Discovery and pharmacological characterization of aryl piperazine and piperidine ethers as dual acting norepinephrine reuptake inhibitors and 5-HT1A partial agonists.
Compounds that are both norepinephrine reuptake inhibitors (NRI) and 5-HT1(A) partial agonists may have the potential to treat neuropsychiatric disorders including attention deficit hyperactivity disorder (ADHD) and depression. Targeted screening of NRI-active compounds for binding to the 5-HT(1A) receptor provided a series of thiomorpholinone hits with this dual activity profile. Several iterations of design, synthesis, and testing led to substituted piperidine diphenyl ethers which are potent NRIs with 5-HT1(A) partial agonist properties. In addition, optimization of these molecules provided compounds which exhibit selectivity for NRI over the dopamine (DAT) and serotonin (SERT) reuptake transporters. Monoamine and 5-HT(1A) in vitro functional activities for select compounds from the developed piperidine diphenyl ether series are also presented.
