Dermorphin is an opioid peptide originally isolated from the skin of South American frogs (Ph. sauvagei).1 It binds to μ-opioid receptors (Ki = 0.54 nM) and is selective for μ- over δ-opioid receptors in radioligand binding assays (Ki = 929 nM). In vivo, dermorphin (1.9 µmol/kg, i.p.) inhibits noxious stimuli-induced neuronal firing in the nucleus lateralis anterior and ventrobasal complex in rats.2 It inhibits the electrical stimulation-induced C fiber response in rat dorsal horn nociceptive neurons. Dermorphin (10-120 pmol/animal, i.c.v.) delays gastric emptying, inhibits gastric acid secretion, and slows colonic motility in pylorus-ligated rats.
