Abstract: Hepatitis C virus (HCV) infection is a global health threat and current therapies warrant the need for novel HCV therapies. Several synthetic analogs targeting HCV serine protease and RNA-dependent RNA polymerase have entered clinical development. To investigate the novel HCV NS5B RdRp polymerase inhibitor, screening of a designed data set consisting of benzimidazole analogs by the FlexX docking approach was performed. Binding interactions at the active sites (PDB ID: 2DXS) were evaluated leading to the rationalization of further synthesis and evaluation procedures.

Keywords: virtual screening – anti-HCV – NS5B polymerase – FlexX docking
