Berbamine showed the strongest affinity to Mpro although ascorbic acid showed the weakest binding power. Three phytochemicals of B. asiatica (Berbamine, Oxyacanthine, and Rutin) show their inhibitory action by representing a reduced binding power score (larger docking scores) compared with the binding power of X77 ( 8.four kcal mol 1). Berbamine, Oxyacanthine, and Rutin were discovered to bind at the active web site of Mpro with docking scores of 9.7 kcal mol 1, -8.five kcal mol 1, and -8.4 kcal mol 1 respectively (Table 2). The molecular docking result suggested that screened compounds may perhaps possess the exact same mechanism of action as the reference molecule. Hence, it is really evident that screened phytochemicals from B. asiatica have very good possible against Mpro. Then, all these three compounds in conjunction with X77 have been additional used for molecular interaction evaluation of protein-ligand complicated. The 2D interactions of the screened phytochemicals, also as reference ligand X77, have been visualized by Discovery studio visualizer.
