Notes: Naloxone benzoylhydrazone is an antagonist of μ-, κ1-, and δ-opioid receptors (pA2s = 8.82, 7.45, and 7.76, respectively, for the mouse receptors).{69496} It is also an agonist of the κ3-opioid receptor (IC50 = 0.7 nM for the guinea pig receptor). Naloxone benzoylhydrazone (1 µg/animal, i.c.v.) inhibits increases in the latency to tail withdrawal induced by the μ-opioid receptor agonist DAMGO (Item No. 21553) in a hot plate assay in mice.{69497} It increases food intake in rats when intracerebrally administered at doses of 0.1, 1, and 20 µg/animal.{69498}
