Alpertine (INNTooltip International Nonproprietary Name, USANTooltip United States Adopted Name; developmental code name WIN-31665) is a drug described as an antipsychotic, neuroleptic, and tranqulizer which was never marketed.[1][2][3]

Structurally, it is a substituted tryptamine and a piperazinylethylindole.[4] The drug is closely structurally related to other "pertines" including milipertine, oxypertine, and solypertine, which are also tryptamines and piperazinylethylindoles.[4]

The related drug oxypertine shows high affinity for the serotonin 5-HT2 and dopamine D2 receptors (Ki = 8.6 nM and 30 nM, respectively) and is also known to act as a catecholamine depleting agent.[5][6] Oxypertine, milipertine, and solypertine all antagonize the behavioral effects of tryptamine, a serotonin receptor agonist, and apomorphine, a dopamine receptor agonist, in animals.[5][7] Conversely however, alpertine was not effective, at least at doses of up to 10 mg/kg.[5][7] ortho-Methoxyphenylpiperazine (oMeOPP) has been said to be a metabolite of the related drugs milipertine and oxypertine.[8][9]

Alpertine was first described in the scientific literature by 1971.[1]
