Polyphenols exhibiting binding energy of −7.0 kcal/mol or lower (eight polyphenols) against RdRp of the SARS-CoV-2 are listed in Table 2 along with the ligand-amino acid interactions. Control compounds, GTP and remdesivir, exhibited the binding energy of −7.9 and −7.7 kcal/mol, respectively, against the SARS-CoV-2 RdRp. Eight polyphenols displayed significantly higher binding affinity among the selected hundred natural polyphenols docked against the SARS-CoV-2 RdRp, with binding energies of TF3, TF2b, TF1, TF2a, hesperidin, EGCG, myricetin and quercetagetin as −9.9, −9.6, −9.6, −9.3, −8.8, −7.3, −7.2 and −7.0 kcal/mol, respectively (highlighted in Table 1). Further, 2D LigPlot+ representation of RdRp and the above-mentioned eight polyphenols reveal the stable network of molecular interactions (see Table 2 and Figure S1 in the Supplementary Information).
