A series of novel acylpiperazinyl Ligustrazine derivatives was designed, synthesized, and their protective effects on damaged ECV-304 cells and antiplatelet aggregation activities were evaluated. The results showed that compound E33 displayed most potential protective effects on the ECV-304 cells damaged

A series of novel ligustrazinyloxy-cinnamic acid derivatives were designed, synthesized and evaluated for their inhibitory effect on adenosine diphosphate (ADP)-induced platelet aggregation in vitro, and also assayed for their protective effect against hydrogen peroxide (H(2)O(2))-induced oxidative damage on ECV-304 cells.

A new anticancer ligustrazine derivative, 3beta-hydroxyolea-12-en-28-oic acid-3,5,6-trimethylpyrazin-2-methyl ester (T-OA, C38H58O3N2), was previously reported. It was synthesized via conjugating the effective antitumor ingredients of a classic traditional Chinese medicine (TCM) formulation. In the present study, anticancer efficacy of T-OA was evaluated
