piperazine in terms of 5-HT1A binding affinity. In fact, 1-cyclohexyl, 1-(3-benzisoxazolyl), 1-(benzothiazole-2-carbonyl), 1-(2-benzothiazolyl), 1-(2-quinolyl) substituted piperazines 21-30 displayed moderate or low 5-HT1A receptor affinity; on the contrary, 1-(3-benzisothiazolyl) and 1-(1-naphthalenyl) substituted piperazines 19, 20 and 32 displayed high 5-HT1A receptor affinity, the Ki values being in
在本论文中,我们报告了1取代的4- [3-(5-或7-甲氧基-1,2,3,4-四氢萘)在5-HT1A,D2和alpha1受体上的合成和结合情况-1-基)丙基]哌嗪衍生物19-32和一些相关的杂烷基衍生物33-35。将获得的结果与先前报道的1-苯基,1-(2-甲氧基苯基),1-(2-吡啶基)类似物2-9的结果进行比较。结果指出,就5-HT1A结合亲和力而言,连接在哌嗪N-1位的基团的关键作用。实际上,1-环己基,1-(3-苯并恶唑基),1-(苯并噻唑-2-羰基),1-(2-苯并噻唑基),1-(2-喹啉基)取代的哌嗪21-30显示中等或低5 -HT1A受体亲和力;相反,1-(3-苯并噻唑基)和1-(1-萘基)取代的哌嗪19,20和32显示出高的5-HT1A受体亲和力,Ki值在亚纳摩尔范围内。此外,与参考化合物2-9相比,化合物19、20和32表现出比alpha1受体更好的选择性。
