生物活性

Aticaprant (CERC-501) is a potent and centrally-penetrant kappa opioid receptor antagonist with a Ki of 0.807 nM.

IC50 & Target

Ki: 0.807 nM (kappa opioid)[1]

体外研究
(In Vitro)

Aticaprant (CERC-501) binds with high affinity to the human kappa opioid receptor with a 30-fold higher affinity over the human mu opioid receptor and 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, including monoaminergic, muscarinic, cholinergic, and adrenergic receptors or ion channel/transporter binding targets or the central benzodiazepine binding site[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Aticaprant (CERC-501) has a rapid absorption (tmax=1-2 h) and good oral bioavailability (F=25%). Oral Aticaprant (CERC-501) administration selectively and potently occupies central kappa opioid receptors (ED50=0.33 mg/kg), without evidence of mu or delta receptor occupancy. LY2456302 potently blocks kappa-agonist-mediated analgesia and disruption of prepulse inhibition, without affecting mu-agonist-mediated effects at doses >30-fold higher. Aticaprant (CERC-501) produces antidepressant-like effects in the mouse forced swim test and enhances the effects of imipramine and citalopram. Aticaprant (CERC-501) reduces ethanol self-administration in alcohol-preferring rats[1]. Aticaprant (CERC-501) alleviates the nicotine withdrawal syndrome, as evidenced by decreased expression of nicotine withdrawal induced anxiety-related behavior, somatic signs, and CPA, and increased hotplate latency in nicotine withdrawn mice following pre-treatment[2].

Animal Administration
[1]

Rats: Three male cannulated rats are administered a single 1 mg/kg intravenous (IV) and 10 mg/kg oral (PO) dose of Aticaprant (CERC-501) 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)[1].

Mice: Male mice are administered a single 10 mg/kg PO dose of Aticaprant (CERC-501) to determine the pharmacokinetic parameters. Plasma samples are collected at 0.5, 1, 2, 4, 8, and 24 h post-dose and analyzed by LCeMS/MS to determine the concentrations of Aticaprant (CERC-501). The plasma and brain binding of Aticaprant (CERC-501) is determined by equilibrium dialysis at 1 μM[1].
