wake-promoting drug modafinil have been synthesized. The transporter inhibitory activity of both the cis and trans isomers of these 3,4-disubstituted piperidines in both their (+)- and (-)-enantiomeric forms was determined. These studies reveal that the (-)-cis analogues exhibit dopamine transporter/norepinephrine transporter (DAT/NET) selectivity as was previously reported for the (+)-trans analogues
合成了4-(4-氯苯基)哌啶类似物,每个类似物带有硫代乙酰胺侧链附肢,类似于在促醒药物莫达非尼中发现的类似物。测定了这些(,)-和(-)-对映体形式的3,4-二取代哌啶的顺式和反式异构体的转运蛋白抑制活性。这些研究表明(-)-顺式类似物表现出多巴胺转运蛋白/去甲肾上腺素转运蛋白(DAT / NET)的选择性,如先前报道的(+)-反式类似物。另一方面,(-)-反式和(+)-顺式异构体具有5-羟色胺转运蛋白(SERT)或SERT / NET选择性。其中,(+)-cis-5b对NET表现出较低的纳摩尔Ki,在DAT和SERT处的效能分别降低39倍和321倍,因此,它成为探索与NET相关的行为特征的有用的药理研究工具。另一方面,本文所述的几种化合物,例如(+)-trans-5c,在所有三个转运蛋白上均显示出可比的活性。由于广谱转运蛋白抑制剂被认为比抗SERT或SERT + NET选择性抑制剂具有更
