The unavailability of a proper drug against SARS-CoV-2 infections and the emergence of various variants created a global crisis. In the present work, we have studied the antiviral behavior of feverfew plant in treating COVID-19. We have reported a systematic in silico study with the antiviral effects of various phytoconstituents Borneol (C10H18O), Camphene (C10H16), Camphor (C10H16O), Alpha-thujene (C10H16), Eugenol (C10H14O), Carvacrol (C10H14O) and Parthenolide (C15H20O3) of feverfew on the viral protein of SARS-CoV-2. Parthenolide shows the best binding affinity with both main protease (Mpro) and papain-like protease (PLpro). The molecular electrostatic potential and Mulliken atomic charges of the Parthenolide molecule shows the high chemical reactivity of the molecule. The docking of Parthenolide with PLpro give score of −8.0 kcal/mol that validates the good binding of Parthenolide molecule with PLpro. This complex was further considered for molecular dynamics simulations. The binding energy of the complex seems to range in between −3.85 to −11.07 kcal/mol that is high enough to validate the stability of the complex. Free energy decomposition analysis have been also performed to understand the contribution of residues that reside into the binding site. Good binding affinity and reactivity response suggested that Parthenolide can be used as a promising drug against the COVID-19.
