diastereomeric separation, as well as improvements in potency and pharmacokinetics were desirable for discovering pipeline drug candidates. Thus, a series of bis(4-fluorophenyl)methyl)sulfinyl)alkyl alicyclic amines, where the piperazine-2-propanol scaffold was modified, were designed, synthesized, and evaluated for binding affinities at DAT, as well as the serotonin transporter and σ1 receptors.

非典型多巴胺转运蛋白 (DAT) 抑制剂已在精神兴奋剂滥用的临床前模型中显示出治疗潜力。在大鼠中,1-(4-(2-((双(4-氟苯基)甲基)亚磺酰基)乙基)-哌嗪-1-基)-丙-2-醇 ( 3b ) 可有效降低两者的增强作用可卡因和甲基苯丙胺,但本身没有表现出精神兴奋行为。虽然3b的进一步开发正在进行中,但非对映异构体分离以及效力和药代动力学的改进对于发现管道候选药物是可取的。因此,设计、合成了一系列双(4-氟苯基)甲基)亚磺酰基)烷基脂环胺,其中对哌嗪-2-丙醇支架进行了修饰,并评估了其在 DAT 的结合亲和力,以及血清素转运蛋白和σ1个受体。在该系列中,14a显示出比3b ( K i = 230 nM)更高的 DAT 亲和力 ( K i = 23 nM) 、人肝微粒体中的中等代谢稳定性和 hERG/DAT 亲和力比 = 28。而14a相对于运动活性增加对于载体,它明显低于可卡因产生的活
