A number of N-(indol-3-ylglyoxylyl)benzylamine derivatives were synthesized and tested for [3H]flunitrazepam displacing activity in bovine brain membranes. Some of these derivatives (9, 12, 14, 15, 17, 27, 34, 35, 38, 41, and 45) exhibited high affinity for the benzodiazepine receptor (BzR) with Ki values ranging from 67 to 11 nM. The GABA ratio and [35S]-tert-butylbicyclophosphorothionate binding
合成了许多N-(吲哚-3-基乙醛基)苄胺衍生物,并测试了牛脑膜中[3H]氟硝西m的置换活性。这些衍生物中的一些(9、12、14、15、17、27、34、35、38、41和45)显示出对苯二氮杂receptor受体(BzR)的高亲和力,Ki值为67至11 nM。对于最具活性的化合物,测定的GABA比和[35S]-叔丁基双环磷酸环硫酸酯结合数据表明,它们在BzR处引起功效谱,这取决于苄胺部分苯环上存在的取代基的种类。此外,延长苯环和侧链的酰胺基之间的距离(丙胺衍生物1-3)和缩短(苯胺衍生物46-54),使化合物的结合力大大降低。
