  • Patent number: 6172057
    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-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. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-&agr; converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection.

  • Patent number: 4645852
    Abstract: In an improved process of converting a 1,2-epoxy-2-phenylbutane or a 1,2-epoxy-2-phenylpentane to a 2-hydroxy-2-phenylbutylsulfonate, sulfamate, or halide, or the corresponding 2-hydroxy-2-phenylpentyl compound, respectively, by the reaction at about 40.degree. to 120.degree. C. in the presence of an organic solvent of the requisite epoxybutane or epoxypentane with a proton source and a nucleophile. The proton source can be a free strong acid such as a sulfonic, sulfamic acid, or hydrohalide acid, or the proton source can be derived from an equilibrium system comprising a free strong acid and weak base in equilibrium with the respective deprotonated strong acid and protonated weak base. The process is carried out in one step with reduction or avoidance of aldehyde formation by rearrangement of the epoxyalkane.
