Patent number: 5420010Abstract: N-substituted azetidinones are a class of inhibitors of human leukocytes elastase which are known to be useful in the treatment of a wide variety of antiinflammatory and antidegenerative diseases. In inhibiting elastase, the therapeutic agents are shown to form a characteristic stable complex with the enzyme. In the assay disclosed herein, the inhibitor-enzyme complex is advantageously hydrolyzed and specific product(s) of the hydrolysis are measured. The assays are useful in a clinical setting, for determining appropriate dosage and assessing the effectiveness of treatment.Type: GrantFiled: July 30, 1993Date of Patent: May 30, 1995Assignee: Merck & Co., Inc.Inventors: Paul E. Finke, William K. Hagmann, William A. Hanlon, John L. Humes, Wilson B. Knight, Malcolm MacCoss, Richard A. Mumford, Shrenik K. Shah
