ABSTRACT
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the causative agent of the COVID-19 pandemic. Currently, there are no particular antivirals available to battle with COVID-19. The RNA-dependent RNA polymerase (RdRp) has emerged as a novel drug target due to its essential role in virus replication. In this study, turmeric-derived compounds were chosen and subjected to in-silico analysis to evaluate their binding affinity against the RdRp-RNA complex of SARS-CoV-2. Our in-silico approach included the analysis of protein-ligand interactions by molecular docking and molecular dynamics simulations, followed by free energy calculations by molecular mechanics Poisson-Boltzmann surface area analysis. Curcumin and diacetylcurcumin showed stability and good binding affinity at the active site of the SARS-CoV-2 RdRp-RNA complex. Furthermore, to validate the potency of selected compounds, we compared them with Favipiravir and Remdesivir antiviral drugs from our previous analysis on targeting tea bioactive molecules to inhibit RdRp-RNA complex. The comparative analysis revealed that the selected compounds showed higher potential to be developed as RdRp-RNA inhibitors than antiviral medicines Remdesivir and Favipiravir. However, these compounds need to be further validated by in-vitro and in-vivo investigations.
