Abstract
SAR at the C-2 position of benzimidazole-based Thumb Pocket I inhibitors of HCV NS5B polymerase revealed parallel activity for distinct sub-series that harbor 5-hydroxytryptophan amides, neutral thiazole isosteres or recently disclosed cinnamic acid diamides. The consistent SAR among the three sub-series suggest a common binding mode to the Thumb Pocket I allosteric site. New inhibitors with sub-micromolar cell-based replicon potency and improved ‘drug-like’ features are disclosed along with preliminary characterization of their ADME-PK profile.
