Objectives: The objective of the study was to screen and assess the selected bioactive bioflavonoids in medicinal plants as potential coronaviruses (CoV) main protease (Mpro) inhibitors using molecular docking studies Methods: We have investigated several bioflavonoids which include apigenin, galangin, glycitein, luteolin, morin, naringin, resveratrol, and rutin Nelfinavir and lopinavir were used as standard antiviral drugs for comparison Mpro was docked with selected compounds using PyRx 0 8 and docking was analyzed by PyRx 0 8 and Biovia Discovery Studio 2019 Results: The binding energies obtained from the docking of 6LU7 with native ligand, nelfinavir, lopinavir, apigenin, galangin, glycitein, luteolin, morin, naringin, resveratrol, and rutin were found to be −7 4, −8 3, −8 0, −7 8, −7 3, −7, −7 4, −7 6, −7 8, −6 9, and −9 kcal/mol, respectively Conclusion: From the binding energy calculations, we can conclude that nelfinavir and lopinavir may represent potential treatment options and apigenin, galangin, glycitein, luteolin, morin, naringin, resveratrol, and rutin found to possess the best inhibitors of CoV disease-19 main protease
