title: Alpha-ketoamides, alpha-ketoesters and alpha-diketones as HCV NS3 protease inhibitors.
abstract: Peptide-based alpha-ketoamides, alpha-ketoesters and alpha-diketones were designed, synthesized and evaluated against HCV NS3 protease. Alpha-ketoamides have the highest affinity among the three classes, with 8 being the most potent inhibitor with an IC50 of 340 nM.
