The synthesis and pharmacological activity of new nonpeptide angiotensin II (AII) receptor antagonists are presented. These 5-O-substituted and 5-C-substituted 3-alkylpyrazole derivatives represent a new series of antagonists and have led to the discovery of compounds with potent oral antihypertensive activity in a 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5-O-取代的和5-C-取代的3-烷基吡唑衍生物代表了一系列新的拮抗剂,并导致在肾动脉结扎的大鼠模型中发现具有有效口服降压活性的化合物。在体外,它们显示出对大鼠肾上腺AII受体的高度亲和力。体内结构活性关系研究表明,4- [2'-(1H-四唑-5-基)联苯-4-基]甲基部分对于口服活性很重要,并且烷基取代基在1-的关键作用或2位。在口服给药的情况下,总体上发现5-C衍生物比5-O衍生物更有效。UP 221-78,5-羟甲基-3-正丙基-1-(2,2,2-三氟乙基)-4- [[2'
