CJ-15208 is a potent and selective κ-opioid receptor antagonist from a fungus, Ctenomyces serratus ATCC15502. CJ-15208 was a selective binding inhibitor for the kappa opioid receptor: 47 nM (IC50) for kappa, 260 nM for mu, and 2,600 nM for delta. In the electrically-stimulated twitch response assay of rabbit vas deferens I recovered the suppression by a kappa agonist asimadoline with an ED50 of 1.3 microM, indicating that it is a kappa antagonist.
