4-diazepane analogs of N-(2-benzofuranyl)methyl-N′-(4-alkoxybenzyl)piperazines were prepared to explore the effect of ring contraction and expansion on σ receptor affinity and subtype selectivity within a series of cyclic diamines. In vitro receptor binding assays revealed that all cyclic vicinal diamines possessed affinity and selectivity for σ1 receptors. The imidazolidines possessed nanomolar σ1 affinities
制备了N-(2-苯并呋喃基)甲基-N '-(4-烷氧基苄基)哌嗪的咪唑烷和1,4-二氮杂类似物,以探讨环收缩和膨胀对一系列环中σ受体亲和力和亚型选择性的影响二胺。体外受体结合试验表明,所有的环状邻二胺所具有的亲和力和选择性σ 1受体。的咪唑烷类具有纳摩尔σ 1倍的亲和力(ķ我 = 6.45-53.5纳米),和亚型选择性的相对较低的水平(σ 2 / σ 1 = 58–237)。然而,哌嗪和diazepanes实现皮摩尔σ 1个相互作用,与ķ我分别范围0.05-10.28和0.10-0.194纳米,。此外,哌嗪和diazepanes显示出超过了极好的区分σ 2受体,具有σ 1个的分别143-16140和220-11542,选择性。
