A novel series of arylcyclopropanecarboxyl guanidines was synthesized and evaluated for activity against the sodium hydrogen exchanger isoform-1 (NHE-1). In biological assays conducted in an AP1 cell line expressing the human NHE-1 isoform, the starting cyclopropane 3a (IC(50) = 3.5 microM) shows inhibitory activity comparable to cariporide (IC(50) = 3.4 microM). Structure-activity relationships are
合成了一系列新的芳基环丙烷羧基胍,并评估了其对钠氢交换异构体-1(NHE-1)的活性。在表达人NHE-1亚型的AP1细胞系中进行的生物学分析中,起始环丙烷3a(IC(50)= 3.5 microM)表现出与甲立哌啶相当的抑制活性(IC(50)= 3.4 microM)。通过筛选芳基和环丙基环上的取代基的作用,使用结构活性关系优化各种酰基胍对NHE-1的亲和力。已证明在苯环上引入适当的疏水基团和在环丙烷环上引入宝石二甲基基团最多可将NHE-1抑制活性提高3个数量级(化合物7f,IC(50)= 0.003 microM)。此外,宝石二甲基系列类似物似乎在大鼠中显示出改善的口服生物利用度和更长的血浆半衰期。此外,与卡立哌利德相比,苯并二氢呋喃基铅类似物1(BMS-284640)表现出的NHE-1抑制活性提高了380倍以上,并且对NHE-1的选择性提高了。
