synthesis and pharmacological profile of (S)-MK-26, a new modafinil analogue with markedly improved potency and selectivity for DAT over parent drug. Ex vivo electrophysiology revealed significantly augmented hippocampal long-term synaptic potentiation upon acute, intraperitoneally delivered (S)-MK-26 treatment, whereas in vivo experiments in the hole-board test showed only lesser effects on reference
多巴胺 (DA) 是人类大脑中最丰富的儿茶酚胺能神经递质,可调节年轻和衰老大脑中的关键行为和神经过程,包括运动、睡眠、注意力、情绪、学习和记忆以及社交和寻求奖励的行为。DA 转运蛋白 (DAT) 调节跨突触 DA 水平,影响所有这些过程。针对 DAT 的化合物(例如,可卡因和安非他明)在历史上被用于塑造情绪和认知,但这些物质通常会导致严重的负面副作用(耐受性、滥用、成瘾和依赖)。DA/DAT 信号传导功能障碍与神经精神和进行性脑部疾病有关,包括帕金森病和阿尔茨海默病、药物成瘾和痴呆,导致毁灭性的个人和家庭问题以及全球高昂的社会经济成本。因此,开发具有降低滥用责任并改善 DA/DAT 相关功能障碍的低副作用、新的/选择性药物在医学和保健领域至关重要。以大鼠为实验动物模型,本工作描述了(S )-MK-26,一种新的莫达非尼类似物,与母体药物相比,对 DAT 的效力和选择性显着提高。体外电生理学显示,急性、腹膜内递送

of a series of compounds based on these scaffolds, which resulted in several new selective DAT inhibitors and gave valuable insights into the structure-activity relationships. Introduction of the second chiral center and subsequent chiral separations provided all four stereoisomers, whereby the S-configuration on both generally exerted the highest activity and selectivity on DAT. The representative
