The synthesis and pharmaceutical activity of new potent non-tetrazole angiotensin II (Ang II) receptor antagonists were described. These compounds were fluorine substituted derivatives of Losartan, Valsartan and Irbesartan with carboxylic acid group as replacements to the known potent tetrazole moiety at the 2′-biphenyl position. Their activities were evaluated by Ang II receptor binding assay as well
描述了新型有效的非四唑类血管紧张素II(Ang II)受体拮抗剂的合成和药物活性。这些化合物是具有羧酸基团的氯沙坦,缬沙坦和厄贝沙坦的氟取代的衍生物,其具有羧酸基团作为在2'-联苯位置上的已知有效四唑部分的替代物。通过Ang II受体结合测定以及体内测定来评估它们的活性。所有合成的化合物均显示出对AT 1受体亚型的纳摩尔亲和力。体内生物学评估表明,化合物1a,2和4在自发性高血压大鼠(SHR)和肾性高血压大鼠(RHR)中均产生剂量依赖性的降压作用。化合物4特别是在SHR中,以10 mg / kg的剂量服用后,在降低血压方面可以持续超过24小时,效果显着而持久,远胜于对照Losartan和Valsartan。化合物4还可以在体外和体内抑制前列腺癌。因此,化合物4被选作有效,新颖和持久的非四唑类抗高血压和抗肿瘤药物候选者,用于深入研究。
