serotonin and norepinephrine transporters. From the structure-activity relationship study, the 3 beta-(4'-chlorophenyl)-2 beta-(3'-phenylisoxazol-5-yl)tropane (5d) emerged as the most potent and selective compound. The binding data for 2 beta-heterocyclic tropanes were found to show a high correlation with molecular electrostatic potential (MEP) minima near one of the heteroatoms in the 2 beta-substituents
设计,合成和表征了一组3个β-(4'-取代苯基)-2β-杂环托烷。我们发现这些化合物可以作为具有2个β-甲氧基甲氧基的相应WIN 35,065-2类似物的生物立体替代物。相对于5-羟色胺和去甲肾上腺素转运蛋白,几种化合物对多巴胺转运蛋白(DAT)表现出高亲和力和选择性。通过结构-活性关系研究,3β-(4'-氯苯基)-2β-(3'-苯基异恶唑-5-基)托烷(5d)成为最有效和选择性的化合物。发现2个β-杂环托烷的结合数据显示出与2个β-取代基中杂原子之一附近的分子静电势(MEP)最小值的高度相关性。相比之下,在2β-取代基附近的其他MEP最小值以及计算的log P或取代基体积中发现低相关性。这些定量的构效关系研究与在DAT上静电对这些WIN 35,065-2类似物的结合力的贡献是一致的。
