Fig. 6From: Identification of the anti-breast cancer targets of triterpenoids in Liquidambaris Fructus and the hints for its traditional applicationsBinding sites of LF triterpenoids on PARP1. a LF08 could form hydrogen bound with the backbone of Arg878 and the sidechain of Asp770 on AD site; b Besides binding on AD site, LFc could form C-H···π interaction with Tyr896 on NI site, and form hydrogen bound with Glu763 on PH siteBack to article page
