related to BTCP exhibited greater selectivity for sites labeled by [3H]BTCP. However, several of the BTCP-related derivatives showed greater (compared with BTCP and cocaine) ability to displace [3H]cocaine. Most notably, 1-[1-(2-benzo[b]thienyl)cyclohexyl]pyrrolidine (7) exhibited a 3.4-fold greater affinity for these sites compared with BTCP and a 9-fold greater affinity at these sites than cocaine
高亲和力多巴胺(DA)摄取抑制剂1- [1-(1-(2-苯并[b]噻吩基)环己基]哌啶(BTCP,3)的哌啶和环己基环同系物均由适当的环烷酮分四个步骤制备。测试了这些化合物在大鼠纹状体匀浆中置换[3H] BTCP和[3H]可卡因并抑制[3H] DA摄取的能力。IC50([3H]可卡因)/ IC50([3H] BTCP)的比值范围从BTCP的62至1- [2-(苯并[b]噻吩基)-环戊胺的1.5(17);可卡因的比率为0.6。这表明在所有测试的[3H] BTCP标记位点的化合物中,BTCP的选择性最高,而可卡因对[3H]可卡因标记的位点的选择性最高。这些化合物取代[3H] BTCP和[3H]可卡因的相对能力的巨大差异表明,这两种放射性配体标记了转运蛋白上的不同位点。通常,与BTCP结构相关的化合物对由[3H] BTCP标记的位点表现出更大的选择性。但是,一些与BTCP相关的衍生物显示出更高的
