4-Benzylpiperidine is a drug and research chemical used in scientific studies. It acts as a monoamine releasing agent with 20- to 48-fold selectivity for releasing dopamine versus serotonin. It is most efficacious as a releaser of norepinephrine, with an EC50 of 109 nM (DA), 41.4 nM (NE) and 5246 nM (5-HT).[1] It has a fast onset of action and a short duration. It also functions as a monoamine oxidase inhibitor (MAOI) with preference for MAO-A.[2]

Synthesis

4-Cyanopyridine can be reacted with toluene to give 4-benzylpyridine.[3] Catalytic hydrogenation of the pyridine ring then completes the synthesis.[4]

Applications

RMI-10608 is a derivative of 4-benzylpiperidine and analog of haloperidol that was discovered to have potential use in treating psychosis and preventing brain damage by virtue of its NMDA antagonist pharmacology.[5] [6]
