Abstract The coronavirus outbreak of 2019 (COVID‐19) has been seen as a global health concern. The 3‐chymotrpsin‐like protease or SARS‐CoV‐2 main protease, whose ability to control the coronavirus replication, has been a promising target for developing drugs against coronavirus infection. In this study, we used the molecular docking approach to screen natural compounds from traditional medicinal plants in Vietnam to find the possible inhibitors of SARS‐CoV‐2 main protease. The docking results revealed that among 170 compounds, the top 15 compounds with the high binding affinity to 3CL protease (PDB ID: 6WNP) might act as promising anti‐SARS‐CoV‐2 molecules. Among these compounds, Gracillin and Proanthocyanidins showed the highest binding affinity with a docking score of ‐9.2 Kcal/mol. However, further experiments are required for developing possible natural therapeutic medications for combating this coronavirus.

Abstract An exclusive approach towards the synthesis of novel 3‐(hydroxymethyl)‐2‐phenyl‐2,3 dihydroquinolin‐4(1H)‐one and it's in‐silico evaluation as inhibitor of COVID‐19 main protease. The one‐pot synthesis of an established procedure Claisen ester condensation reaction was sodium hydride mediated with intramolecular cyclization with solvent free conditions. The structures of the synthesized compound were confirmed by IR, 1H,13C NMR, and EI‐MS spectral studies. Chemo‐informatics study showed that the compound obeyed the Lipinski's rule, PASS, Swiss ADME. Computational docking analysis was performed using PyRx, AutoDock Vina option based on scoring functions. In‐silico molecular docking study results demonstrated Greater binding energy and affinity to the active pocket the N3 binding site of the Coronavirus primary protease.
