In Silico Molecular Docking Analysis of Myricetin, Fisetin, and Kaempferol Against Spike Protein SARS-CoV-2 Omicron: Opening Possibilities for the Drug Discovery Against SARS-CoV-2 Omicron

The SARS-CoV-2 Omicron was classified as a pestilent in early 2022 and is familiar to be caused by the Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV2 omicron). Many researchers in the research-based world are demanding to discover a way to find an amicable solution to prevent or cure this disease by using flavonoids. Numerous studies have shown that flavonoids can be very effective in viral infections. This study aimed to carry out molecular docking of Myricetin, Fisetin, and Kaempferol against the spike protein SARS-CoV-2 omicron (PDB ID: 7qo7) protein. The PyRx visual docking tool and BIOVIA discovery studio visualizer software was used to estimate ligand-receptor interactions. According to the findings of this docking investigation, certain flavonoids interact with the target spike receptor protein with a binding capacity of − 6.1 to − 7.3 kcal/mol. The present study concludes that out of selected ligands, Kaempferol showed maximum binding affinity and could be the best hinder of SARS-CoV-2 Omicron.
