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)
体外研究
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.
体内研究
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. 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withdrawal induced anxiety-related behavior, somatic signs, and CPA, and increased hotplate latency in nicotine withdrawn mice following pre-treatment.
