摘要:
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.

摘要:
The present invention provides ribonucleoside 2′,3′-cyclic acetals of structural formula I which are precursors or prodrugs of inhibitors of RNA-dependent RNA viral polymerase. These compounds are precursors of inhibitors of RNA-dependent RNA viral replication and are useful for the treatment of RNA-dependent RNA viral infection. They are particularly useful as precursors or prodrugs of inhibitors of hepatitis C virus (HCV) NS5B polymerase, as precursors or prodrugs of inhibitors of HCV replication, and/or for the treatment of hepatitis C infection. The invention also describes pharmaceutical compositions containing such ribonucleoside 2′,3′-cyclic acetals alone or in combination with other agents active against RNA-dependent RNA viral infection, in particular HCV infection. Also disclosed are methods of inhibiting RNA-dependent RNA polymerase, inhibiting RNA-dependent RNA viral replication, and/or treating RNA-dependent RNA viral infection with the ribonucleoside 2′,3′-cyclic acetals of the present invention.
