Clozapine N-oxide (Synonyms: 氯dan平N-氧化物)
Clozapine N-oxide 是一種 Clozapine 的主要代謝產(chǎn)物,也是一種人毒蕈堿設(shè)計(jì)受體 (DREADDs) 激動(dòng)劑。Clozapine N-oxide 可ji活 DREADD 受體 hM3Dq 和 hM4Di。Clozapine N-oxide 可以穿過血腦屏障。Clozapine 是一種有效的多巴胺拮抗劑,也一種是有效的選擇性毒蕈堿 M4 受體 (muscarinic M4 receptor) (EC50 為 11 nM) 激動(dòng)劑。
生物活性
Clozapine N-oxide is a major metabolite of Clozapine and a human muscarinic designer receptors (DREADDs) agonist. Clozapine N-oxide activates the DREADD receptor hM3Dq and hM4Di. Clozapine N-oxide can cross the blood-brain barrier[1][2][3][4]. Clozapine is a potent dopamine antagonist and also a potent and selective muscarinic M4 receptor (EC50=11 nM) agonist[5][6].
IC50 & Target
Human muscarinic designer receptors (DREADDs)[1]
體外研究(In Vitro)
Clozapine N-oxide (CNO) can bind to non-DREADD receptors at concentrations required for DREADD activation, and undergoes reverse-metabolism to its parent compound clozapine, an atypical antipsychotic that acts at a variety of pharmacological targets and produces numerous physiological and behavioral effects[2].
體內(nèi)研究(In Vivo)
After a single intraperitoneal (i.p.) injection of Clozapine N-oxide (1 mg/kg) into mice, Clozapine N-oxide (CNO) plasma levels peak at 15 min and are very low after 2 h. Despite the short plasma half-life of CNO in mice, the biological effects that have been described after acute treatment of DREADD-expressing experimental animals are usually much longer (6-10 h)[1].
