Application

Cyamemazine has been used as an internal standard and antipsychotic drug to spike plasma samples in mass spectrometry studies. It has also been used as an analytical standard in gas chromatography-tandem mass spectroscopic (GC-MS/MS) analysis.

Biochem/physiol Actions

Cyamemazine belongs to the class of phenothiazine drugs. It is known to treat severe depression, schizophrenia and bipolar disorder.
Cyamemazine is a potent antagonist of 5-HT2C and 5-HT3 receptors with antipsychotic and anxiolytic properties.

Recombinant human liver microsomal enzymes of the cytochrome P450 family (CYP1A2, CYP2A6, CYP3A4, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1) were used to determine the metabolic fate of the antipsychotic anxiolytic agent cyamemazine. An LC/MS-MS tandem methodology was developed specifically for

Cyamemazine (Tercian®) is an antipsychotic agent blocking central dopamine D(2) receptors, which induces few extrapyramidal adverse effects, due to a potent antagonistic action at serotonin 5-HT(2A) receptors. In vitro studies showed that the desmethyl metabolite of cyamemazine (N-desmethyl cyamemazine) has

Several studies have suggested that the antipsychotic compound, cyamemazine, possesses anxiolytic properties in humans. The original pharmacological profile of cyamemazine (D(2), 5-HT(2A), 5-HT(2C), and 5-HT(3) receptor antagonist), which was established by binding, microdialysis and behavioral studies, is consistent with these
