Milipertine

Milipertine (INNTooltip International Nonproprietary Name, USANTooltip United States Adopted Name; developmental code name WIN-18935) is a drug described as an antipsychotic, neuroleptic, and tranquilizer which was under development for the treatment of schizophrenia but was never marketed.[1][2][3][4]

Structurally, it is a substituted tryptamine and a piperazinylethylindole.[5][6][7] The drug is closely structurally related to other "pertines" including alpertine, oxypertine, and solypertine, which are also tryptamines and piperazinylethylindoles.[5][6][8]

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.[9][10] Oxypertine, milipertine, and solypertine all antagonize the behavioral effects of tryptamine, a serotonin receptor agonist, and apomorphine, a dopamine receptor agonist, in animals.[9][11] ortho-Methoxyphenylpiperazine (oMeOPP) has been said to be a metabolite of milipertine, as well as of oxypertine and several other drugs.[12][13]

Milipertine produced troublesome side effects in clinical studies including orthostatic hypotension, drowsiness, extrapyramidal symptoms, elevated liver enzymes, and weight loss.[14][15][4] The side effects of milipertine occurred too frequently and at doses well below those producing antipsychotic effects and its development was abandoned.[14][15][4]

Milipertine was first described in the scientific literature by 1968.[1]
