selective sigma ligands as tools in the investigation of this site in psychosis. It was found that both hexa- and octahydrobenz[f]isoquinolines with lipophilic N-substituents had high affinities for the sigma site. Notably, trans-3-cyclohexyl-1,2,3,4,4a,5,6,10b-octahydrobenz[f]isoquinoline (26) had an affinity of 0.25 nM making it the highest affinity sigma ligand reported to date. Moreover, it is at least
本文描述了一些构象受限的4-苯基哌啶类似物的合成及其与豚鼠小脑sigma识别位点([3H] -DTG)和大鼠纹状体多巴胺D2受体([3H]-(-)-sulpiride)的亲和力。为了开发有效的选择性sigma配体作为对精神病学这个部位进行调查的工具。发现具有亲脂性N-取代基的六氢和八氢苯并[f]异喹啉对sigma位点都具有高亲和力。值得注意的是,反式-3-环己基-1,2,3,4,4a,5,6,10b-八氢苯并[f]异喹啉(26)的亲和力为0.25 nM,是迄今为止报道的最高亲和力sigma配体。此外,它对D2受体的选择性至少是10,000倍,并且可能被证明是σ位点研究的有价值的工具。其他类似物,例如1H-茚并[2,1-c]吡啶和1H-苯并[3,
