ligand, several phenylethylamine derivatives were synthesized to evaluate their affinity to BzR. Some of these derivatives (17, 21, 24, 26, and 30) were found to exhibit high affinity (Ki = 0.51-0.085 microM) for BzR and possessed a partial agonist activity, although their chemical structure is closely related to tryptamine 2-6, tyramine 7-11, and dopamine 12-16 derivatives. A different interaction of these
测试了几种衍生物(其中色胺,酪胺和多巴胺部分通过草酰桥与吲哚核相连)具有取代牛脑膜上[3H]氟硝西m特异结合的能力。GABA比率和最有效化合物的体内测试表明,它们在苯二氮卓受体(BzR)上起反向激动剂的作用。为了更好地定义这种配体的结构-活性关系(SAR),合成了几种苯乙胺衍生物以评估其对BzR的亲和力。这些衍生物中的一些(17、21、24、26和30)被发现对BzR具有高亲和力(Ki = 0.51-0.085 microM),并具有部分激动剂活性,尽管它们的化学结构与色胺2密切相关。 6,酪胺7-11和多巴胺12-16衍生物。假设这些配体与受体位点有不同的相互作用。而且,所有制备的1-甲基衍生物都表现出对BzR的非常低的结合亲和力。
