a derivative that could serve as a cocaine inhibitor. A compound that blocks binding of the cocaine analog carboxyfluorotropane (CFT), allows dopamine uptake and exhibits low side effects could serve as a good candidate for that purpose. All analogs were tested for the extent to which they inhibit CFT binding, dopamine uptake and n-methyl scopolamine (NMS) binding. Several structure-function relationships
一系列的三己基苯基(THP)类似物用于寻找可以用作可卡因抑制剂的衍生物。阻止可卡因类似物羧基氟代烷(CFT)结合,允许多巴胺摄取并表现出低副作用的化合物可以用作该目的的良好候选者。测试了所有类似物抑制CFT结合,多巴胺摄取和正甲基东pol碱(NMS)结合的程度。出现了几种结构功能关系。与THP苯环的甲基化/卤化相比,该化合物阻断CFT结合的能力与其阻断多巴胺摄取的能力相比有所提高(5a-e)。用苯环取代环己基环往往会产生对多巴胺转运蛋白的亲和力较低的化合物(7b相比THP,7d相比5h,7c与8c相比)和THP哌啶环的修饰倾向于增强与多巴胺转运蛋白的亲和力(5f-h,8a,8c)。研究了一种几乎没有毒蕈碱活性的类似物(5f),这表明它可能具有很少的副作用,作为其体内可卡因抑制剂的作用已得到研究。但是,它在体内几乎没有拮抗作用。然而,这项工作极大地阐明了潜在可卡因抑制剂所需的结构-功能关系,
