In order to search for drugs with protective effect against myocardial ischemic-reperfusion injury, a novel series of 4-[4-(2,3,4-trimethoxy-benzyl)-piperazin-1-ylmethyl]benzoylguanidine derivatives were designed and synthesized from methyl 4-methyl-3-nitrobenzoate via bromination, substitution, reduction, acylation, hydrolyzation and condensation, and their structures were characterized by MS, IR, 1H NMR techniques and elemental analysis. Na＋/H＋exchanger 1 (NHE1) inhibitory activity of twelve compounds 7 was evaluated in a rat platelet swelling assay, and the results show that most of the tested compounds possess NHE1 inhibitory effects, among which, the IC50 values of compounds 7g and 7l are 3.72 and 3.53 nmol•L－1 respectively, making them 3.2 and 3.4 times respectively more potent than cariporide (IC50＝12.1 nmol• L－1).
