ABSTRACT:

TECHNICAL FIELD
This invention is directed to compounds that are useful in treating diseases associated with metalloprotease activity, particularly zinc metalloprotease activity. The invention is also directed to pharmaceutical compositions comprising the compounds, and to methods of treating metalloprotease-related maladies using the compounds or the pharmaceutical compositions.
BACKGROUND
A number of structurally related metalloproteases effect the breakdown of structural proteins. These metalloproteases often act on the intercellular matrix, and thus are involved in tissue breakdown and remodeling. Such proteins are referred to as metalloproteases or MPs.
There are several different families of MPs, classified by sequence homology, disclosed in the art. These MPs include Matrix-Metallo Proteases (MMPs); zinc metalloproteases; many of the membrane bound metalloproteases; TNF converting enzymes; angiotensin-converting enzymes (ACEs); disintegrins, including ADAMs (See Wolfsberg et al, 131
J. Cell Bio
. 275-78 October, 1995); and the enkephalinases. Examples of MPs include human skin fibroblast collagenase, human skin fibroblast gelatinase, human sputum collagenase, aggrecanse and gelatinase, and human stromelysin. Collagenases, stromelysin, aggrecanase and related enzymes are thought to be important in mediating the symptomatology of a number of diseases.
Potential therapeutic indications of MP inhibitors have been discussed in the literature. See, for example, U.S. Pat. No. 5,506,242 (Ciba Geigy Corp.) and U.S. Pat.

For example, ulcerative conditions can result in the cornea as the result of alkali burns or as a result of infection by Pseudomonas aeruginosa, Acanthamoeba, Herpes simplex and vaccinia viruses. Other examples of conditions characterized by undesired metalloprotease activity include periodontal disease, epidermolysis bullosa, fever, inflammation and scleritis (e.g., DeCicco et al., World Patent Publication WO 95/29892 published Nov. 9, 1995).
In view of the involvement of such metalloproteases in a number of disease conditions, attempts have been made to prepare inhibitors to these enzymes. A number of such inhibitors are disclosed in the literature. Examples include U.S. Pat. No. 5,183,900, issued Feb. 2, 1993 to Galardy; U.S. Pat. No. 4,996,358, issued Feb. 26, 1991 to Handa, et al.; U.S. Pat. No. 4,771,038, issued Sep. 13, 1988 to Wolanin, et al.; U.S. Pat. No. 4,743,587, issued May 10, 1988 to Dickens, et al., European Patent Publication No. 575,844, published Dec. 29, 1993 by Broadhurst, et al.; International Patent Publication No. WO 93/09090, published May 13, 1993 by Isomura, et al.; World Patent Publication 92/17460, published Oct. 15, 1992 by Markwell et al.; and European Patent Publication No. 498,665, published Aug. 12, 1992 by Beckett, et al.
It would be advantageous to inhibit these metalloproteases in treating diseases related to unwanted metalloprotease activity. Though a variety of MP inhibitors have been prepared, there is a continuing need for potent matrix metalloprotease inhibitors useful in treating diseases associated with metalloprotease activity.
