Twenty-two compounds of substituted benzoylguanidine derivatives were designed and synthesized as potent NHE1 inhibitors. Twelve compounds showed more potent NHE1 inhibitory activity than cariporide. The activities of compounds 7e, 7h and 7j (IC50 = 0.073 ± 0.021, 0.084 ± 0.012 and 0.068 ± 0.021 nmol/L, respectively) were two orders of magnitude higher than that of cariporide (30.7 ± 2.5 nmol/L).

设计并合成了22种取代的苯甲酰胍衍生物作为有效的NHE1抑制剂。十二种化合物显示出比甲立哌啶更有效的NHE1抑制活性。化合物7e,7h和7j的活性(IC 50分别 为0.073±0.021、0.084±0.012和0.068±0.021 nmol / L)比甲哌利肽(30.7±2.5 nmol / L)高出两个数量级。心肌细胞体外筛选显示7j对缺氧/复氧的心肌细胞具有突出的保护作用。因此,对于进一步的研究是有价值的。
