hypothesis proposed for binding to the benzodiazepine receptor site. Comparison of B.1 with 1,2,3-triazole derivatives bearing a bicyclic substituent in position 1 of the heterocyclic ring suggests that a high steric hindrance increases the affinity of a compound for the benzodiazepine receptor.
制备某些1,2,3-三唑衍生物并测试其取代与牛脑膜蛋白结合的[3H]地西ze的能力。除B.1以外,所有测试的化合物基本上都缺乏这种能力,B.1在2.5 microM的试验中有50%抑制了[3H]地西am的结合。具有酸性特性的1,2,3-三唑环的B.1结构支持提出的与苯并二氮杂receptor受体位点结合的假设。B.1与在杂环的1位带有双环取代基的1,2,3-三唑衍生物的比较表明,高位阻增加了化合物对苯并二氮杂pine受体的亲和力。
