Fig. 3From: Combination of bioaffinity ultrafiltration-UFLC-ESI-Q/TOF-MS/MS, in silico docking and multiple complex networks to explore antitumor mechanism of topoisomerase I inhibitors from Artemisiae Scopariae HerbaBinding profiles of topo I inhibitors from ASH extract. PDB ID of topo I is 1T8I. a, Interactions of hydroxygenkwanin and topo I. b, Interactions of chlorogenic acid and topo I. Light pink line indicates π-alkyl ineraction. Dark pink line indicates π-π stacked. Orange line indicates π-anion interaction. Light green line indicates carbon hydrogen bond. Green line indicates van der Waals force. Dark green line indicates conventional hydrogen bondBack to article page
