Pyridyl-phenyl ether monoamine reuptake inhibitors: Impact of lipophilicity on dual SNRI pharmacology and off-target promiscuity

A novel series of pyridyl-phenyl ethers are disclosed, which possess dual 5-HT and NA reuptake pharmacology with good selectivity over dopamine reuptake inhibition. An analysis of the relationship between lipophilicity and pharmacology highlighted that potent dual SNRI activity was only achievable at c log P > 3.5. The series was found to possess significant polypharmacology issues, and we concluded that this off-target promiscuity was related to lipophilicity.

The series was found to possess significant polypharmacology issues, we concluded that this off-target promiscuity was related to high lipophilicity.Figure optionsDownload as PowerPoint slide
