from our previously reported high affinity sigma receptor ligands (1S,2R)-(-)-N-[2-(3,4-dichlorophenyl)-ethyl]-N-methyl-2-(1- pyrrolidinyl)cyclohexylamine [(-)-2] and (+)-2, we have identified a novel class of superpotent (subnanomolar affinity) sigma ligands specific for the sigma receptor labeled by [3H]-(+)-3-PPP. When 3 was tested for its capacity to displace [3H]-(+)-3-PPP from guinea pig brain membranes
通过合成和测试零件结构,N- [2-(3,4-二氯苯基)乙基] -N-甲基-2-(1-吡咯烷基)乙基胺(3)源自我们先前报道的高亲和力σ受体配体(1S,2R)-(-)-N- [2-(3,4-二氯苯基)-乙基] -N-甲基-2-(1-吡咯烷基)环己胺[(-)-2]和(+)-参见图2,我们已经鉴定出一类新型的对[3H]-(+)-3-PPP标记的σ受体具有特异性的超强(亚纳摩尔亲和力)σ配体。测试3从豚鼠脑膜置换[3H]-(+)-3-PPP的能力时,其Ki值为0.34 nM,优于其母体化合物(-)-2(Ki = 1.3 nM)和(+)-2(Ki = 6.0 nM)。与3相关的其他化合物,例如N- [2-(3,4-二氯苯基)乙基] -N-甲基-2-(1-高哌啶基)乙胺(19)的Ki = 0.17 nM [(3H]-(+ )-3-PPP)。通过以多种不同方式操纵该结构来检查3的高sigma受体亲和力
