4-dichlorophenyl)ethyl]-1,4-diazabicyclo[3.2.2]nonane (16)] show very weak sigma interaction. Comparison of the binding data of different N-substituted homologues of 1 with those of the 1-[2-(3,4-dichlorophenyl)ethyl]-4-alkylpiperazines suggests that the two nitrogen atoms of 1 are working in opposition to one another in terms of their sensitivity to steric bulk. The high binding affinity of the 1,4-diazabicyclo[4
作为我们先前研究(J. Med。Chem。1992,35,4334-4343)的继续,我们构象限制了sigma-受体配体2-(1-吡咯烷基)-N- [2-(3,4-二氯苯基)乙基] -N-甲基乙胺(1)掺入一系列同源的哌嗪3-9和均哌嗪10和11中,二氮杂双环壬烷和癸烷,桥头双环辛烷和壬烷以及其他其他化合物。使用[3H](+)-喷他佐辛在豚鼠脑膜sigma 1位点获得sigma-受体结合亲和力。研究表明,在哌嗪中发现的氮孤对取向提供最强的结合相互作用。其他氮孤对取向或代表1 [不可能的交错构象的化合物,如4- [2-(3,4-二氯苯基)乙基] -1,4-二氮杂双环[3.2]。2] nonane(16)]显示非常弱的sigma相互作用。比较1的不同N-取代同系物与1- [2-(3,4-二氯苯基)乙基] -4-烷基哌嗪的结合数据表明,1的两个氮原子彼此相反。就其对空间体积的敏感性而言。1,4-二氮杂双环[4
