unambiguously by X-ray crystal structural study. One of the enantiomers, compound S,S-(-)-19a, exhibited the highest potency for the DAT (IC50 = 11.3 nM) among all the compounds tested and was as potent as GBR 12909 (1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(3-phenylpropyl)piperazine). However, the compound (-)-19a was more selective than GBR 12909 in binding to the DAT compared with binding to the
探索结构-活性关系(SAR)的新型构象约束顺式-3,6-二取代哌啶衍生物衍生自(2,2-二苯乙基)-[1-(4-氟苄基)哌啶-4-基甲基]胺( I),通过衍生化铅的3位上的环外N原子,合成了一系列化合物。这项研究导致了取代苯基和杂环衍生物的形成。通过测量其竞争[3H] WIN 35 428,[3H]结合的能力,测试了所有新化合物在脑中对多巴胺转运蛋白(DAT),血清素转运蛋白(SERT)和去甲肾上腺素转运蛋白(NET)的亲和力。 ] citalopram和[3H] nisoxetine。还评估了所选化合物在抑制[3H] DA摄取方面的活性。SAR结果表明,苯环上取代的性质对于DAT的活性很重要,因为存在一个吸电子基团,该吸电子基团对效能的影响最大。杂环基团取代苄基中的苯环导致开发出对DAT具有中等活性的化合物。通过非对映异构体分离方法分离了两种最有效的外消旋化合物,并观察到对映异构体的亲和
