SARS-Cov-2 or COVID-19 has caused a global disaster and catastrophe which has consequently led to a pandemic for the last two decades, the world has faced coronaviruses similar to SARS-Cov-2 such as SARS-Cov and Mers-Cov. In this study, a wide range of proteins such as Plpro (Papain like Protease), Rdrp (RNA-Dependent-RNA-Polymerase), Mpro or 3cl Protease and Spike Protein. The selected proteins were listed retrieved from RCSB PDB(https://www.rcsb.org/) And Zhang lab (https://www.zhanglab.ccmb.med.umich.edu/COVID-19/) with their corresponding and respective PDB-ID. The 3d Structures or 2D Structures of these molecules were selected on the sole basis of resolved resolution (in Å)of the structures during the X-ray crystallography and Electron Microscopy. Structures were retrieved in .pdb format. The three dimensional ligand molecules were retrieved from PubChem chemical structure In Spatial Data Base (.SDF) format. The respective ligand molecules are;Hesperidin, Kaempferol, Quercetin, Epigallocatechin. This molecular docking shows significant data of polyphenols, flavonoids and bioflavonoids inhibiting SARS-Cov-2 proteins which could lead to conclusive data for treatment of polyphenols, flavonoids and bioflavonoids against SARS-Cov-2.
In-silico study of Hesperidin, Epigallocatechin (EGCG ), Kaempferol and Quercetin
