ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to novel biphenyl butyric acid compounds and their derivatives useful as pharmaceutical agents, to methods for their production, to pharmaceutical compositions which include these compounds and a pharmaceutically acceptable carrier, and to pharmaceutical methods of treatment. The novel compounds of the present invention are inhibitors of matrix metalloproteinases, e.g., gelatinase A (72 kDa gelatinase) and stromelysin-1. More particularly, the novel compounds of the present invention are useful in the treatment of atherosclerotic plaque rupture, aortic aneurism, heart failure, restenosis, periodontal disease, corneal ulceration, treatment of burns, decubital ulcers, wound repair, cancer, inflammation, pain, arthritis, multiple sclerosis, and other autoimmune or inflammatory disorders dependent on the tissue invasion of leukocytes or other activated migrating cells. Additionally, the compounds of the present invention are useful in the treatment of acute and chronic neurodegenerative disorders including stroke, head trauma, spinal cord injury, Alzheimer's disease, amyotrophic lateral sclerosis, cerabral amyloid anigopathy, AIDS, Parkinson's disease, Huntington's disease, prion diseases, myasthenia gravis, and Duchenne's muscular dystrophy.
Gelatinase A and stromelysin-1 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, collagebase 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 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 a focal point for inhibitor design. The modification of substrates by introducing chelating groups has generated potent inhibitors such as peptide hydroxymates 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 an atherosclerotic plaque in the most common event initiating coronary thrombosis. Destablization 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 (Galis 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 proteloytic activities of MMPs have been identified in patients with aortic aneurisms and aoritic stenosis (Vine N. and Powell J. T., “Metalloproteinases in degenerative aortic diseases”,
Clin. Sci.,
1991;81:233-239).
Heart failure arises from a number 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;41:681A). 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. Physiol.,
1992;263:H266-270).
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 (Utto V. J., Applegreen 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 C. M., 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 corneal ulceration following alkali burns (Brown S. I., Weller C. A., and Wasserman H. E., “Collagenolytic activity of alkali burned corneas”,
Arch. Ophthalmol.,
1969;81:370-373). Thiol-containing peptides inhibit the collagenase isolated from alkali-burned rabbit corneas (Burns F. R., Stack M. S., Gray R. D., and Paterson C. A.,
Invest. Ophthalmol.,
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. O., and Welgus H. G., “Distinct
