  • Publication number: 20020032186
    Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-&agr; converting enzyme (TACE), a pro-inflmatory cytokine, catalyzes the formation of TNF-&agr; from membrane bound TNF-&agr; precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states.
