  • Thiadiazole amide MMP inhibitors
    Patent number: 5830869
    Abstract: The present invention provides novel thiadiazole amide derivatives represented by formula I ##STR1## The compounds of the present invention inhibit various enzymes from the matrix metalloproteinase family, predominantly stromelysins, and hence are useful for the treatment of matrix metallo endoproteinase diseases such as osteoarthritis, rheumatoid arthritis, septic arthritis, osteopenias such as osteoporosis, tumor metastasis, periodontitis, gingivitis, corneal ulceration, dermal ulceration, gastric ulceration, inflammation and other diseases related to connective tissue degradation.
