disease caused by platelet aggregation is a serious threat to human health, so antiplatelet aggregation has great significance to treat the disease. Since, purine derivatives are important molecules with antiplatelet aggregation activity, it is very essential to study the relationship between purine structure and antiplatelet aggregation effect, which could help us to find antithrombotic drugs.

血小板聚集引起的心血管疾病严重威胁人类健康,因此抗血小板聚集对该病的治疗具有重要意义。由于嘌呤衍生物是具有抗血小板聚集活性的重要分子,因此研究嘌呤结构与抗血小板聚集作用的关系对于寻找抗血栓药物非常重要。本文描述了以嘌呤结构为骨架的分子取代基的修饰,并评估了它们的抗血小板聚集活性。基于自组织分子场分析 (SOMFA) 对一系列合成的新型嘌呤衍生物进行 3D-QSAR 分析。显着相关系数 (SOMFA, r 2 = 0.821, r cv 2 = 0.807,F 值 = 283.500,SEE = 0.229),并使用测试集验证模型预测能力。结果表明,取代基的合理修饰可以为开发更有效的药物分子提供基础。

A series of novel N-6-alkyl(aryl)-2-alkyl(aryl)thioadenosines were synthesized, and their human antiplatelet aggregation activities were evaluated by the stimulation of adenosine 5'-diphosphate (ADP). Some of these compounds showed strong activity, among which compound 5b(11) displayed the highest activity with an IC50 value of 29 +/- 3 mu M. Furthermore, five compounds were tested against arachidonic acid (AA)-induced human platelet aggregation. The results showed that compound 5b(10) exhibited the highest activity with an IC50 value of 3 +/- 2 mu M. The adenosine derivatives substituted with a phenethyl group at the N-6 position and a methylthio or ethylthio group at the C-2 position displayed high antiplatelet aggregation activity.
