Description: COMPOUNDS FOR AND A METHOD OF INHIBITING MATRIX METALLOPROTEINASES FIELD OF THE INVENTION The present invention relates to compounds that inhibit matrix metalloproteinases and to a method of inhibiting matrix metalloproteinases using the compounds. More particularly, the present invention relates to a method of treating diseases in which matrix metalloproteinases are involved such as multiple sclerosis, atherosclerotic plaque rupture, restenosis, aortic aneurism, heart failure, periodontal disease, corneal ulceration, burns, decubital ulcers, chronic ulcers or wounds, cancer metastasis, tumor angiogenesis, arthritis, or other autoimmune or inflammatory diseases dependent upon tissue invasion by leukocytes. BACKGROUND OF THE INVENTION The compounds of the present invention are inhibitors of matrix metalloproteinases, e.g., stromelysin- 1 and gelatinase A (72 kDa gelatinase). Stromelysin- 1 and gelatinase A are members of the matrix metalloproteinases (MMP). Other members include fibro blast collagenase, neutrophil collagenase, gelatinase B (92 kDa gelatinase), stromelysin-2, stromelysin-3, matrilysin, collagenase 3, and the newly discovered membrane-associated matrix metalloproteinases (Sato H., Takino T., Okada Y., Cao J., Shinagawa A., Yamamoto E., and Seiki M., Nature. 1994;370:61-65). Stromelysin- 1 is also known as MMP03 and gelatinase A is known as MMP02. In addition, several other matrix metalloproteinases are known: MMP01 - Fibroblast collagenase; MMP07 - Matrilysin; MMP09 Gelatinase B; and MMP 13 - Collagenase -3. The catalytic zinc in matrix metalloproteinases is typically the focal point for inhibitor design. The modification of substrates by introducing chelating groups has generated potent inhibitors such as peptide hydroxamates and thiol-containing peptides. Peptide hydroxamates and the natural endogenous inhibitors of MMPs (TIMPs) have been used successfully to treat animal models of cancer and inflammation. The ability of the matrix metalloproteinases to degrade various components of connective tissue makes them potential targets for controlling pathological processes. For example, the rupture of atherosclerotic plaques is the most common event initiating coronary thrombosis. Destabilization and degradation of the extracellular matrix surrounding these plaques by MMPs has been proposed as a cause of plaque Assuring. The shoulders and regions of foam cell accumulation in human atherosclerotic plaques show locally increased expression of gelatinase B, stromelysin- 1, and interstitial collagenase. In situ zymography of this tissue revealed increased gelatinolytic and caseinolytic activity (Galla Z.S., Sukhova G.K., Lark M.W., and Libby P., "Increased expression of matrix metalloproteinases and matrix degrading activity in vulnerable regions of human atherosclerotic plaques", J. Clin. Invest.. 1994;94:2494-2503). In addition, high levels of stromelysin RNA message have been found to be localized to individual cells in atherosclerotic plaques removed from heart transplant patients at the time of surgery (Henney A.M., Wakeley P.R., Davies M.J., Foster K., Hembry R., Murphy G., and Humphries S., "Localization of stromelysin gene expression in atherosclerotic plaques by in situ hybridization", Proc. Nat'l. Acad. Sc 1991 ;88:8154-8158). Inhibitors of matrix metalloproteinases will have utility in treating degenerative aortic disease associated with thinning of the medial aortic wall. Increased levels of the proteolytic activities of MMPs have been identified in patients with aortic aneurisms and aortic stenosis (Vine N. and Powell J.T., "Metalloproteinases in degenerative aortic diseases", Clin. Sci.. 1991;81 :233-239). Heart failure arises from a variety of diverse etiologies, but a common characteristic is cardiac dilation which has been identified as an independent risk factor for mortality (Lee T.H., Hamilton M.A., Stevenson L.W., Moriguchi J.D., Fonarow G.C., Child J.S., Laks H., and Walden J.A., "Impact of left ventricular size on the survival in advanced heart failure", Am. J. Cardiol.. 1993;72:672-676). This remodeling of the failing heart appears to involve the breakdown of extracellular matrix. Matrix metalloproteinases are increased in patients with both idiopathic and ischemic heart failure (Reddy H.K., Tyagi S.C, Tjaha I.E., Voelker D.J., Campbell S.E., and Weber K.T., "Activated myocardial collagenase in idiopathic dilated cardiomyopathy", Clin. Res.. 1993;41:660A; Tyagi S.C, Reddy H.K., Voelker D., Tjara I.E., and Weber K.T., "Myocardial collagenase in failing human heart", Clin. Res.. 1993 ;41 :681 A). Animal models of heart failure have shown that the induction of gelatinase is important in cardiac dilation (Armstrong P.W., Moe G.W., Howard R.J., Grima E.A., and Cruz T.F., "Structural remodeling in heart failure: gelatinase induction", Can. J. Cardiol.. 1994;10:214-220), and cardiac dilation precedes profound deficits in cardiac function (Sabbah H.N., Kono T., Stein P.D., Mancini G.B., and Goldstein S., "Left ventricular shape changes during the course of evolving heart failure", Am. J. Phvsiol.. 1992;263:H266-H270). Neointimal proliferation, leading to restenosis, frequently develops after coronary angioplasty. The migration of vascular smooth muscle cells (VSMCs) from the tunica media to the neointima is a key event in the development and progression of many vascular diseases and a highly predictable consequence of mechanical injury to the blood vessel (Bendeck M.P., Zempo N., Clowes A.W., Galardy R.E., and Reidy M., "Smooth muscle cell migration and matrix metalloproteinase expression after arterial injury in the rat", Circulation Research. 1994;75:539-545). Northern blotting and zymographic analyses indicated that gelatinase A was the principal MMP expressed and excreted by these cells. Further, antisera capable of selectively neutralizing gelatinase A activity also inhibited VSMC migration across basement membrane barrier. After injury to the vessel, gelatinase A activity increased more than 20-fold as VSMCs underwent the transition from a quiescent state to a proliferating, motile phenotype (Pauly R.R., Passaniti A., Bilato C, Monticone R., Cheng L., Papadopoulos N., Gluzband Y.A., Smith L., Weinstein C, Lakatta E., and Crow M.T., "Migration of cultured vascular smooth muscle cells through a basement membrane barrier requires type IV collagenase activity and is inhibited by cellular differentiation", Circulation Research. 1994;75:41-54). Collagenase and stromelysin activities have been demonstrated in fibroblasts isolated from inflamed gingiva (Uitto V.J., Applegren R., and Robinson P.J., "Collagenase and neutral metalloproteinase activity in extracts from inflamed human gingiva", J. Periodontal Res.. 1981 ; 16:417-424), and enzyme levels have been correlated to the severity of gum disease (Overall CM., Wiebkin O.W., and Thonard J.C, "Demonstrations of tissue collagenase activity in vivo and its relationship to inflammation severity in human gingiva", J. Periodontal Res., 1987;22:81-88). Proteolytic degradation of extracellular matrix has been observed in comeal ulceration following alkali bums (Brown S.L, Weller C.A., and Wasserman H.E., "Collagenolytic activity of alkali burned corneas", Arch. Opthalmol., 1969;81 :370-373). Thiol-containing peptides inhibit the collagenase isolated from alkali-burned rabbit corneas (Bums F.R., Stack M.S., Gray R.D., and Paterson C.A., Invest. Opththamol.. 1989;30: 1569-1575). Stromelysin is produced by basal keratinocytes in a variety of chronic ulcers (Saarialho-Kere U.K., Ulpu K., Pentland A.P., Birkedal-Hansen H., Parks W.C, Welgus H.G., "Distinct populations of basal keratinocytes express stromelysin- 1 and stromelysin-2 in chronic wounds", J. Clin. Invest.. 1994;94:79-88). Stromelysin- 1 mRNA and protein were detected in basal keratinocytes adjacent to but distal from the wound edge in what probably represents the sites of proliferating epidermis. Stromelysin- 1 may thus prevent the epidermis from healing. Davies, et al., (Cancer Res.. 1993;53:2087-2091) reported that a peptide hydroxamate, BB-94, decreased the tumor burden and prolonged the survival of mice bearing human ovarian carcinoma xenografts. A peptide of the conserved MMP propeptide sequence was a weak inhibitor of gelatinase A and inhibited human tumor cell invasion through a layer of reconstituted basement membrane (Melchiori A., Albili A., Ray J.M., and Stetler-Stevenson W.G., Cancer Res.. 1992;52:2353-2356), and the natural tissue inhibitor of metalloproteinase-2 (TIMP-2) also showed blockage of tumor cell invasion in in vitro models (DeClerck Y.A., Perez N., Shimada H., Boone T.C, Langley K.E., and Taylor S.M., Cancer Res., 1992;52:701-708). Studies of human cancers have shown that gelatinase A is activated on the invasive tumor cell surface (Strongin A.Y., Manner B.L., Grant G.A., and Goldberg G.I., J. Biol. Chem.. 1993;268:14033-14039) and is retained there through interaction with a receptor-like molecule (Monsky W.L., Kelly T., Lin C.-Y., Yeh Y., Stetler-Stevenson W.G., Mueller S.C, and Chen W.-T., Cancer Res.. 1993;53:3159-3164). Inhibitors of MMPs have shown activity in models of tumor angiogenesis (Taraboletti G., Garofalo A., Belotti D., Drudis T., Borsotti P., Scanziani E., Brown P.D., and Giavazzi R., Journal of the National Cancer Institute. 1995;87:293; and Benelli R., Adatia R., Ensoli B., Stetler-Stevenson W.G., Santi L., and Albini A., Oncology Research. 1994;6:251-257). Several investigators have demonstrated consistent elevation of stromelysin and collagenase in synovial fluids from rheumatoid and osteoarthritis patients as compared to controls (Walakovits L.A., Moore V.L., Bhardwaj N., Gallick G.S., and Lark M.W., "Detection of stromelysin and collagenase in synovial fluid from patients with rheumatoid arthritis and post-traumatic knee injury", Arthritis Rheum., 1992;35:35-42; Zafarullah M., Pelletier J.P., Cloutier J.M., and Marcel-Pelletier J., "Elevated metalloproteinases and tissue inhibitor of metalloproteinase mRNA in human osteoarthritic synovia", J. Rheumatol.. 1993;20:693-697). TIMP-1 and TIMP-2 prevented the formation of collagen fragments, but not proteoglycan fragments, from the degradation of both the bovine nasal and pig articular cartilage models for arthritis, while a synthetic peptide hydroxamate could prevent the formation of both fragments (Andrews H.J., Plumpton T.A., Harper G.P., and Cawston T.E., Agents Actions. 1992;37:147-154; Ellis A.J., Curry V.A., Powell E.K., and Cawston T.E., Biochem. Biophvs. Res. Cornmun.. 1994;201:94-101). Gijbels, et al., (J. Clin. Invest.. 1994;94:2177-2182) recently described a peptide hydroxamate, GM6001, that suppressed the development or reversed the clinical expression of experimental allergic encephalomyelitis (EAE) in a dose dependent manner, suggesting the use of MMP inhibitors in the treatment of autoimmune inflammatory disorders such as multiple sclerosis. A recent study by Madri has elucidated the role of gelatinase A in the extravasation of T-cells from the blood stream during inflammation (Ramanic A.M. and Madri J.A., "The Induction of 72-kD Gelatinase in T Cells upon Adhesion to Endothelial Cells is VCAM-1 Dependent", J. Cell Biology. 1994; 125: 1 165-1 178). This transmigration past the endothelial cell layer is coordinated with the induction of gelatinase A and is mediated by binding to the vascular cell adhesion molecule- 1 (VCAM-1). Once the barrier is compromised, edema and inflammation are produced in the CNS. Leukocytic migration across the blood-brain barrier is known to be associated with the inflammatory response in EAE. Inhibition of the metalloproteinase gelatinase A would block the degradation of extracellular matrix by activated T-cells that is necessary for CNS penetration. These studies provided the basis for the belief that an inhibitor of stromelysin- 1 and/or gelatinase A will treat diseases involving disruption of extracellular matrix resulting in inflammation due to lymphocytic infiltration, inappropriate migration of metastatic or activated cells, or loss of structural integrity necessary for organ function. We have identified a series of dibenzofuran sulfonamide compounds that are inhibitors of matrix metalloproteinases, particularly stromelysin- 1 and gelatinase A, and thus useful as agents for the treatment of multiple sclerosis, atherosclerotic plaque rupture, restenosis, aortic aneurism, heart failure, periodontal disease, comeal ulceration, bums, decubital ulcers, chronic ulcers or wounds, cancer metastasis, tumor angiogenesis, arthritis, or other autoimmune or inflammatory diseases dependent upon tissue invasion by leukocytes.

Dosage forms for topical administration of a compound of this invention include ointments, powders, sprays, and inhalants. The active component is admixed under sterile conditions with a physiologically acceptable carrier and any preservatives, buffers, or propellants as may be required. Ophthalmic formulations, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention. The compounds of the present invention can typically be administered to a patient at dosage levels in the range of about 0.1 to about 1,000 mg per day. For a normal human adult having a body weight of about 70 kilograms, a dosage in the range of about 0.01 to about 100 mg per kilogram of body weight per day is preferable. The specific dosage used, however, can vary. For example, the dosage can depended on a numbers of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used.

A "therapeutically effective amount" is an amount of a compound of Formula I or II that when administered to a patient having a disease that can be treated with a compound of Formula I or II ameliorates a symptom of the disease. A therapeutically effective amount of a compound of Formula I or II is readily determined by one skilled in the art by administering a compound of Formula I or II to a patient and observing the results. The following examples illustrate particular embodiments of the invention and are not intended to limit the scope of the specification and claims in any manner. EXAMPLES General Synthetic Schemes The compounds of the present invention can be synthesized using a number of different synthetic routes. Referring to General Scheme 1 the common starting materials are the sulfonyl chlorides (1). These are easily synthesized by anyone skilled in the art by sulfonation of the parent heterocycle. Some representative procedures are as follows. For dibenzofuran (1, X = O) and dibenzothiophene (1, X = S), the parent heterocycle is sulfonated at the 2-position using one equivalent of chlorosulfonic acid in chloroform at 0°C according to the method of Bassin, et al., Phosphoms. Sulfur and Silicon. 1992;72:157-170). The sulfonic acid is then converted to the corresponding sulfonyl chloride (1, X = O,S) by treatment with phosphoms pentachloride at 170-180°C For carbazole (1, X = NH), the parent heterocycle is sulfonated at the 3-position using sulfuric acid at 100°C followed by neutralization with barium carbonate to yield the barium salt of the corresponding sulfonic acid according to the method of Loza, et al., Sb. Mater.Nauch.-Tekh. Konf. Ukrain. Zaoch. Poitekh. Inst. Vith, Kharkov, 1966:202-5). The sulfonic acid is then converted to the corresponding sulfonyl chloride (1, X = NH) by treatment with phosphoms pentachloride at 170-180°C or reaction with either phosphoryl chloride, thionyl chloride, or oxalyl chloride. For fluorene (1, X = CH 2 ), according to the method of Chrzaszczewska, et al., Lodz. Tow. Nauk.. Wydz. 3, Acta Chi ., 1966;1 1 : 143-55, the parent carbocycle is sulfonated at the 2-position using one equivalent of chlorosulfonic acid in chloroform at 0°C followed by neutralization with potassium hydroxide to give the potassium salt of the corresponding sulfonic acid. This fluorene derivative can then be oxidized using aqueous potassium permanganate at 80°C to the corresponding fluorenone derivative (1, X = CO). The sulfonic acid salts are then converted to the sulfonyl chloride (1, X = CH 2 , CO) by treatment with phosphoms pentachloride and phosphoryl chloride in chloroform. In Method A, the sulfonyl chloride (1) is condensed directly with the natural amino acid using a base such as triethylamine (TEA) in a mixture of tetrahydrofuran(THF) and water (3:5) at 10°C to yield the desired compound (2). The corresponding hydroxamic acid (5) can be conveniently prepared by coupling the acid (2) with an O-protected (usually benzyl) hydroxylamine using dicyclohexylcarbodiimide (DCC) as the coupling agent in dichloromethane at temperatures ranging from -(10) to 0°C The protecting group can be removed from compound (4) by catalytic hydrogenolysis using hydrogen gas at 50 psi and Pd/BaSO4 in aqueous methanol to yield the hydroxamic acid derivative (5). In Method B, the sulfonyl chloride (1) is condensed with a suitably C-protected (usually tertiary butyl ester) amino acid using a base such as N-methylmorpholine (NMM) in a solvent such as dichloromethane at 0°C to yield compound (3). The protecting group can be removed from the carboxylic acid by treatment with trifluoroacetic acid in dichloromethane at 25-35°C using anisole as a carbocation scavenger to yield (2). Referring to General Scheme 2, compounds of the present invention (both N-substituted and N-unsubstituted sulfonamides) can also be synthesized by alkylation of the amino nitrogen of a sulfonamide of formula (6) with an amine alkylating agent of formula (7) to yield 9, wherein any substituents which are potentially reactive in the alkylation reaction may themselves be protected from such reaction. Compounds of formula 9 can then be hydrolyzed to the compounds of this present invention by basic hydrolysis using an alkali metal hydroxide such as sodium hydroxide in a solvent mixture such as THF and water. R 1 is typically a carboxylic acid protecting group (such as a methyl or ethyl ester). Leaving groups (Z) are well known in the art and include halogen atoms (such as bromine) and triflate. Sulfonamides of formula (6) may be prepared by standard methods, including the reaction of an amine of formula (8) with the sulfonyl chloride (1).

The resulting solution was stirred at room temperature for 24 hours. The solution was then concentrated in vacua and the residue redissolved in water (10 mL). This solution was cooled in an ice bath and then acidified with IN HC1. An oil was deposited, which was then triturated with ethyl acetate and hexane to give the title product (0.54 g, 35%), Melting point = 130-132°C Following the general procedure of Example 1 , the following compound was obtained. EXAMPLE 2 2 (S)-3-f(Dibenzofuran-2-sulfonylamino)-methyll-5-methyl-hexanoic acid. Melting point = 125-128°C Parallel Array Synthesis of Examples A1-A40 The appropriate carboxylic acid (1.5 equivalents, 0.18 mmol), 70 mg of a morpholino-resin (prepared according to Booth R.J. and Hodges J.C, J. Am. Chem. Soc. 1997;1 19(21):4882-4886) and 1 mL of a 0.18 M solution of isobutylchloroformate in dichloromethane was added to each of 40 different vials. This was shaken for 1 hour and then 1 mL of a 0.12 M stock solution of 6-amino- 2-(dibenzofuran-2-sulfonylamino)-hexanoic acid methyl ester hydrobromide in triethylamine was added to each of the vials. The vials were sealed and shaken for 16 hous at room temperature. An excess of an amino-resin and an isocyanato-resin (also both prepared according to Booth and Hodges, Supra., 1997) was added to each vial and shaken for 16 hours to quench unreacted starting materials. Each reaction was filtered through a plug of glass wool, and the resins were washed with 2 mL tetrahydrofuran. The filtrate was evaporated under a stream of nitrogen, and the residue in each vial was redissolved in 1 mL dioxane. One milliliter of a 0.6 M aqueous solution of lithium hydroxide was added, and the resulting mixtures were shaken for 16 hours. Each reaction was washed with diethyl ether and the aqueous layer was then acidified with 1 molar hydrochloric acid.

TABLE 1 MMP Inhibitor Bioassay: Animals are dosed by gavage with either vehicle or compound at 2, 10, or 50 mg/kg. Blood samples are collected from 3-4 animals from each dosing group at 1 , 2, 4, 6, and 24 hour postdose, centrifuged, and the plasma immediately frozen at -20°C Plasma protein is precipitated with an equal volume of acetonitrile and separated by centrifugation at room temperature. The supemate is evaporated to dryness and reconstituted to the original plasma volume with 50 mM Tris, pH 7.6. Ten-fold serial dilutions of the reconstituted plasma samples are prepared in 50 mM Tris, pH 7.6 for dose response assays using the appropriate thiopeptolide assay. The concentration of plasma which yields 50% inhibition of enzyme is determined and used to calculate the inhibitor plasma level from the known IC50 value. To demonstrate that the compound can be quantitatively extracted from plasma as active inhibitor, controls for each inhibitor include normal rat plasma, normal rat plasma spiked with compound, and buffer dilutions of compound. All control samples are subjected to acetonitrile precipitation and analyzed with the thiopeptolide assay. Bioassay of Example 1: At a dose of 50 mg/kg peak plasma levels of 71 μM were achieved at 1 to 4 hours. At 24 hours postdose, plasma levels of 29 μM were achieved.
