| | Acetylenic aryl sulfonamide and phosphinic acid amide hydroxamic acid TACE inhibitors - US Patent 6762178 (Site not responding. Last check: 2007-11-05) |
 | | The compounds of this invention are shown to inhibit the enzymes MMP-1, MMP-9, MMP-13 and TNF-α converting enzyme (TACE) and are therefore useful in the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, graft rejection, insulin resistance, bone disease and HIV infection. |
 | | The hydroxamic acid compounds of the invention, 1, are prepared according to Scheme 1 by converting a carboxylic acid, 2, into the corresponding acid chloride or anhydride, or by reacting it with a suitable peptide coupling reagent, followed by reaction with hydroxylamine to give 1, or with a protected hydroxylamine derivative to give 3. |
 | | The compounds of this invention may also be administered transdermally through the use of a transdermal patch containing the active compound and a carrier that is inert to the active compound, is non-toxic to the skin, and allows delivery of the agent for systemic absorption into the blood stream via the skin. |
