N,O-Dimethyl-4β-(2-naphthyl)piperidine-3β-carboxylate (DMNPC) is a piperidine based stimulant drug which is synthesised from arecoline. It is similar to nocaine in chemical structure, and has two and a half times more activity than cocaine as a dopamine reuptake inhibitor. However it is also a potent serotonin reuptake inhibitor, with similar affinity to fluoxetine.[1] It is a structural isomer of another potent dopamine reuptake inhibitor, HDMP-28.

Clearly it is not just the SS enantiomer of the title compound that is an active MAT inhibitor.

Effect of N-demethylation

For the SR enantiomer, increased DAT affinity is seen upon demethylation.

This is the same choice of isomer used in the production of Paxil.
