7c. Ester hydrolysis, coupling and deprotection as outlined in Scheme 3 can then provide the desired compounds of Formula Ia. ##STR50##
An alternative route to 1-(heteroarylaminoalkyl)indazoles of Formula Ia is outlined in Scheme 8. A suitable indazole III can be alkylated with an alkyl halide bearing a protected aldehyde, such as a 1,3-dioxolane, using conditions described above (see Scheme 3) to provide 8a. Deprotection to the aldehyde 8b, for example by treatment with aqueous acid, may be followed by reductive amination with a heteroarylamine such as 2-aminopyridine or a suitably protected 2-aminoimidazole, such as 1-triphenylmethyl-2-aminoimidazole, in the presence of a reducing agent such as sodium triacetoxyborohydride or sodium cyanoborohydride, to provide the 1-(heteroarylaminoalkyl)indazole 8c. The intermediates 8c can then be elaborated to the corresponding compounds of Formula Ia, for example as described in Scheme 3. ##STR51##
A route to 1-(heteroarylaminocarbonylethyl) 10 indazoles of Formula Ia is outlined in Scheme 9. A suitable indazole III can be alkylated by treatment with an acrylic acid ester such as tert-butyl acrylate, using a method such as that described in Scheme 4. Removal of the ester of 9a may be followed by conversion to a heteroaryl amide by treatment with a heteroaryl amine using any of a number of methods well known to one skilled in the art of organic synthesis. The resulting 1-(heteroarylaminocarbonylethyl)indazole 9b can then be elaborated to the corresponding compounds of Formula Ia, for example as described in Scheme 3. ##STR52##
Compounds of Formula Ib may be prepared according to the method outlined in Scheme 10. Thus, the appropriate indazole III may be alkylated by treatment with a suitable base, for example sodium hydride, followed by addition of a suitable alkylating agent such as an alkyl halide R.sup.9 -Br or R.sup.9 -I. Bromination of the intermediate 10a using, for example, bromine in acetic acid, provides the corresponding 3-bromo derivative 10b. (The order of these two synthetic steps may also be reversed. That is, the indazole III may be brominated, and resulting bromoindazole may be alkylated, to provide similar products 10b.) Coupling of 10b with, for example, 3,3-diethoxy-1-propyne, under conditions similar to those described by Sakamoto et al. (Synthesis 1992, 746-748) provides a functionallzed alkynyl derivative 10c. Reduction of the acetylenic bond of 10c using, for example, hydrogen in the presence of a catalyst such as palladium on charcoal, followed by hydrolysis of the acetal with aqueous acid provides an aldehyde intermediate 10d which, using methods analogous to those outlined in Scheme 8, may be elaborated to an intermediate 10e containing a heteroarylaminoalkyl substituent at the 3-position. This intermediate may then in turn be elaborated to the desired compounds of Formula Ib, for example using methods described in Scheme 3. ##STR53##
Compounds of Formula Ib may alternatively be prepared from the intermediate 10b to the method described in Scheme 11. Thus,coupling of 10b under conditions similar to those described by Murakami et al. (Heterocycles, 1990, 31(8), 1505-11) can provide a 3-allyl derivative 11a. Hydroboration as described by Brown and Subba Rao (J. Am. Chem. Soc. 81, 6428-6433) can provide the alcohol 11b, which may be subjected to the Mitsunobu reaction (vide supra) with phthalimide followed by deprotection to provide an amine intermediate 11c which, analogously to the method shown in Schemes 10 and 3, can be elaborated to the desired compounds of Formula Ib. Alternatively, the intermediate 11b may be prepared by reduction of the aldehyde 10d shown in Scheme 10. Other methods can be used for the conversion of intermediates 10d and 11b to the primary amine 10c which are known to those skilled in the art of organic synthesis. ##STR54##
Compounds of Formula Ic may be prepared according to methods outlined in Scheme 12. Treatment of the appropriate indazole starting material 12a with zinc bromide and vinylmagnesium bromide followed by dichloro1,1'-bis(diphenylphosphino)ferrocene! palladium (II), using a procedure similar to that described by Brown, et al. (U.S. Pat. No. 4,898,863), can provide the desired 3-vinyl derivative 12b. Treatment of this compound with ozone (F. J. Brown, et al. Ibid.), can provide an aldehyde 12c. Oxidation using silver(I) oxide, as described by Campaigne and LeSuer (Organic Syntheses, 1963, Coll. Vol. 4, 919), can provide the desired carboxylic acid 12d. Esterification and deprotection of the ether oxygen of 12e using boron tribromide, by a method analogous to that detailed by Manson and Musgrave (J. Chem. Soc. 1011 (1963)), can provide the hydroxy intermediate 12f. Mitsunobu coupling, (vide supra), followed by further transformations of 12g similar to those shown in Scheme 3, can provide compounds of Formula Ic. ##STR55##
Additional alcohols useful for the preparation of compounds of Formula Ia, Ib and Ic through the Mitsunobu reaction described in the above schemes may be prepared as described in Scheme 13. ##STR56##
Various compounds of Formula Ia, Ib or Ic may be prepared from a common derivative of the corresponding compounds of Formula Ia, Ib or Ic by functional group manipulations familiar to one skilled in the art of organic synthesis. As one example, preparation of compounds of Formula Ia having different sulfonamide substituents at R.sup.16 may be achieved as outlined in Scheme 14. Thus, the compound of Formula Ia having a benzyloxycarbonylamino group at R.sup.16 (14a) may be hydrogenolyzed using, for example, hydrogen in the presence of a catalyst such as palladium on charcoal to provide the primary amine derivative 14b. This may be reacted with a sulfonylating agent such as R.sup.17 SO.sub.2 Cl in the presence of an amine such as triethylamine to provide, after deprotection of the ester, the desired compound of Formula Ia. In place of the sulfonyl chloride, use of a carboxylic acid, acid chloride or acid anhydride can provide the corresponding amide derivative, use of a chloroformate can provide the corresponding carbamate derivative, use of a sulfamoyl chloride can provide the corresponding sulfamide derivative, and use of an isocyanate can provide the corresponding urea derivative. ##STR57##
As another example, compounds of Formula Ia with different variations in R.sup.1 may be prepared from a common precursor as outlined in Scheme 15. Thus, the amine intermediate 3b may be reacted, for example, with benzyl chloroformate to provide the benzyl carbamate. Hydrolysis of the ester, for example with lithium hydroxide, can provide the acid intermediate 15a. Using methods described earlier, 15a may be reacted with, for example, a suitable beta-amino ester, followed by removal of the benzyl carbamate, for example by hydrogenolysis, to provide the amine intermediate 15b. Using, for example, steps analogous to those shown in Schemes 3 or 7, the amine may be converted to an aminoheterocyclic group. After deprotection of the ester, the desired compound of Formula Ia may be obtained. ##STR58##
The example outlined in Scheme 15 will also serve to demonstrate that the order in which the different substituents are elaborated to give the compounds of Formula Ia, Ib and Ic may be varied from that in the examples shown in Schemes 1 through 14. This example will also serve to demonstrate the use of protecting groups to temporarily protect a functional group in the course of a synthetic sequence when that functional group is not compatible with one or more of the synthetic transformations that are to be accomplished. Such use of protecting groups, while not always explicitly shown in Schemes 1 through 15, is well known to one skilled in the art of organic synthesis. Many examples of protecting groups may be found, for example, in Greene, "Protective Groups in Organic Syntheses", Wiley (New York), 1981.
The detailed processes for preparing the compounds of Formula Ia, Ib or Ic are illustrated by the following Examples. It is, however, understood that this invention is not limited to the specific details of these examples. Reactions were run under an atmosphere of nitrogen unless otherwise indicated. Solvent removal from reaction mixtures, extracts, and the like was performed under vacuum on a rotary evaporator. Flash chromatography refers to the medium-pressure column chromatography method described by Still et al. (J. Org. Chem. 1978, 43(14), 2923-2925). Melting points (mp) are uncorrected. Proton nuclear magnetic resonance spectra (NMR) were measured in chloroform-d (CDCl.sub.3), dimethyl sulfoxide-d.sub.6 (DMSO-d.sub.6) or methanol-d.sub.4 (MeOH-d.sub.4) and the peaks are reported in parts per million downfield from tetramethylsilane (.delta.). The coupling patterns are reported as follows: s, singlet; d, doublet; t, triplet; q, quartet; m, multiplet; b, broad. Mass spectra were measured using electrospray ionization (ESI),. ammonia chemical ionization (NH.sub.3 --CI), fast-atom bombardment from a glycol matrix (FAB), or electron impact ionization (EI).

Using the methods described above and modifications thereof known to one skilled in the art of organic synthesis, the following additional examples in Tables 1-8 can be prepared.
UTILITY
The compounds of Formula Ia, Ib or Ic of the present invention possess activity as antagonists of integrins such as, for example, the .alpha..sub.v .beta..sub.3 or vitronectin receptor, .alpha..sub.v .beta..sub.5 or .alpha..sub.5 .beta..sub.1, and as such have utility in the treatment and diagnosis of cell adhesion, angiogenic disorders, inflammation, bone degradation, cancer metastases, diabetic retinopathy, thrombosis, restenosis, macular degeneration, and other conditions mediated by cell adhesion and/or cell migration and/or angiogenesis. The integrin antagonist activity of the compounds of the present invention is demonstrated using assays which measure the binding of a specific integrin to a native ligand, for example, using the ELISA assay described below for the binding of vitronectin to the .alpha..sub.v .beta..sub.3 receptor.
The compounds of the present invention possess selectivity for the .alpha..sub.v .beta..sub.3 receptor relative to the GPIIb/IIIa receptor as demonstrated by their reduced activity in standard assays of platelet aggregation, such as the platelet aggregation assay described below.
One of the major roles of integrins in vivo is to mediate cellular interactions with adjacent cells. Cell based adhesion assays can be used to mimic these interactions in vitro. A cell based assay is more representative of the in vivo situation than an ELISA since the receptor is maintained in membranes in the native state. The compounds of the present invention have activity in cell-based assays of adhesion, for example as demonstrated in using the cell adhesion assays described below.
The compounds of Formula Ia, Ib or Ic of the present invention may be useful for the treatment or prevention of other diseases which involve cell adhesion processes, including, but not limited to, osteoporosis, rheumatoid arthritis, autoimmune disorders, bone degradation, rheumatoid arthritis, asthma, allergies, adult respiratory distress syndrome, graft versus host disease, organ transplantation, septic shock, psoriasis, eczema, contact dermatitis, osteoarthritis, atherosclerosis, metastasis, wound healing, inflammatory bowel disease and other angiogenic disorders.
The compounds of Formula Ia, Ib or Ic have the ability to suppress/inhibit angiogenesis in vivo, for example, as demonstrated using animal models of ocular neovascularization.
The compounds provided by this invention are also useful as standards and reagents in determining the ability of a potential pharmaceutical to inhibit integrin-ligand binding. These may be provided in a commercial kit comprising a compound of this invention.
As used herein ".mu.g" denotes microgram, "mg" denotes milligram, "g" denotes gram, ".mu.L" denotes microliter, "mL" denotes milliliter, "L" denotes liter, "nM" denotes nanomolar, ".mu.M" denotes micromolar, "mM" denotes millimolar, "M" denotes molar and "nm" denotes nanometer. "Sigma" stands for the Sigma-Aldrich Corp. of St. Louis, Mo.
The utility of the compounds of the present invention may be assessed by testing in one or more of the following assays as described in detail below: Purified .alpha..sub.v .beta..sub.3 (human placenta)--Vitronectin ELISA, .alpha..sub.v .beta..sub.3 -Vitronectin Binding Assay, Human Aortic Smooth Muscle Cell Migration Assay, In Vivo Angiogenesis Model, Pig Restenosis Model, Mouse Retinopathy Model. A compound of the present invention is considered to be active if it has an IC.sub.50 or K.sub.i value of less than about 10 .mu.M for the inhibition of .alpha..sub.v .beta..sub.3 -Vitronectin Binding Assay, with compounds preferably having K.sub.i values of less than about 0.1 .mu.M. Tested compounds of the present invention are active in the .alpha..sub.v .beta..sub.3 -Vitronectin Binding Assay.
Purified .alpha..sub.v .beta..sub.3 (human placenta)--Vitronectin ELISA
The .alpha..sub.v .beta..sub.3 receptor was isolated from human placental extracts prepared using octylglucoside. The extracts were passed over an affinity column composed of anti-.alpha..sub.v .beta..sub.3 monoclonal antibody (LM609) bound to Affigel. The column was subsequently washed extensively at pH 7 and pH 4.5 followed by elution at pH 3. The resulting sample was concentrated by wheat germ agglutinin chromatography to provide two bands by SDS gel electrophoresis which were confirmed as .alpha..sub.v .beta..sub.3 by western blotting.
Affinity purified protein was diluted at different levels and plated to 96 well plates. ELISA was performed using fixed concentration of biotinylated vitronectin (approximately 80 nM/well). This receptor preparation contains the .alpha..sub.v .beta..sub.3 with no detectable levels of .alpha..sub.v .beta..sub.5 according to the gel and according to effects of blocking antibodies for the .alpha..sub.v .beta..sub.3 or .alpha..sub.v .beta..sub.5 integrins in the ELISA.
A submaximal concentration of biotinylated vitronectin was selected based on a concentration response curve with fixed receptor concentration and variable concentrations of biotinylated vitronectin.
.alpha..sub.v .beta..sub.3 -Vitronectin Binding Assay
The purified receptor is diluted with coating buffer (20 mM Tris HCl, 150 mM NaCl, 2.0 mM CaCl.sub.2, 1.0 mM MgCl.sub.2.6H.sub.2 O, 1.0 mM MnCl.sub.2.4H.sub.2 O) and coated (100 .mu.L/well) on Costar (3590) high capacity binding plates overnight at 4.degree. C. The coating solution is discarded and the plates washed once with blocking/binding buffer (B/B buffer, 50 mM Tris HCl, 100 mM NaCl, 2.0 mM CaCl.sub.2, 1.0 mM MgCl.sub.2.6H.sub.2 O, 1.0 mM MnCl.sub.2.4H.sub.2 O). Receptor is then blocked (200 .mu.L/well) with 3.5% BSA in B/B buffer for 2 hours at room temperature. After washing once with 1.0 % BSA in B/B buffer, biotinylated vitronectin (100 .mu.L) and either inhibitor (11 .mu.L) or B/B buffer w/1.0% BSA (11 .mu.L) is added to each well. The plates are incubated 2 hours at room temperature. The plates are washed twice with B/B buffer and incubated 1 hour at room temperature with anti-biotin alkaline phosphatase (100 .mu.L/well) in B/B buffer containing 1.0 % BSA. The plates are washed twice with B/B buffer and alkaline phosphatase substrate (100 .mu.L) is added. Color is developed at room temperature. Color development is stopped by addition of 2N NaOH (25 .mu.L/well) and absorbance is read at 405 nm. The IC.sub.50 is the concentration of test substance needed to block 50% of the vitronectin binding to the receptor.
Integrin Cell-Based Adhesion Assays
In the adhesion assays, a 96 well plate was coated with the ligand (i.e., fibrinogen) and incubated overnight at 4.degree. C. The following day, the cells were harvested, washed and loaded with a fluorescent dye. Test compounds and cells were added together and then were immediately added to the coated plate. After incubation, loose cells are removed from the plate, and the plate (with adherent cells) is counted on a fluorometer. The ability of test compounds to inhibit cell adhesion by 50% is given by the IC.sub.50 value and represents a measure of potency of inhibition of integrin mediated binding. Compounds were tested for their ability to block cell adhesion using assays specific for .alpha..sub.v .beta..sub.3, .alpha..sub.v .beta..sub.5 and .alpha..sub.v .beta..sub.1 integrin interactions.
Platelet Aggregation Assay
Venous blood was obtained from anesthetized mongrel dogs or from healthy human donors who were drug- and aspirin-free for at least two weeks prior to blood collection. Blood was collected into citrated Vacutainer tubes. The blood was centrifuged for 15 minutes at 150.times.g (850 RPM in a Sorvall RT6000 Tabletop Centrifuge with H-1000 B rotor) at room temperature, and platelet-rich plasma (PRP) was removed. The remaining blood was centrifuged for 15 minutes at 1500.times.g (26,780 RPM) at room temperature, and platelet-poor plasma (PPP) was removed. Samples were assayed on a PAP-4 Platelet Aggregation Profiler, using PPP as the blank (100% transmittance). 200 .mu.L of PRP (5.times.10.sup.8 platelets/mL) were added to each micro test tube, and transmittance was set to 0%. 20 .mu.L of ADP (10 .mu.M) was added to each tube, and the aggregation profiles were plotted (% transmittance versus time). Test agent (20 .mu.L) was added at different concentrations prior to the addition of the platelet agonist. Results are expressed as % inhibition of agonist-induced platelet aggregation.

Dosage and Formulation
The compounds of this invention can be administered by any means that produces contact of the active agent with the agent's site of action, the .alpha..sub.v .beta..sub.3 integrin, in the body of a mammal. They can be administered by any conventional means available for use in conjunction with pharmaceuticals, either as individual therapeutic agents or in a combination of therapeutic agents, such as a antiplatelet agent such as aspirin, piroxicam, or ticlopidine which are agonist-specific, or an anti-coagulant such as warfarin or heparin, or a thrombin inhibitor such as a boropeptide, hirudin or argatroban, or a thrombolytic agent such as tissue plasminogen activator, anistreplase, urokinase or streptokinase, or combinations thereof. The compounds of the invention, or compounds of the invention in combination with other therapeutic agents, can be administered alone, but generally administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.
The dosage of the novel compounds of this invention administered 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 age, health and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; and the effect desired. A daily dosage of active ingredient can be expected to be about 0.001 to 10 milligrams per kilogram of body weight.
Dosage forms (compositions suitable for administration) contain from about 0.1 milligram to about 100 milligrams of active ingredient per 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.
The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets, and powders, or in liquid dosage forms, such as elixirs, syrups, and suspensions. It can also be administered by injection, in sterile liquid dosage forms.
Gelatin capsules 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.
Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.
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.
Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.
Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows:
Capsules
A large number of unit capsules are prepared by filling standard two-piece hard gelatin capsules each with 10 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate.
Soft Gelatin Capsules
A mixture of active ingredient in a digestable oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 10 milligrams of the active ingredient. The capsules are washed and dried.
Tablets
A large number of tablets are prepared by conventional procedures so that the dosage unit was 10 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.
The combination products of this invention, such as the novel .alpha..sub.v .beta..sub.3 antagonist compounds of this invention in combination with an anti-coagulant agent such as warfarin or heparin, or an anti-platelet agent such as aspirin, piroxicam or ticlopidine, or a thrombin inhibitor such as a boropeptide, hirudin or argatroban, or a thrombolytic agent such as tissue plasminogen activator, anistreplase, urokinase or streptokinase, or combinations thereof, can be in any dosage form, such as those described above, and can also be administered in various ways, as described above.
In a preferred embodiment, the combination products of the invention are formulated together, in a single dosage form (that is, combined together in one capsule, tablet, powder, or liquid, etc.). When the combination products are not formulated together in a single dosage form, the .alpha..sub.v .beta..sub.3 antagonist compounds of this invention and the anti-coagulant agent, anti-platelet agent, thrombin inhibitor, and/or thrombolytic agent may be administered at the same time (that is, together), or in any order, for example the compounds of this invention are administered first, followed by administration of the anti-coagulant agent, anti-platelet agent, thrombin inhibitor, and/or thrombolytic agent. When not administered at the same time, preferably the administration of the compound of this invention and any anti-coagulant agent, anti-platelet agent, thrombin inhibitor, and/or thrombolytic agent occurs less than about one hour apart, more preferably less than about 30 minutes apart, even more preferably less than about 15 minutes apart, and most preferably less than about 5 minutes apart. Preferably, administration of the combination products of the invention is oral. The terms oral agent, oral inhibitor, oral compound, or the like, as used herein, denote compounds which may be orally administered. Although it is preferable that the .alpha..sub.v .beta..sub.3 antagonist compounds of this invention and the anti-coagulant agent, anti-platelet agent, thrombin inhibitor, and/or thrombolytic agent are both administered in the same fashion (that is, for example, both orally), if desired, they may each be administered in different fashions (that is, for example, one component of the combination product may be administered orally, and another component may be administered intravenously). The dosage of the combination products of the invention may vary depending upon various factors such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration, the age, health and weight of the recipient, the nature and extent of the symptoms, the kind of concurrent treatment, the frequency of treatment, and the effect desired, as described above.
As discussed above, where two or more of the foregoing therapeutic agents are combined or co-administered with the compounds of this invention, 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 which would be obtained as a result of addition of further agents in accordance with the present invention.
Particularly when provided as a single dosage form, the potential exists for a chemical interaction between the combined active ingredients (for example, a novel compound of this invention and an anti-coagulant such as warfarin or heparin, or a novel compound of this invention and an anti-platelet agent such as aspirin, piroxicam or ticlopidine, or a novel compound of this invention and a thrombin inhibitor such as a boropeptide, hirudin or argatroban, or a novel compound of this invention and a thrombolytic agent such as tissue plasminogen activator, anistreplase, urokinase or streptokinase, or combinations thereof). For this reason, the preferred dosage forms of the combination products of this invention are formulated such that although the active ingredients are combined in a single dosage form, the physical contact between the active ingredients is minimized (that is, reduced).
In order to minimize contact, one embodiment of this invention where the product is orally administered provides for a combination product wherein one active ingredient is 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. Another embodiment of this invention where oral administration is desired provides for a combination product wherein one of the active ingredients is coated with a sustained-release 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 low viscosity 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.
Dosage forms of the combination products of the present invention wherein one active ingredient is enteric coated can be in the form of tablets such that the enteric coated component and the other active ingredient are blended together and then compressed into a tablet or such that the enteric coated component is compressed into one tablet layer and the other active ingredient is compressed into an additional layer. Optionally, in order to further separate the two layers, one or more placebo layers may be present such that the placebo layer is between the layers of active ingredients. In addition, dosage forms of the present invention can be in the form of capsules wherein one active ingredient is compressed into a tablet or in the form of a plurality of microtablets, particles, granules or non-perils, which are then enteric coated. These enteric coated microtablets, particles, granules or non-perils are then placed into a capsule or compressed into a capsule along with a granulation of the other active ingredient.
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.
Pharmaceutical kits useful in, for example, the inhibition of thrombus formation, the prevention of blood clots, and/or the treatment of thromboembolic disorders, which comprise a therapeutically effective amount of a compound according to the method of the present invention along with a therapeutically effective amount of an anti-coagulant agent such as warfarin or heparin, or an antiplatelet agent such as aspirin, piroxicam or ticlopidine, or a thrombin inhibitor such as a boropeptide, hirudin or argatroban, or a thrombolytic agent such as tissue plasminogen activator, anistreplase, urokinase or streptokinase, or combinations thereof, in one or more sterile containers, are also within the ambit of the present invention. Sterilization of the container may be carried out using conventional sterilization methodology well known to those skilled in the art. The sterile containers of materials may comprise separate containers, or one or more multi-part containers, as exemplified by the UNIVIALTM.TM. two-part container (available from Abbott Labs, Chicago, Illinois), as desired. The compounds according to the method of the invention and the anti-coagulant agent, anti-platelet agent, thrombin inhibitor, thrombolytic agent, and/or combinations thereof, may be separate, or combined into a single dosage form as described above. Such kits may further include, if desired, one or more of various conventional pharmaceutical kit components, such as for example, one or more pharmaceutically acceptable carriers, additional vials for mixing the components, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, may also be included in the kit.
