symmetrically bis-substituted imidazole analogs bearing at the N-1 and N-3 two biphenyl moieties ortho substituted either with tetrazole or carboxylate functional groups was designed based on docking studies and utilizing for the first time an extra hydrophobic binding cleft of AT1 receptor. The synthesized analogs were evaluated for their in vitro antagonistic activities (pA2 values) and binding affinities
基于对接研究并首次利用AT1的额外疏水结合裂隙设计了一系列在N-1和N-3两个邻位被四唑或羧酸酯官能团邻位取代的对称双取代双咪唑类似物受体。评估了合成的类似物的体外拮抗活性(pA 2值)和与血管紧张素II AT1受体的结合亲和力(–logIC 50值)。其中,钾(编辑逻辑50 = 9.04)和钠(编辑逻辑50 = 8.54)的4-丁基-盐Ñ,Ñ双[2' - (2 ħ-四唑-5-基)联苯-4-基]甲基}溴化咪唑鎓(分别为12a和12b),其游离酸11(–logIC 50 = 9.46)和4-丁基-2-羟甲基-N,N'-双[[2'-(2 H-四唑-5-基)联苯-4-基]甲基}溴化咪唑鎓(14)(–logIC 50 = 8.37,pA 2 = 8.58)显示出对N AT1受体具有很高的拮抗活性(效力)。效力与氯沙坦相似或什至更高(–logIC 50 = 8.25,pA 2 = 8
