Title:

Design and synthesis of lactam-thiophene carboxylic acids as potent hepatitis C virus polymerase inhibitors.

Journal:

Bioorg Med Chem Lett. 2014 Aug 15;24(16):3979-85. doi:, 10.1016/j.bmcl.2014.06.031. Epub 2014 Jun 20.

Abstract:

Herein we report the successful incorporation of a lactam as an amide replacement in the design of hepatitis C virus NS5B Site II thiophene carboxylic acid inhibitors. Optimizing potency in a replicon assay and minimizing potential risk for CYP3A4 induction led to the discovery of inhibitor 22a. This lead compound has a favorable pharmacokinetic profile in rats and dogs.
