CAS No. : 27367-90-4
MCE 国际站:Niaprazine
产品活性:Niaprazine 是一种组胺 H1 受体 (histamine H1-receptor) 拮抗剂。Niaprazine 具有抗组胺和抗血清素活性,并可用于睡眠障碍的研究。
研究领域:GPCR/G Protein | Neuronal Signaling | Immunology/Inflammation
作用靶点:Histamine Receptor
In Vitro: Niaprazine exhibits a low affinity for the vesicular monoamine transporter and for D2, α2, β, H1 and mAch receptors. Niaprazine, particularly the (+)stereoisomer, has a higher affinity for α1 (Ki = 77 nM) and 5-HT2 (Ki = 25 nM) binding sites, but is poorly recognized by 5-HT1A and 5-HT1B binding sites.
In Vivo: Niaprazine (60 mg/kg; i.p.; once) treatment increases rat brain 5-hydroxyindole acetic acid (5-HIAA) concentrations 30 min after treatment, and reduced them at 3-8 hr after treatment. Niaprazine also produces a short-lasting depletion of rat brain noradrenaline (NA) and dopamine (DA).
