A novel series of substituted benzoylguanidine derivatives were designed and synthesized as potent NHE1 inhibitors. Most compounds can significantly inhibit NHE1-mediated platelet swelling in a concentration-dependent manner, among which compound 5f (IC50 = 3.60 nM) and 5l (IC50 = 4.48 nM) are 18 and 14 times respectively more potent than cariporide (IC50 = 65.0 nM). Furthermore, when tested in vivo
设计并合成了一系列新颖的取代苯甲酰基胍衍生物作为有效的NHE1抑制剂。大多数化合物都可以以浓度依赖性的方式显着抑制NHE1介导的血小板肿胀,其中化合物5f(IC 50 = 3.60 nM)和5l(IC 50 = 4.48 nM)的效力分别比卡立哌利特(IC 50)高18倍和14倍 = 65.0 nM)。此外,当在体内和体外进行测试时,化合物5f对SD大鼠心肌缺血-再灌注损伤的保护作用优于cariporide,是有希望进一步研究的潜在先导化合物。
