DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The present invention relates to sulfonamide compounds that inhibit matrix metalloproteinases, pharmaceutical compositions that include these compounds, and pharmaceutical methods of treatment using these compounds.


BACKGROUND OF THE INVENTION

The novel compounds of the present invention are inhibitors of matrix metalloproteinases, e.g., stromelysin-1 and gelatinase A (72 kDa gelatinase). More particularly, the compounds of the present invention are useful in the treatment of atherosclerotic plaque rupture, aortic aneurism, heart failure, restenosis, periodontal disease, corneal ulceration, burns, decubital ulcers, chronic ulcers or wounds, cancer metastasis, tumor angiogenesis, arthritis, multiple sclerosis, and other autoimmune or inflammatory disorders dependent on the tissue invasion of leukocytes or other activated migrating cells.
Stromelysin-1 and gelatinase A are members of the matrix metalloproteinase (MMP) family (Woessner J. F., FASEB J. 1991;5:2145-2154). Other members include fibroblast collagenase, neutrophil collagenase, gelatinase B (92 kDa gelatinase), stromelysin-2, stromelysin-3, matrilysin, collagenase 3 (Freije J. M., Diez-Itza I., Balbin M., Sanchez L. M., Blasco R., Tolivia J., and Lopez-Otin C., J. Biol. Chem., 1994;269:16766-16773), 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).
The catalytic zinc in matrix metalloproteinases is 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 fissuring. 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. Sci., 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 in
