HIDE SMILES / InChI
(-)-3-(3-hydroxyphenyl)-N-n-propylpiperidine ((-)-3-PPP, also known as preclamol) has a dual action towards to dopamine D2 autoreceptor: it activates it and also acts concomitantly as an antagonist at postsynaptic DA receptors. It was shown, that (-)-3PPP/preclamol was a safe drug for study in the treatment of schizophrenia and may have antipsychotic efficacy. Besides, the motor effects of the drug were evaluated in nine patients with Parkinson's disease using a double-blind, placebo-controlled design. However, the small number of patients manifesting a clinically significant response and the frequently inconsistent effects could indicate that this class of agents may have relatively limited clinical utility.

Route of Administration: Intramuscular
In Vitro Use Guide
In vitro, both (+)- and (-)-3-PPP (preclamol) reduced basal DOPA accumulation with a similar order of potency (apparent EC50 = 2.1 and 1.0 microns, respectively) and maximal effect, although they were less potent than the D2 DA receptor agonist quinpirole (EC50 = 0.15 microM).
