principles of drug design, the structures of picotamide and betrixaban were combined to design novel series of 2-methoxy-5-aminobenzamides. A total of twenty new compounds 1a-1t have been synthesized and evaluated for their antiplatelet aggregation activities in vitro. Methods: In the structural design of target compounds 1a-1t, the betrixaban was retained group characteristics and the picotamide was retained
目的:根据药物设计原则,将吡咯酰胺和贝曲沙班的结构结合起来,设计出一系列新颖的2-甲氧基-5-氨基苯甲酰胺。总共合成了二十种新化合物1a-1t,并对其体外抗血小板聚集活性进行了评估。 方法:在目标化合物1a-1t的结构设计中,贝曲沙班保留了基团特征,而吡咯酰胺保留了1、3、4位取代基。以2-甲氧基苯甲酸为起始原料,经硝化,酰化,氨化,还原和二次氨化5个步骤合成了化合物1a-1t。分别以ADP,花生四烯酸和胶原为诱导剂,以阿司匹林和picotamide为两种参考药物,通过Born试验评估了它们的体外抗血小板聚集活性。 结果:化合物1f(46.14%±0.07)对ADP的活性最高,其IC50值为0.17 µM,远优于两种对照药物阿司匹林(0.44 µM)和甲基吡咯酰胺(0.47 µM)。四种化合物1i(0.24 µM),1j(0.22 µM),1r(0.25 µM)和1t(0.24 µM)的I
