We report a new series of inhibitors for hepatitis C virus NS5B RNA polymerase containing a constrained pentacyclic scaffold. Our SAR studies led to the identification of hexahydroindolo[2,1-a]pyrrolo[3,2-d][2]benzazepines exposing basic groups. The compounds displayed a high activity in the enzyme assay and displayed good activity in the cell-based (replicon) assay in the presence of serum proteins.

The present paper describes a novel series of HCV RNA polymerase inhibitors based on a pyrazolo[1,5-a]pyrimidine scaffold bearing hydrophobic groups and an acidic functionality. Several compounds were optimized to low nanomolar potencies in a biochemical RdRp assay. SAR trends clearly reveal a stringent preference for a cyclohexyl group as one of the hydrophobes, and improved activities for carboxylic acid derivatives.
