  Hepatitis C Virus NS5A Replication Complex Inhibitors. Part 6: Discovery of a Novel and Highly Potent Biarylimidazole Chemotype with Inhibitory Activity Toward Genotypes 1a and 1b Replicons

  摘要：

  A medicinal chemistry campaign that was conducted to address a potential genotoric liability associated with an aniline-derived scaffold in a series of HCV NS5A inhibitors with dual GT-1a/-1b inhibitory activity is described. Anilides 3b and 3c were used as vehicles to explore structural modifications that retained antiviral potency while removing the potential for metabolism-based unmasking of the embedded aniline. This effort resulted in the discovery of a highly potent biarylimidazole chemotype that established a potency benchmark in replicon assays, particularly toward HCV GT-1a, a strain with significant clinical importance. Securing potent GT-1a activity in a chemotype class lacking overt structural liabilities was a critical Milestone in the effort to realize the full clinical potential of targeting the HCV NS5A protein.
