Some 3,3-dimethyl-1-(3-naphthylpropyl)piperidine and 1-cyclohexyl-4-(3-naphthylpropyl)piperazine derivatives, structurally containing naphthol as a fluorescent moiety, were prepared for being potentially used as fluorescent sigma ligands. Structurally related analogs were also prepared, where the naphthalene nucleus was replaced by the fluorescent carbazole moiety and chain length was varied. For all
制备了一些结构上含有
萘酚作为荧光部分的3,3-二甲基-1-(3-
萘基丙基)
哌啶和1-环己基-4-(3-
萘基丙基)
哌嗪衍
生物,它们有可能被用作荧光σ
配体。还制备了结构相关的类似物,其中
萘核被荧光
咔唑部分取代,并且链长变化。对于所有化合物,均测量了对sigma受体和Delta8-Delta7
固醇异构酶位点的体外亲和力,并确定了荧光性质。化合物19的sigma受体亲和力(sigma1,Ki = 6.78 nM和sigma2,Ki = 26.4 nM)和荧光特征均给出了最佳结果。因此,它被选择用于sigma受体的体外饱和结合分析。
