and the semi-synthesis of analogue 4, with a furan ring, and compound 5, without a planar D-ring, are described. Studies into the antitumor activity of these compounds suggest that the five-membered unsaturated lactone ring (D-ring) of triptolide is essential to its potent anticancer activity and the C18 carbonyl group may exert an important influence on the interaction between triptolide and the target

systematic structure–activityrelationshipstudies have not yet been reported. Here, four types of Dring‐modified triptolide analogues were designed, synthesized and evaluated against human ovarian (SKOV‐3) and prostate (PC‐3) carcinoma cell lines. The results suggest that the Dring is essential to potency, however it can be modified, for example to C18 hydrogen bond acceptor and/or donor furan ring analogues
