This study investigates the polymerase activity of chikungunya virus non-structural protein 4 (nsp4) using molecular modeling and docking studies. A homology model was developed for nsp4 and docked with known RNA-dependent RNA polymerase inhibitors, resulting in the identification of five top-scoring ligands. The research aims to contribute to the development of antiviral compounds targeting nsp4.

Graphical Abstract
Chikungunya viral RNA-dependent RNA polymerase (RdRp) activity is conferred by non
structural protein 4 (nsp4), an important protein target towards the development of antiviral
compounds. The present study deals about the development of homology model of nsP4
followed by molecular docking with known RdRp inhibitors experimented in Hepatitis C virus
(HCV), HIV-1, Paramyxovirus, etc. The predicted catalytic site and two allosteric binding sites
were docked with nucleosidic and non-nucleosidic inhibitors. The best top five scoring ligands
were selected based upon the interaction profiles and a common pharmacophore was developed.
