Compounds 2b, 2d, and 2h were found to be the most potent, exhibiting a significant antiplatelet activity on arachidonic acid- and collagen-induced platelet aggregation. In addition, these new antiplatelet agents are free of gastric ulcerogenic effect and presented discrete anti-inflammatory and analgesic properties. The N-para-chlorophenyltriazolyl-4-acylhydrazone compound 2h produced the highest inhibitory
本文描述了属于N-取代-苯基-1,2,3-三唑-4-酰基hydr类(2a-p)的新型N-酰基hydr(NAH)化合物的设计,合成和药理学评价。将经典的杂芳环生物立体异构策略应用于先前报道的N-苯基吡唑基-4-酰基hydr衍生物1,由于其对花生四烯酸诱导的血小板聚集具有重要的抗聚集特性,因此被选为铅化合物(IC(50)= 24 +/- 0.5 micro M),由此产生了这个新系列2。这些新化合物2a-p易于合成,表征和在胶原蛋白(5 micro g / mL),ADP(5 micro M)和花生四烯酸诱导的血小板聚集测定中进行测试(100 micro M)在兔子的柠檬酸盐丰富的血浆中。发现化合物2b,2d和2h最有效,对花生四烯酸和胶原蛋白诱导的血小板聚集具有显着的抗血小板活性。另外,这些新的抗血小板药没有胃溃疡作用,并具有离散的抗炎和镇痛作用。N-对氯苯基三唑基-4-酰基hydr化合物2h对胶原蛋白(IC(50)=
