disubstituted imidazole AT(1) Angiotensin II (AII) receptor antagonist related to losartan with reversion of butyl and hydroxymethyl groups at the 2-, 5-positions of the imidazole ring was synthesized and evaluated for its antagonist activity (V8). In vitro results indicated that the reorientation of butyl and hydroxymethyl groups on the imidazole template of losartan retained high binding affinity to the
合成了一种新的 1,5 双取代咪唑 AT(1) 血管紧张素 II (AII) 受体拮抗剂,与氯沙坦相关,在咪唑环的 2-、5-位具有丁基和羟甲基的回复,并评估了其拮抗剂活性 (V8 )。体外结果表明,氯沙坦咪唑模板上的丁基和羟甲基基团的重新定向保留了对 AT(1) 受体的高结合亲和力,结论是 2,5- 位取代基的间距是最重要的。对接研究通过结合测定结果证实,其清楚地显示设计的化合物V8与原型氯沙坦的结合评分相当。一个高效的,
