Application

N-Desmethylclozapine has been used as standard to quantify the clozapine plasma levels in treatment-refractory Chinese schizophrenic patients.

Biochem/physiol Actions

N-Desmethylclozapine serves as an agonist to muscarinic acetylcholine receptors, and is known to exert its antipsychotic action. It blocks synaptic transmission by antagonizing synaptic GABA (γ-aminobutyric acid) receptors.
Major metabolite of clozapine; potent 5-HT2 serotonin receptor antagonist and a ligand for the cloned 5-HT6 and 5-HT7 serotonin receptors. Also an allosteric potentiator of M1 muscarinic receptors.

The molecular and neuronal substrates conferring on clozapine its unique and superior efficacy in the treatment of schizophrenia remain elusive. The interaction of clozapine with many G protein-coupled receptors is well documented but less is known about its biologically active

There is increasing evidence that environmental, rather than genetic, factors are the major causes of most chronic diseases. By measuring entire classes of chemicals in archived biospecimens, exposome-wide association studies (EWAS) are being conducted to investigate associations between a myriad

A fully automated method for determination of clozapine and desmethylclozapine in human serum using high-performance liquid chromatography was developed. On-line solid-phase extraction was performed on an exchangeable cyanopropyl cartridge. The analytes were eluted with a methanol-ammonium acetate buffer mobile phase

Clozapine is restricted to use in patients with treatment-refractory schizophrenia due to the risk of a serious drop in absolute neutrophil granulocyte count (ANC). The formation of reactive, unstable metabolites (adducts) has been suggested as a mechanism of clozapine-induced granulocyte
