title: Azapeptides as inhibitors of the hepatitis C virus NS3 serine protease.
abstract: Truncation and substitution SAR studies of azapeptide-based inhibitors of the Hepatitis C virus (HCV) NS3 serine protease have been performed. These azapeptides were designed from the HCV polyprotein's NS5A-NS5B trans cleavage junction and contained an azaamino acid residue at the P1 position. These azapeptides exhibited predominantly non-acylating, competitive inhibition, contrary to classical azapeptides.
