Product Introduction

Bioactivity
Description
Aticaprant (CERC-501) is a potent and centrally-penetrant antagonist of the kappa-opioid receptor (Ki: 0.807 nM).[2]
Targets&IC50
κ opioid:0.807 nM (Ki)
In vitro
Aticaprant(CERC-501) binds with a high affinity to the human kappa opioid receptor with a 30-fold higher affinity over the human mu-opioid receptor and a 190-fold higher affinity over the human delta-opioid receptor. Aticaprant(CERC-501) shows no appreciable affinity for several non-opioid cell surface G-protein-coupled receptor targets [1].
In vivo
METHODS: Mice were given Aticaprant(CERC-501) (0.1 to 3 mg/kg, intraperitoneal injection) 30 minutes before the alcohol deprivation effect (ADE) test and naltrexone (0.3 or 1 mg/kg, intraperitoneal injection) 10 minutes before the test to observe the effect of aticaprant on the ADE effect.
RESULTS 0.3 mg/kg of Aticaprant(CERC-501) and 1 mg/kg of naltrexone reduced the ADE alcohol intake of mice at 4 hours. [1]
Animal Research
Three male cannulated rats are administered a single 1 mg/kg intravenous (IV) and 10 mg/kg oral (PO) dose of Aticaprant to determine the pharmacokinetic parameters. Plasma samples are collected at 0.08 (IV only), 0.25, 0.5, 1, 2, 4, 8, 12 and 24 h post-dose and analyzed by liquid chromatography coupled to tandem mass spectral detection to determine the concentrations of Aticaprant (CERC-501). Male mice are administered a single 10 mg/kg PO dose of Aticaprant to determine the pharmacokinetic parameters. Plasma samples are collected at 0.5, 1, 2, 4, 8, and 24 h post-dose and analyzed by LCMS/MS to determine the concentrations of Aticaprant. The plasma and brain binding of Aticaprant is determined by equilibrium dialysis at 1 μM [1].

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
