title: Peptidic inhibitors of the hepatitis C virus serine protease within non-structural protein 3.
abstract: New treatments for HCV (Hepatitis C virus) infections are likely to arise from inhibition of the essential, virally-encoded enzymes. These targets include the serine protease required for processing of the HCV polyprotein. The protease constitutes one functional domain of the bifunctional HCV NS3 (non-structural protein 3). Here, insights regarding the NS3 structure and recently synthesized NS3 inhibitors are reviewed. Interestingly, many NS3 protease inhibitors have taken advantage of an unusual product inhibition by N-terminal products of cleavage at the polyprotein processing sites.
