Abstract

A novel series of hepatitis C virus (HCV) NS3/4A Protease Inhibitors bearing a P2-P4 macrocycle and a P1-P1' alpha-ketoamide serine trap is reported. The NS3 protease, which is essential for viral replication, is considered one of the most attractive targets for developing novel anti-HCV therapies. The optimization of both the macrocycle and the warhead portions led to the discovery of compounds 8b and 8 g with a good activity both in the Enzyme as well as in the cell based (replicon) assays with favorable PK profile in a preclinical species.
