3-PPP (N-n-propyl-3-(3-hydroxyphenyl)piperidine) is a mixed sigma σ1 and σ2 receptor agonist (with similar affinity for both subtypes, though slightly higher affinity for the latter) and D2 receptor partial agonist which is used in scientific research. It shows stereoselectivity in its pharmacodynamics. (+)-3-PPP is the enantiomer that acts as an agonist of the sigma receptors; it is also an agonist of both D2 presynaptic and postsynaptic receptors. Conversely, (−)-3-PPP, also known as preclamol (INNTooltip International Nonproprietary Name), acts as an agonist of presynaptic D2 receptors but as an antagonist of postsynaptic D2 receptors, and has antipsychotic effects. 3-PPP has also been reported to be a monoamine reuptake inhibitor and possibly to act at adrenergic receptors or some other non-sigma receptor.
Synthesis
The Grignard reagent was prepared for 3-Bromoanisole (1) and this was reacted with 3-Bromopyridine (2) to give 3-(3-methoxyphenyl)pyridine (3). Reaction with 1-bromopropane occurred to give the quaternary salt PC13695099 (4a). {Alternatively catalytic hydrogenation of 3 could be attempted directly to give 3-(3-methoxyphenyl)piperidine (4b). A second reductive amination with propionic acid was then performed.} Catalytic hydrogenation of the quat cation gave 3-(3-methoxyphenyl)-1-propylpiperidine (5). Demethylation with hydrogen bromide then completed the synthesis of preclamol (6).
