  摘要：

  已经制备了一系列5-[[[1-（4'-羧基苄基）咪唑基]亚甲基]乙内酰脲，并作为体内和体外血管紧张素II（Ang II）拮抗剂进行了评估。乙内酰脲环上取代基的变化导致有效的和选择性的Ang II拮抗剂，在AT1受体具有纳摩尔IC50值，对AT2受体的亲和力可忽略不计。优选的取代基包括在R1上的正丁基和在R2上的烷基或杂芳基甲基取代基。R2取代基的选择部分取决于其log P的计算，因为在CLOGP和AT1结合亲和力之间观察到显着相关性。许多AT1拮抗剂共有的联苯四唑药效基团可以被例如4-碳甲氧基苯基取代基取代，从而在体外和体内产生有效的Ang II拮抗剂。该系列的代表性化合物是57，它在30 mg / kg po下使肾性高血压大鼠的平均动脉血压降低40％，在10 mg / kg po时降低25％。另外，该化合物在缺盐的正常血压猴子模型中有效，在口服10 mg / kg时最大降低血压27％。总之，这些化合物属于一类新的Ang

  Fluoride's new role: Selective and efficient monoreductions of imides can be achieved with polymethylhydrosiloxane (PMHS) and tetra‐n‐butylammonium fluoride (TBAF) as catalyst (see scheme). The system is characterized by good chemoselectivity, operational simplicity, and functional‐group tolerance; a concise mechanistic proposal was possible from in situ spectroscopic investigations.
