binding were not the (1R)-2 beta, 3 beta-isomers but rather (1R)-2 beta, 3 alpha-4c and (1S)-2 beta, 3 alpha-4f. Conformational analyses show that these isomers exist in a flattened boat conformation with pseudoequatorial substituents. Thus, the binding data show that this conformation is recognized by the DAT-associated binding site and also suggest that this conformation of paroxetine is recognized by
(3S,4R)-4-(4-氟苯基)-3-[[3,4-(亚甲基二氧基)苯氧基]甲基]哌啶[(3S,9R)-3,帕罗西汀]是选择性5-羟色胺再摄取抑制剂(SSRI)在人类中用作抗抑郁药。在以前的研究中,我们报道了某些(1R)-3β-(取代的苯基)降冰片烷2β-羧酸甲酯(2a)对5-羟色胺转运蛋白(5-HTT)表现出高亲和力和合理的选择性。2a和(3S,4R)-3之间的主要结构差异是2a具有不同的绝对立体化学,并具有3中不存在的亚乙基桥。此外,2a具有与芳基环相邻的碳甲氧基取代基,而(3S, 4R)-3含有[3,4-(亚甲基二氧基)苯氧基]甲基。在这项研究中,我们介绍了3-(4-氟苯基)-2-[[3,4-(亚甲基二氧基)苯氧基]甲基]降冰片烷++(4)。抑制[3H]帕罗西汀结合的数据表明,具有与帕罗西汀相同的立体化学的(1R)-2 beta,3 alpha-4c对5-HTT具有最高的亲和力。令人惊讶的是,抑制[3H]
