N-Benzyl-N-(pyrrolidin-3-yl)carboxamides as a new class of selective dual serotonin/noradrenaline reuptake inhibitors

The structure–activity relationship and the synthesis of novel N-benzyl-N-(pyrrolidin-3-yl)carboxamides as dual serotonin (5-HT) and noradrenaline (NA) monoamine reuptake inhibitors are described. Compounds such as 18 exhibited dual 5-HT and NA reuptake inhibition, good selectivity over dopamine (DA) reuptake inhibition and drug-like physicochemical properties consistent with CNS target space. Compound 18 was selected for further preclinical evaluation.
