Product Information:
CERC-501(LY-2456302), also known as JNJ-67953964, LY-2456302 and CERC-501, is a potent, selective, short-acting antagonist of the κ-opioid receptor (KOR) (Ki = 0.81 nM vs. 24.0 nM and 155 nM for the μ-opioid receptor (MOR) and δ-opioid receptor (DOR). Aticaprant is under development for the treatment of major depressive disorder and substance use disorders including alcoholism, nicotine addiction, and illicit drug dependence. Aticaprant has been found to dose-dependently block fentanyl-induced miosis at 25 mg and 60 mg in humans (with minimal to no blockade at doses of 4 to 10 mg), indicating that the drug significantly occupies and antagonizes the MOR at a dose of at least 25 mg but not of 10 mg or less.

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.
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withdrawal induced anxiety-related behavior, somatic signs, and CPA, and increased hotplate latency in nicotine withdrawn mice following pre-treatment.
