Docking interactions of EGCG and TF3 with druggable targets of SARS-CoV-2. The first column represents EGCG and the second column represents TF3. The rows present: a) 3Clpro b) spike RBD 3) PLpro 4) RdRp 5) ACE2 receptor with spike RBD. The dotted green line indicates hydrogen bonding, amino acids in green colour indicate can der Waals interactions, orange dotted line represents pi-anion or pi-cation interaction, the pink dotted line represents a pi-alkyl bond, the purple dotted line indicates pi-sigma or pi-pi bond, yellow dotted line represent a pi-sulphur bond, a cyan dotted line indicates a halogen bond and red dotted line represents unfavourable interaction.
