A novel coronavirus outbreak has posed a severe threat to human healthcare globally, and researchers have been searching for ways to control and prevent this deadly disease. In this study, antiviral compounds from traditional Indian medicinal plants were screened, and amentoflavone was identified as a potential inhibitor of the SARS-CoV2 main protease. Further biochemical experiments are needed to understand the mechanism of inhibition by these plant-derived antiviral compounds.
A novel coronavirus (SARS-CoV2) has caused a major outbreak in humans around the globe, and it became a severe threat to human healthcare than all other infectious diseases. Researchers were urged to discover and test various approaches to control and prevent such a deadly disease. Considering the emergency and necessity, we screened reported antiviral compounds present in the traditional Indian medicinal plants for the inhibition of SARS-CoV2 main protease. In this study, we used molecular docking to screen 41 reported antiviral compounds that exist in Indian medicinal plants and shown amentoflavone from the plantTorreyanuciferawith a higher docking score. Furthermore, we performed a 40 ns atomic molecular dynamics simulation and free binding energy calculations to explore the stability of the top five protein-ligand complexes. Through the article, we insist that the amentoflavone, hypericin and Torvoside H from the traditional Indian medicinal plants may be used as a potential inhibitor of SARS-CoV2 main protease and further biochemical experiments could shed light on understanding the mechanism of inhibition by these plant-derived antiviral compounds.
