A novel series of 3,5,6‐trimethylpyrazine‐2‐methoxy (or methylamino) substituted benzoyl‐guanidine derivatives were designed and synthesized as Na+/H+ exchange (NHE) inhibitors. In this study, compounds with electron‐withdrawing substituents on the benzene ring seemed to improve NHE‐1 inhibitory activities. Compounds 6d, 6k, and 6l were found to be potent inhibitors of NHE‐1 (IC50=3.0±1.6, 3.0±1.4
设计并合成了一系列新的 3,5,6-三甲基吡嗪-2-甲氧基(或甲氨基)取代的苯甲酰-胍衍生物作为 Na+/H+ 交换 (NHE) 抑制剂。在这项研究中,苯环上带有吸电子取代基的化合物似乎可以提高 NHE-1 的抑制活性。发现化合物 6d、6k 和 6l 是 NHE-1 的有效抑制剂(IC50=3.0±1.6、3.0±1.4 和 1.6±0.4 nmol/l,分别)。此外,他们在体内大鼠心肌梗塞模型中显示梗塞面积显着减少。
