In our present investigation, a series of novel 4-methoxy-1,3-benzenediolyl-hydrazones were designed and synthesized, and their ability to inhibit platelet aggregation was evaluated by adenosine diphosphate (ADP) and arachidonic acid (AA). The structures of the synthesized compounds were conﬁrmed by spectral data. Results demonstrated that the activities of all compounds excelled the positive drug Picotamide (25.1 % inhibition rate) and seven compounds (PNN01, PNN03, PNN05, PNN07, PNN09, PNN12, PNN14) have efficiently inhibited platelet aggregation even higher than Clopidogrel (37.6 % inhibition rate) induced by AA. Among them, PNN07 (39.8 % inhibition rate) was considered as the most potent analogue. Evaluation of cytotoxic activity of the compounds against L929 cell line revealed that none of the compounds have signiﬁcant cytotoxicity. Thus, diolylhydrazones derives are potential to be antiplatelet aggregation inhibitors and maybe working in AA-induced selectively.
