Product Introduction

Bioactivity
Description
Niaprazine is a histamine H1-receptor antagonist exhibiting significant sedative properties.
Targets&IC50
5-HT2:25 nM(Ki), α1-adrenoceptor:77 nM(Ki)
In vitro
Niaprazine demonstrates a low affinity for the vesicular monoamine transporter as well as D2, α2, β, H1, and mAch receptors. Notably, the (+)stereoisomer of Niaprazine shows a significantly higher affinity for α1 (Ki = 77 nM) and 5-HT2 (Ki = 25 nM) binding sites, whereas it is poorly recognized by 5-HT1A and 5-HT1B binding sites[2].
In vivo
Niaprazine (60 mg/kg; i.p.; once) treatment increases rat brain 5-hydroxyindole acetic acid (5-HIAA) concentrations 30 minutes post-treatment but reduces them 3-8 hours after treatment. Niaprazine also temporarily depletes rat brain noradrenaline (NA) and dopamine (DA) levels[3]. Animal Model: Male Sprague-Dawley rats (150-200 g)[3].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
