Discovery of BMS-961955, an allosteric inhibitor of the hepatitis C virus NS5B polymerase

Bioorg Med Chem Lett. 2017 Aug 1;27(15):3294-3300. doi: 10.1016/j.bmcl.2017.06.024. Epub 2017 Jun 11.

Abstract

The synthesis, structure-activity relationship (SAR) data, and further optimization of the metabolic stability and pharmacokinetic (PK) properties for a previously disclosed class of cyclopropyl-fused indolobenzazepine HCV NS5B polymerase inhibitors are described. These efforts led to the discovery of BMS-961955 as a viable contingency backup to beclabuvir which was recently approved in Japan for the treatment of HCV as part of a three drug, single pill combination marketed as XimencyTM.

Keywords: Antiviral agent; Cyclopropyl-fused indolobenzazepine; Direct-acting antiviral agent; HCV NS5B; Metabolic stability; Polymerase.
