Depeptidization efforts on P3-P′2 α-ketoamide inhibitors of HCV NS3-4A serine protease: Effect on HCV replicon activity

Depeptidization efforts of the P3-P2 region of P 3 capped α-ketoamide inhibitor of HCV NS3 serine protease 1 are reported. We clearly established that N-methylation of the P2 nitrogen and modification of the P2′
