Visualization of interacting amino acid residues of SARS-CoV spike protein with ligands in 3D (i) and 2D (ii) representation. Ligands in stick representation are presented in different colors. a Green: nelfinavir mesylates (S3) b Red: 7-deacetoxy-7-oxogedunin. c Blue: 3-friedelanone.. Types of interactions are represented by green-dotted lines: H-bond interactions, light purple-dotted line: hydrophobic interactions (Pi-Alkyl, Alkyl, and pi-stacking) purple-dotted line: Pi-Pi T-shaped, yellow-dotted lines: Pi-sulphur interactions, pi-stacking interactions
