Indole 5-carboxamide Thumb Pocket I inhibitors of HCV NS5B polymerase with nanomolar potency in cell-based subgenomic replicons (part 2): Central amino acid linker and right-hand-side SAR studies

In this part 2, new indole 5-carboxamide Thumb Pocket 1 inhibitors of HCV NS5B polymerase are described. Structure–activity relationships (SAR) were explored at the central amino acid linker position and the right-hand-side of the molecule in an attempt to identify molecules with a balanced overall profile of potency (EC50 <100 nM), physicochemical properties and ADME characteristics.
