Description: TITLE ISOXAZOLINE AND ISOXAZOLE DERIVATIVES AS INTEGRIN RECEPTOR ANTAGONISTS FIELD OF THE INVENTION 0 This invention relates to novel heterocycles which are useful as antagonists of the α v β 3 and related integrin receptors, to pharmaceutical compositions containing such compounds, processes for preparing such compounds, and to methods of using these compounds, 5 alone or in combination with other therapeutic agents, for the inhibition of cell adhesion and the treatment of angiogenic disorders, inflammation, bone degradation, tumors, metastases, thrombosis, and other cell aggregation-related conditions. 0 BACKGROUND OF THE INVENTION Angiogenesis or neovascularization is critical for normal physiological processes such as embryonic 5 development and wound repair (Folkman and Shing, J. Biol. Chem. 1992, 267 :10931-10934; D'Amore and Thompson, Ann. Rev. Physiol. 1987, 9_:453-464) . However, angiogenesis occurs pathologically, for example, in ocular neovascularization (leading to diabetic 0 retinopathy, neovascular glaucoma, retinal vein occlusion and blindness) , in rheumatoid arthitis and in solid tumors (Folkman and Shing, J. Biol. Chem., 1992, 267 :10931-10934; Blood and Zetter, Biochim. Biophys. Acta., 1990, 1032:118-128) . 5 Tumor dissemination, or metastasis, ' involves several distinct and complementary components, including the penetration and transversion of tumor cells through basement membranes and the establishment of self- sustaining tumor foci in diverse organ systems. To this end, the development and proliferation of new blood vessels, or 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, 7_9. :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 α v β 3 is preferentially expressed on angiogenic blood vessels in chick and man (Brooks et al., Science, 1994, 264;569-57l; Enenstein and Kramer, J. Invest. Dermatol., 1994, 103;381-386). Integrin α v β 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, ό9_:ll-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 α v β 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 α v β 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 α v /β 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, smooth muscle cell migration and, therefore, may play a fundamental role in vascular cell biology. . Recently, an antibody to the o v β 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 α v β 3 integrin induced apoptosis of the proliferating angiogenic vascular cells, leaving pre-existing quiescent blood vessels unaffected. Thus, α v β 3 integrin antagonists have been shown to inhibit angiogenesis. Based on this property, therapeutic utility of such agents is expected in human diseases such as cancer, 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. These receptors belong to a gene superfamily called integrins and are composed of heterodimeric transmembrane glycoproteins containing α- and β-subunits. Integrin subfamilies contain a common β-subunit combined with different α-subunits to form adhesion receptors with unique specificity. The genes for eight distinct β- subunits have been cloned and sequenced to date. Two members of the βi subfamily, α4/βιand αs/βi have been implicated in various inflammatory processes. Antibodies to α_ prevent adhesion of lymphocytes to synovial endothelial cells in vitro, a process which may be of importance in rheumatoid arthritis (VanDinther- Janssen et al., J. Immunol., 1991, 147:4207). Additional studies with monoclonal anti-α_ antibodies provide evidence that α_/βι may additionally have a role in allergy, asthma, and autoimmune disorders (Walsh et al., J. Immunol., 1991, 146:3419; Bochner et al., J. Exp. Med., 1991 173:1553; Yednock et al., Nature, 1992, 356:63). Anti-α4 antibodies also block the migration of leukocytes to the site of inflammation (Issedutz et al., J. Immunol., 1991, 147:4178). The α v /β 3 heterodimer is a member of the β 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 GPIIb/IIIa, the vitronectin receptor binds a variety of RGD-containing adhesive proteins such as vitronectin, fibronectin, VWF, fibrinogen, osteopontin, bone sialo protein II and thrombosponden 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 α v /β 3 receptor in this process and suggest that _ selective α v /β 3 antagonist would have utility in blocking bone resorption (Horton et al., J. Bone Miner. Res., 1993, 8:239-247; Helfrich et al. , J. Bone Miner. Res. , 1992, 7:335-343) .

The compounds of the present invention may also be used in diagnostic assays involving α v β 3 - 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=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 2 , R 4 , R 6 , R 7 , R 8 , R 12 ,and R 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 0-2 R 4 , then said group may optionally be substituted with up to two R 4 and R 4 at each occurrence is selected independently from the defined list of possible R 4 . Also, by way of example, for the group -N(R 5a ) 2 , each of the two R 5a substituents on N is independently selected from the defined list of possible R 5a . Similarly, by way of example, for the group -C(R 7 ) 2 -, each of the two R 7 substituents on C is independently selected from the defined list of possible R 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 I, 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 I 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., =0), then 2 hydrogens on the atom are replaced.

Lists of suitable salts are found in Remingto 's Pharmaceutical Sciences, 17th ed. , Mack Publishing Company, Easton, PA, 1985, p. 1418, the disclosure of which is hereby incorporated by reference. The disclosures of all of the references cited herein are hereby incorporated herein by reference in their entirety. 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 I wherein the central heterocycle is a 3,5-disubstituted isoxazoline ring can be conveniently prepared by dipolar cycloaddition of nitrile oxides with appropriate dipolarophiles (for reviews of 1,3-dipolar cycloaddition chemistry, see 1,3- Dipolar Cycloaddition Chemistry (Padwa, ed.), Wiley, New York, 1984; Kanemasa and Tsuge, Heterocycles 1990, 30, 719) . The requisite nitrile oxides are in turn prepared from the corresponding aldehydes via the intermediate oximes. Scheme I illustrates one synthetic sequence which will provide the 3, 5-isoxazolines of this invention. An appropriately substituted hydroxylamine is treated with NCS in DMF according to the method of Liu, et al. (J^ Org. Chem. 1980, _45_, 3916) . The resulting hydroximinoyl chloride is then dehydrohalogenated in situ using TEA to give a nitrile oxide, which undergoes a 1,3-dipolar cycloaddition to a suitably substituted alkene to afford the isoxazoline. Alternatively, the oxime may be oxidatively chlorinated, dehydrochlorinated and the resulting nitrile oxide trapped by a suitable alkene under phase transfer conditions according to the method of Lee (Synthesis 1982, 508) . Subsequent hydrolysis of the ester using conventional methods known to one skilled in the art of organic synthesis gives the desired acids. Coupling of the resulting acids to appropriately substituted - or β- amino esters affords an intermediate which can be deprotected to give compounds of Formula I. The coupling is carried out using any of the many methods for the formation of amide bonds known to one skilled in the art of organic synthesis. These methods include but are not limited to conversion of the acid to the corresponding acid chloride, or use of standard coupling procedures such as the azide method, mixed carbonic acid anhydride (isobutyl chloroformate) method, carbodiimide (dicyclohexylcarbodiimide, diisopropylcarbodiimide, or water-soluble carbodiimides) method, active ester (p- nitrophenyl ester, N-hydroxysuecinic imido ester) method, carbonyldiimidazole method, phosphorus reagents such as BOP-C1. Some of these methods (especially the carbodiimide) can be enhanced by the addition of 1- hydroxybenzotriazole.

The appropriately substituted racemic β-amino acids may be purchased commercially or, as is shown in Scheme II, Method 1, prepared from the appropriate aldehyde, malonic acid and ammonium acetate according to the procedure of Johnson and Livak (J. Am. Chem. Soc. 1936, 58, 299) . Racemic β-substituted-β-amino esters may be prepared through the reaction of dialkylcuprates or alkyllithiums with 4-benzoyloxy-2-azetidinone followed by treatment with anhydrous ethanol (Scheme I, Method 2) or by reductive amination of β-keto esters as is described in published PCT patent application WO9316038. (Also see Rico et al., J. Org. Chem. 1993, 5_8, 7948-51.) Enantiomerically pure β-substituted-β-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 α-amino acids as shown in Scheme II, Method 3 (see Meier, and Zeller, Angew, Chem.

Reduction of the azide by the action of triphenylphosphine in the presence of water ( for example see, Scriven, E. F.V. , Turnbull, K. , Chemical Rev. 1988, 88, 297-360, and the references therein ) provides an amine which is suitably protected, for example, Fmoc, Boc or phthalimide group according to literature procedures. (Protecting Groups in Organic Synthesis 2nd Ed. Green, T. W., Wits, P. G. M. pp 309-406. 1991 John Wiley & Sons, Inc. NY) Scheme ! b The appropriate nitroesters are available from commercial sources or can be synthesized according to literature methods (Seebach, D.et al . , Chem. Ber. 1982, 115, 1705-1720; Chaser. D.W., Syn . Comm . 1982, 841-842) . Additional methods for the preparation of compounds of the present invention containing the isoxazoline ring in the reverse orientaion are outlined in Scheme V. An appropriate ω-alkenol can be reacted with commercially available ethyl chorooxirrtidoacetate in a suitable solvent, such as tetrahydrofuran or methylene chloride, in the presence of a suitable base, such as aqueous sodium bicarbonate or triethylamine, to provide the isoxazoline. Alternately the same intermediate is prepared by heating the alkenol in the presence of diethylnitromalonate in refluxing mesitylene or decalin, by the method of Shimizu et al . ( Bull . Chem . Soc . Jpn . 1985, 5J3, 2519-2522.) Oxidation of theresuiting alcohol the corresponding aldehyde can be achieved by numerous methods described in the literature (for example see Comprehensive Organic Transformations by Larock, R.C., p 604, 605, 607-613. VCH publishers, New York, New York, 1989) . Reductive amination of the intermediate aldehyde (for suitable methods see, Abdel-Magid, A. F. , Maryanoff, C. A., and Carson, K.G., Tetrahedron Lett . , 1990, 3_1_, 5595-5598, and references contained therein ) with a variety of heteroaryl amines, which may additionally contain suitable protecting groups, provides the substituted amines. Alternatively, depending on the nature of the heterocyclic amine, the reductive amination can be carried out in a two step procedure, wherein initial formation of an i ine is carried out by treatment of the aldehyde with the desired amine in the presence of a dehydrating agent such as magnesium sulf te, sodium sulfate, or molecular sieves, in a suitable solvent such as carbon tetrachloride, methylene chloride, benzene or toluene (for example see, Modern Synthetic Reactions 2nd ed. House, H. 0., Benj min/Cummings Publishing Co, Menlo Park, Ca. , 1972.). The imine is then subsequently reduced with a variety of reducing agents such as sodium borohydride, sodium cyanoborohydride, or sodium triacetoxyborohydride, in a suitable solvent such as methanol, ethanol, tetrahydrofuran, dioxane or 1,2- dichloroethane, to provide the desired amines. Hydrolysis of the ester using conventional methods known to one skilled in the art. of organic synthesis provides acid intermediates. Coupling of the resulting acids to the appropriately substituted α- or β-amino ester is accomplished using standard coupling reagents, as described above. The esters may be saponified or in the case of tert-butyl esters the acid may be produced either by the action of trifluoroacetic acid with or without an inert solvent such as methylene chloride, or by the action of anhydrous HCI in a solvent such as ether or dioxane. Additional protecting groups may be removed by methods known to one skilled in the art ( for example see, Protective Groups in Organic Synthesis 2nd,ed. Greene, T. W., and Wuts, P. G. M'. , John Wiley & Sons, Inc. New York, 1991) . Scheme V: ty A convenient preparation of suitably protected 2 aminoimidazoles is outlined in Scheme Va. Scheme Va : R = trityl or SEM R = trityl or SEM Compounds of formula I wherein b is a double bond can be prepared using one of the routes depicted in Scheme VI. Bromination followed by subsequent dehydrobromination of a suitably substituted methyl 3- (cyanophenyl)isoxazolin-5-ylacetate, prepared as described above, using the method of Elkasaby & Salem (Indian J. Chem., 1980, 19B, 571-575) provides the corresponding isoxazole intermediate. Alternately, this intermediate can be obtained by 1,3-dipolar cycloaddition of a cyanophenylnitrile oxide (prepared from the corresponding chlorooxime as described in Scheme I) with an appropriate alkyne to give the isoxazole directly. Hydrolysis of the ester using conventional methods known to one skilled in the art of organic synthesis provides the acid intermediates. Coupling of the resulting acids to an appropriately substituted a- or /--amino ester is accomplished using standard coupling reagents, as described above. Saponification gives the acids. Scheme VI A Compounds of Formula I wherein b is a double bond and Q is oxygen can be prepared from commercially available methyl 3-hydroxy-5-isoxazolecarboxylate as illustrated in Scheme VII. Coupling of the hydroxy group to a suitably N-protected amino alcohol can be achieved in one step under Mitsunobu reaction conditions (Hughs, D.L.; Organic Reactions, Volume 42, John Wiley and Sons, 1992, pages 335-656) . Alternately, a two step process of activation of the N-protected aminoalcohol as a aryl or alkyl sulfonate ester or by conversion to halide followed by alkylation of the hydroxyisoxazole gives the same result. Bases suitable for this reaction include alkaline hydrogen carbonates, alkaline carbonates, cesium carbonate, alkaline hydrides, and alkaline alcoholates such as sodium ethoxide and potassium t- butoxide. The reaction can be run in a number of different solvents including lower alkyl and branched alcohols, ethereal solvents, or halocarbons, but it proceeds most readily in polar aprotic solvents such as DMF and DMSO. Saponification of the ester using standard conditions known to one skilled in the art provides an acid intermediate which can be converted using the methods described above into compounds of Formula I. Scheme VII N -n co 2 *Mβ Additional aldehydes useful for the preparation of compounds of formula I in the methods depicted in schemes I -VII can be prepared as illustrated in Scheme VIII below: Scheme VIII lit prep.

Chem. 1994, 13:715-736 TrHN TrHN Heterocyclic alkenes and aldehydes useful as intermediates for the preparation of compounds of formula I in the methods depicted in Schemes I-VII can be prepared as illustrated in Scheme Villa and Vlllb. The carboxylic acids prepared in scheme III, can be converted to an acid halide, by a variety of methods, such as treatment with oxalyl chloride or thionyl chloride either neat or in the presence of a suitable solvent such as methylene chloride or toluene, as outlined in the literature ( for example, see Comprehensive Organic Transformations by Larock, R.C., p 964-965. VCH publishers, New York, New York, 1989) . Treatment of the acid chloride with diazomethane in a suitable solvent such as ether, or dioxane, to form the diazoketone, followed by treatment with HBr ( for example, see Comprehensive Organic Transformations by Larock, R.C., p 346. VCH publishers, New York, New York, 1989 ) , provides versatile intermediates for the synthesis of many heterocycles. The examples shown in scheme Villa, are for illustration purposes and do not constitute a limitation on the scope of the invention. For example, as illustrated in method A, the α- haloketone can be treated with N-acetylguanidine in a suitable solvent such as acetonitrile from room temperature to reflux, or N,N-dimethylformamide from room temperature to 80°C according to the method of Little, T. L., and Webber, S. E. ( J. Org. Chem. , 1994, 59, 729S-7305.) to provide a 2-amino-4-imidazole derivative. Alternatively, treatment of the cc-haloketone with thiourea, in the presence of a suitable solvent such as toluene or acetone, at a temperature from 20°C to the boiling point of the solvent, according to the method of Patt, W. C, Skeean, R. w., and Steinbaugh, B. A., ( Synth. Comm. 1990, 2_0, 3097-3102 ) , provides the analogous 2-amino-5-thiazole derivative. The alkenes can be converted by a hydroboration-oxidation procedure ( for example, see Comprehensive Organic Transformations by Larock, R.C., p 497-498. VCH publishers, New York, New York, 1989 ) , to provide the alcohols. he alcohols can be oxidized to the corresponding aldehydes by numerous published methods (for example see Comprehensive Organic Transforma ions by Larock, R.C., p 604, 605, 607-613. VCH publishers, New York, New York, 1989) . Scheme Villa Oxalyl chloride CH 2 N 2 A. N-acetylguanidine Synthesis of pyridyl-containing alkenes and aldehydes, proceeds as depicted in Scheme VIIlb.The amino group of 2-amino-6-methylpyridine is protected by treatment with 2, 6-hexanedione, followed by deprotonation of the methyl group with lithium diisopropylamide according to the method of Breukelman, S. P., Meakins, G. D., and Tirel, M. D. ( J. Chem. Soc. Chem. Comm. 1982, 800-801.) . The lithio intermediate can be trapped with a variety of electrophiles such as formaldehyde, ethylene oxide or 3- (tertbutyldimethylsilyloxy) -1-bromopropane to provide the alcohol intermediates. Oxidation of the alcohol to an aldehyde as described as described in detail above, followed by olefination reaction under any of a number of known conditions, such as, for example, a Wittig reaction or treatment with various titanium reagents provides the alkene intermediates (see Comprehensive Organic Transformations by Larock, R.C., p 173-184. VCH publishers, New York, New York, 1989) . Scheme VI lib oxidation olefination Alternately, reductive amination of the appropriate aldehyde intermediates with heterocyclic amines as shown in method A and method B of Scheme Vlllc, using methods described above, yields the desired amine intermediates. Hydroboration-oxidation of the double bond, followed by oxidation of the alcohol (vide supra) provides additional aldehyde intermediates useful for the synthesis of compounds of this invention. For heterocyclic amines unstable to the hydrogen peroxide required in the hydroboration oxidation procedure, the reductive amination can be carried out on appropriate esterified ω-hydroxy aldehydes, as outlined in method B. Hydrolysis of the esters and oxidation of the alcohol provides the aldehyde.

Selective removal of the Cbz group may be accomplished by hydrogenation using palladium suspended on barium sulfate as the catalyst in a suitable solvent such as methanol or ethanol, with or without a co-solvent, by the method of Nikam, S. S., Kornberg, B.E. , Johnson, D.R., and Doherty, A, M. ( Tetrahedron Lett . 1995, 36, 197-200) . Using this method, the Cbz group can be removed with minimal to no cleavage of the N-0 bond contained in the isozazoline rings shown in Scheme X example A, and Scheme X example B. The resulting amines can be converted to additional compound of formula I by treatment with a wide variety of reagents, for example, acyl halides, chloroformates, isocyanates, sulfonylchlorides, chlorosulfonamides, and sulfonylisocyanates, etc. using standard methods.

Utility The compounds of Formula I of the present invention possess activity as antagonists of integrins such as, for example, the α v β 3 or vitronectin receptor, α v β 5 or α 5 βl 7 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 α v β 3 receptor. The compounds of the present invention possess selectivity for the α v β 3 receptor relative to the GPIIb/IIIa receptor as demonstrated by their lack of 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 I 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 I have the ability to suppress/inhibit angiogenesis in vivo, for example, as demonstrated using animal models of ocular neovasculari∑iation. 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 "μg" denotes microgram, "mg" denotes milligram, "g" denotes gram, "μL" denotes microliter, "mL" denotes milliliter, "L" denotes liter, "nM" denotes nanomolar, "μM" 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 α v β 3 (human placenta) - Vitronectin ELISA, α v β 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 5 o or K_ value of lese than about 10 μM for the inhibition of α v β 3 -Vitronectin Binding Assay, with compounds preferably having Ki values of less than about 0.1 μM. Tested compounds of the present invention are active in the α v β 3 -Vitronectin Binding Assay. Purified ccy (human placenta) - Vitronectin ELISA The α v β 3 receptor was isolated from human placental extracts prepared using octylglucoside. The extracts were passed over an affinity column composed of anti-α v β 3 monoclonal antibody (LM609) 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 gave two bands on SDS gel which were confirmed as α v β 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 oc v β 3 with no detectable levels of α v βs according to the gel (c ) and according to effects of blocking antibodies for the α v 3 or α v βs in the ELISA. A submaximal concentration of biotinylated vitronectin was selected based on cone, response curve with fixed receptor cone, and variable concentrations of biotinylated vitronectin. ocv < -Vitronectin Binding Assay The purified receptor is diluted with coating buffer (20 mM Tris HCI, 150 mM NaCl, 2.0 mM CaCl 2 , 1.0 mM MgCl 2 -6H 2 0, 1.0 mM MnCl -4H 2 0) and coated (100 μL/well) on Costar (3590) high capacity binding plates overnight at 4°C. The coating solution is discarded and the plates washed once with blocking/binding buffer (B/B buffer, 50 mM Tris HCI, 100 mM NaCl, 2.0 mM CaCl 2 1.0 mM MgCl 2 - 6H 2 0,1.0 mM MnCl 2 -4H_0) . Receptor is then blocked (200 μL/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 μL) and either inhibitor (11 μL) or B/B buffer w/l.0% BSA (11 μL) 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 μL/well) in B/B buffer containing 1.0% BSA. The plates are washed twice with B/B buffer and alkaline phosphatase substrate (100 μL) is added. Color is developed at room temperature. Color development is stopped by addition of 2N NaOH (25 μL/well) and absorbance is read at 405 nm. The IC 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° C. The following day, the cells were harvested, washed and loaded with a fluorescent dye. 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 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 α v β 3 , ctvβs and otsβi 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 x 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 x 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 μL of PRP (5xl0 8 platelets/mL) were added to each micro test tube, and transmittance was set to 0%. 20 μL of ADP (10 μM) was added to each tube, and the aggregation profiles were plotted (% transmittance versus time) . Test agent (20 μL) was added at different concentrations prior to the addition of the platelet agonist. Results are expressed as % inhibition of agonist-induced platelet aggregation.

Ophthal . & Visual Science (1994) 35: 101-111. 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 α v β 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 cyclic 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 parenterally, 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 compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using those forms of transdermal skin patches wall known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittant throughout the dosage regimen. The active ingredient can be administered intranasally to a mammal at a dosage range of about 0.01 to 0.5 mg/kg while the preferred dosage range is about 0.01-0.1 mg/kg. Compositions of the active ingredients can be administered intranasally by preparing a suitable formulation of the active ingredient by procedures well known to those skilled in the art. Preferably the formulations are prepared with suitable nontoxic pharmaceutically acceptable ingredients. These ingredients are known to those skilled in the preparation of nasal dosage forms and some of these can be found in REMINGTON'S PHARMACEUTICAL SCIENCES. 17th edition, 1985 a standard reference in the field. The choice of suitable carriers is highly dependent upon the exact nature of the nasal dosage form desired, e.g., solutions, suspensions, ointments, or gels. Nasal dosage forms generally contain large amounts of water in addition to the active ingredient. Minor amounts of other ingredients such as pH adjusters, emulsifiers or dispersing agents, preservatives, surfactants, jelling agents, or buffering and other stabilizing and solubilizing agents may also be present. Preferably, the nasal dosage form should be isotonic with nasal secretions. An example of a nasal solution composition of this invention includes: In this example the active drug can be in one vial and the rest of the formulation can be in another vial. The drug can be reconstituted when needed. The formulation of this invention may be varied to include: (1) other acids and bases to adjust the pH; (2) other tonicity imparting agents such as glycerin and dextrose; (3) other antimicrobial preservatives such as other parahydroxy benzoic acid esters, sorbate, benzoate, propionate, chlorbutanol, phenylethyl alcohol, and mercurials; (4) other viscosity imparting agents such as sodium carboxy-methylcellulose microcrystalline cellulose, polyvinyl-pyrrolidone, polyvinyl alcohol and other gums; (5) suitable absorption enhancers; (6) stabilizing agents such as antioxidants, like bisulfite and ascorbate, metal chelating agents such as sodium edetate and drug solubility enhancers such as polyethylene glycols. The above formulation can be administered as drops, sprays, aerosols or by any other intranasal dosage form. Optionally, the delivery system can be a unit dose delivery system. The volume of solution or suspension delivered per dose can be anywhere from 5 to 400 μL, and preferably between 50 and 150 μL. Delivery systems for these various dosage forms can be dropper bottles, plastic squeeze units, atomizers, nebulizers or pharmaceutical aerosols in either unit dose or multiple dose packages. The combination products of this invention, such as the novel α v β 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 α v β 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 α v β 3 antagonist compounds of this invention and the anti-coagulant agent, anti-platelet agent, thrombin inhibi-tor, 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 UNIVIAL™ 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.
