Substituted norbenzomorphans are known to display high affinity and selectivity for the two sigma receptor (σR) subtypes. In order to study the effects of simplifying the structures of these compounds, a scaffold hopping strategy was used to design several novel sets of substituted isoindolines, tetrahydroisoquinolines and tetrahydro-2-benzazepines. The binding affinities of these new compounds for
已知被取代的去甲苯并吗啡烷对两种sigma受体(σR)亚型表现出高亲和力和选择性。为了研究简化这些化合物的结构的效果,使用支架跳跃策略设计了几组新颖的取代异吲哚啉,四氢异喹啉和四氢-2-苯并ze庚因。确定了这些新化合物对sigma 1(σ1R)和sigma 2(σ2R)受体的结合亲和力,并鉴定了一些具有高亲和力的类似物(K i ≤25 nM)和对σ1R或σ2R的显着选择性(> 10倍)。通过建模研究预测了所选化合物与σ1R的优选结合方式,芳香环上的取代基和双环骨架氮原子的取代基的性质似乎影响了σ1R-优先配体的优选结合方向。
