摘要: 目的: 研究引入杂环类基团对6-（4-取代乙酰氨基苯基）-4,5-二氢-3（2H）哒嗪酮类化合物抗血小板凝集活性的影响。 方法: 设计合成未见报道的目标化合物10个,所有化合物均经过1H-NMR谱等确证;参考Born方法进行体外药理实验。 结果: 所有化合物都具有抗血小板凝集的活性,其中化合物（5）,（9）和（10）的抗血小板凝集活性明显优于MCI-154。 结论: 杂环基团的空间位阻和亲水性对化合物抗血小板凝集的活性有影响。

Abstract: Objective: To study the antiplatelet aggregative aclivity nf 6-（4-substituted acetamido-phenyl）-4,5-dihydro-3（2H）-py- ridazinones with different heterocylic groups. Methods: Ten target compounds were designed and synthesized.All of them were con- firmed by 1H-NMR spectra.Born method was applied for preliminary pharmacological test in vitro. Results: All of the target compounds were reported.The results of preliminary pharmacological test showed that all the target compounds exhibited potent antiplatelet aggre- gative activity to a certain extent.Compound （5）,（9） and （10） were better than MCI-154 in vitro. Conclusion:: The stereospecifie blockade and hydrophilieity of different heterocylic groups impacted the antiplatelet aggregative activity.-
