Amino acid interactions of terpenoids in substrate binding cavity of human TMPRSS2. S Surface representation. Ligands in sticks representation are represented by colors. a Red: camostat. b Blue: 11-hydroxy-2-(3,4-dihydroxybenzoyloxy)abieta-5,7,9(11),13-tetraene-12-one. c Green: 11-hydroxy-2-(4-hydroxybenzoyloxy)-abieta-5,7,9(11),13-tetraene-12-one. 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
