The synthesis and pharmacological activity of new nonpeptide angiotensin II (AII) receptor antagonists are presented. These [1,2,4]-triazolo[1,5-c]pyrimidine and 1,2,4-triazolo[4,3-c]pyrimidine derivatives represent a new class of bicyclic antagonists that produced a potent, oral antihypertensive activity in the renal artery-ligated rat model. In vitro, they displayed a high affinity for rat adrenal
介绍了新的非肽血管紧张素II(AII)受体拮抗剂的合成和药理活性。这些[1,2,4]-三唑并[1,5-c]嘧啶和1,2,4-三唑并[4,3-c]嘧啶衍生物代表了一类新的双环拮抗剂,可产生有效的口服降压活性在肾动脉结扎的大鼠模型中。在体外,它们表现出对大鼠肾上腺AII受体的高度亲和力,并被发现对AT1受体亚型具有特异性。SAR研究表明,8- [2'-((1H-四唑-5-基)联苯-4-基]甲基对于口服活性很重要,并且烷基取代基在5和7位上起着至关重要的作用。在[1,5-c]和[4,3-c]系列之间没有发现显着差异。UP 269-6(5-甲基-7-正丙基8-[[2'-(1H-四唑-5-基)联苯-4-基]甲基]-[1,2,4]-三唑并[ 1,5-c]嘧啶-2(3H)-one,选择衍生物29)作为前导化合物。它被证明是一种高效的抗高血压衍生物(肾结扎大鼠在1 mg / kg po时平均动脉压降低39
