The synthesis and sigma receptor affinity of a series of conformationally restricted derivatives of 2-(1-pyrrolidinyl)-N-[2-(3,4-dichlorophenyl)ethyl]-N-methylethylenedi amine (1) is described. The pyrrolidinyl (or N,N-dialkyl),ethylenediamine,N-alkyl, and phenylethyl portions of this sigma receptor pharmacophore were restricted by its incorporation into 1,2-cyclohexanediamine-, pyrrolidine-, piperidine-
描述了一系列2-(1-吡咯烷基)-N- [2-(3,4-二氯苯基)乙基] -N-甲基乙二胺(1)的构象受限衍生物的合成和sigma受体亲和力。该sigma受体药效基团的吡咯烷基(或N,N-二烷基),乙二胺,N-烷基和苯乙基部分受其并入1,2-环己烷二胺-,吡咯烷-,哌啶-,高哌啶-和四氢异喹啉-的限制。含有配体。使用[3H](+)-喷他佐辛在豚鼠脑匀浆中测定这些化合物的sigma受体结合亲和力。除一类外,所有的合成都通过适当的二胺前体的酰化和烷烃还原来实现,该二胺前体的合成也已有报道。sigma受体亲和力范围为1.34 nM(对于6)(1R,2R)-反-N- [2-(3,4-二氯苯基)乙基] -N-甲基的7-二氯-2- [2-(1-(吡咯烷基)乙基]四氢异喹啉(12)至455 nM -2-(1-吡咯烷基)环己胺[(-)-4]。在该置换试验中,(+)-戊唑嗪的Ki值为3.1 nM,而DTG和氟哌啶醇的Ki值分别为27
