Overview
Mesoridazine (Serentil) is a piperidine neuroleptic drug belonging to the class of drugs called phenothiazines, used in the treatment of schizophrenia. It is a metabolite of thioridazine. The drug's name is derived from the methylsulfoxy and piperidine functional groups in its chemical structure.
It has central antiadrenergic, antidopaminergic, antiserotonergic and weak muscarinic anticholinergic effects.
Serious side effects include akathisia, tardive dyskinesia and the potentially fatal neuroleptic malignant syndrome.
Mesoridazine was withdrawn from the United States market in 2004 due to dangerous side effects, namely irregular heart beat and QT-prolongation of the electrocardiogram.[1]
It currently appears to be unavailable worldwide.
Chemistry
Mesoridazine (10-[2-(1-methyl-2-piperidyl)ethyl]-2-(methylsufinyl)phenothiazine) is synthesized by an analogous scheme to that seen already for thioridazine.
However, it is also synthesized by alkylating the acidic form of 2-methylthiophenothiazine -methylsulfonylphenothiazine- using 2-(2-chloroethyl)-1-methylpiperidine. 2-methylthiophenothiazine is initially acylated at the nitrogen atom using acetic anhydride, giving 10-acetyl-2-methylthiophenothiazine. The resulting acetyl derivative is further oxidized by hydrogen peroxide into 10-acetyl-2-methylsulfonylpenothiazine. Deacylation of this product in potassium carbonate methanol solution gives 2-methylsulfanylphenothiazine, which is alkylated by 2-(2-chlorethyl)-1-methylpiperidine in the presence of sodamide, affording the desired mesoridazine.
