Zotepine

[Description]:

Zotepine, an antipsychotic agent, is a potent antagonist of 5-HT2A, 5-HT2C, Histamine H1, α1-adrenergic and Dopamine D2 receptors, with Kds of 2.6 nM, 3.2 nM, 3.3 nM, 7.3 nM and 8 nM, respectively. Zotepine exhibits antidepressive and anxiolytic effects in vivo[1][2].

[In Vitro]

Zotepine shows multiple antagonistic profiles with strong affinities to α1-adrenergic, α2-adrenergic, Dopamine D2, Histamine H1, Muscarinic, 5-HT1A, 5-HT1D, 5-HT2A, and 5-HT2C receptors, with Kds of 7.3, 180, 8, 3.3, 330, 280, 80, 2.6, 3.2 nM, respectively[1].

[In Vivo]

Zotepine (1-3 mg/kg; a single i.p.) dose-dependently increases noradrenaline, dopamine, GABA, and glutamate release without affecting 5-HT levels in the medial prefrontal cortex of rats[2]. Animal Model: Male Sprague-Dawley rats (250-300 g)[1] Dosage: 1, 3 mg/kg Administration: A single i.p. Result: Increased noradrenaline, dopamine, GABA, and glutamate release without affecting 5-HT levels in the medial prefrontal cortex. Increased neuronal firing frequencies in the VTA, DRN, LC and MTN in a dose-dependent manner.
