Starting from the structure of the novel nonpeptidic angiotensin II antagonist DuP 753, a series of more rigid analogues was prepared by replacing the biphenyl part of DuP 753 with a naphthalene ring. Five different regioisomers (compounds 6a-e) were synthesized, and receptor binding in rat smooth muscle cell preparations as well as inhibition of angiotensin II induced contraction of rabbit aortic
从新型非肽血管紧张素II拮抗剂DuP 753的结构开始,通过用萘环取代DuP 753的联苯部分,制备了一系列更刚性的类似物。合成了五种不同的区域异构体(化合物6a-e),并测量了大鼠平滑肌细胞制剂中的受体结合以及对血管紧张素II诱导的兔主动脉环收缩的抑制作用,并将效价的阶次与基于分子建模研究。发现与2,6-取代的区域异构体6d及其类似物7(咪唑取代基的异构体)最有效,但仍比DuP 753弱。然后制备四氢萘衍生物,该四氢萘衍生物在酸性官能团的α位具有和不具有额外的甲基,并且具有相同的2,6-取代模式(表III中列出的化合物),期望进一步提高效能。尽管羧酸衍生物13a,b在预期效价范围内显示出活性,但是令人惊奇的是,在用四唑取代羧酸官能团之后,没有观察到进一步的效价提高(化合物18a,b)。这些结果可能表明这些化合物不以与DuP 753相同的方式与AT1受体结合。令人惊讶地,在用四唑(化合物1
