investigate the importance of the heterocyclic ring system in the structure of the cardiovascular drug diltiazem for its calcium channel blocking activity. The manuscript describes the design, synthesis, and biological testing of a total of 10 S-(p-methoxybenzyl), N-substituted thiosalicylamides as a series of non-cyclic compounds derived from diltiazem's structure. The new compounds maintained all diltiazem
当前的研究旨在调查杂环系统在心血管药物地尔硫卓的结构中对于其钙通道阻滞活性的重要性。该手稿描述了总共10种S-(对甲氧基苄基)N-取代的硫代水杨酰胺的设计,合成和生物学测试,这些是一系列衍生自地尔硫卓结构的非环状化合物。新化合物保留了除地西ze环系统外的所有地尔硫卓药效基团。新系列的钙通道阻滞作用的体外评估显示,IC50值为4.8-56.0 microM,具有中等活性。数据表明环系统对于活动不是必不可少的。然而,与地尔硫卓相比,它的缺乏导致活性显着下降(IC50 = 0.3 microM)。
