Patent number: 6172057Abstract: 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-inflammatory 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.

Patent number: 6121300Abstract: The present invention relates to compositions and methods for reversing advanced glycosylation end product-mediated cross-linking and protein aging. Accordingly, compositions are described which comprise thiazolium compounds substituted with heterocyclic groups which are capable of reversing the formation of advanced glycosylation end product cross-links. Both industrial and therapeutic applications for the invention are disclosed, as food spoilage and animal protein aging can be treated. Such compounds have particular application in the treatment of protein aging such as is responsible for the complications of aging and diabetes.Type: GrantFiled: November 10, 1998Date of Patent: September 19, 2000Inventors: Dilip R. Wagle, Sheng-Ding Fang, Taikyun Rho, John J. Egan, Sara Vasan, Peter Ulrich, Anthony Cerami
