    名称:
    新型苯并二氮杂receptor受体部分激动剂:恶二唑基咪唑并苯并二氮杂s。
    摘要:
    报道了一系列与苯二氮卓拮抗剂Ro 15-1788(2a)有关的咪唑基苯并二氮杂卓的恶二唑衍生物的合成和生化评估。尽管恶二唑环被看作是酯键的等排替代物,但观察到结构活性趋势上的显着差异。具体而言,相对于相应的酯,恶二唑9-12始终具有增加的受体功效(通过测量GABA位移证明)。另外,与经典的激动剂如地西epa形成鲜明对比的是,通过7-而不是8-卤素取代基增强了对苯并二氮杂receptor受体的亲和力。根据最初基于2a的X射线结构的六点受体结合模型讨论了结果。为了比较,确定了分别具有6-氧代和6-苯基基团的两种代表性恶二唑衍生物10h和12o的晶体结构,并将数据纳入了改良的结合模型中,以说明这些化合物的更高功效。结论是2a的拮抗行为取决于酯羰基氧的氢键受体性质,而对于恶二唑系列,该位点位于咪唑氮上。
