A series of novel Ligustrazine derivatives was designed, synthesized, and assayed for their protective effects on damaged ECV-304 cells and antiplatelet aggregation activities. The results showed that most Ligustrazine derivatives exhibited lower EC50 values for protective effects on the ECV-304 cells damaged by hydrogen peroxide in comparison with Ligustrazine. And some Ligustrazine derivatives presented better antiplatelet aggregation activities than Ligustrazine. The derivatives containing the bisphenylmethyl pharmacophore (7a-c) exhibited highest potency. Compound 7a displayed most potential protective effects on the ECV-304 cells damaged by hydrogen peroxide, and compound 7c was found to be the most active antiplatelet aggregation agent. Structure-activity relationships were briefly discussed. (c) 2007 Elsevier Ltd. All rights reserved.
