1-[1-(2-Benzo[b]thiopheneyl)cyclohexyl]piperidine hydrochloride (BTCP, 1) and cocaine bind to the neuronal dopamine transporter to inhibit dopamine (DA) reuptake. However, on chronic administration, cocaine produces sensitization, but 1 produces tolerance. Because metabolites of 1 might be responsible for some of its pharmacological properties, we have identified the primary metabolites of 1 produced
1- [1-(2-苯并[b]噻吩基)环己基]哌啶盐酸盐(BTCP,1)和可卡因与神经元多巴胺转运蛋白结合,以抑制多巴胺(DA)的再摄取。但是,在长期给药时,可卡因会产生致敏作用,但1会产生耐受性。因为1的代谢物可能是其某些药理特性的原因,所以我们确定了大鼠肝微粒体产生的1的主要代谢物,并确定了它们对DA转运蛋白的亲和力。通过与HPLC和GC系统中的合成标准品进行比较,鉴定出五种单羟基化衍生物(3、5、9、10、14)和两种降解化合物(15、16)为代谢物。使用先前用于合成苯环利定代谢物的合成方案获得标准品。在体外,有两种化合物(3,5)显示出对DA转运蛋白的高亲和力。这些活性代谢物可能在1.的药理学中很重要。
