CLOZAPINE N-OXIDE Structural

What is CLOZAPINE N-OXIDE?

Description

Clozapine-N-oxide (34233-69-7) is a clozapine?metabolite1?which is pharmacologically inert2. Agonist at human muscarinic designer receptors known as DREADDs, (designer receptors exclusively activated by designer drug).2?May be used to control grafted human pluripotent stem cell-derived neurons engineered to express DREADDs.3,4??Numerous other applications.5,6

Chemical properties

Yellow Solid

The Uses of CLOZAPINE N-OXIDE

Clozapine N-oxide has been used:

  • for the activation of human M4 muscarinic (hM4Di) in primary motor cortex
  • for inducing in vivo chemogenetic manipulation and impairing locomotor activity in Th-cre transgenic mice
  • in behavioral testing in mice and for stimulating (HEK293) cells

The Uses of CLOZAPINE N-OXIDE

A 5-HT2 antagonist. A major metabolite of clozapine that can be monitored by HPLC. Possesses little or no activity towards serotonin receptors

What are the applications of Application

Clozapine N-oxide Methanol Adduct is a major metabolite of clozapine

What are the applications of Application

Clozapine N-oxide is a major metabolite of Clozapine noted to decrease 5-HT2 serotonin receptor density

Definition

ChEBI: Clozapine N-oxide is a dibenzodiazepine.

General Description

Clozapine N-oxide (CNO), inactive from of clozapine drug, activates G-protein-coupled receptors (GPCRs). CNO serves as a synthetic ligand for engineered human muscarinic receptor. It elicits clozapine-like effects upon metabolic conversion. Clozapine conversion to CNO favors its passage through blood-brain barrier.

Biochem/physiol Actions

5-HT2 serotonin receptor antagonist; major metabolite of clopazine that can be monitored by HPLC.

storage

Room temperature (desiccate)
