Met-Enkephalinamide is a peptide opioid receptor agonist and derivative of Met-enkephalin .1,2 It binds to opioid receptors in rat cerebellum homogenates (IC50 = 0.2 µM) and reduces the twitch height in electrically stimulated isolated guinea pig ileum and isolated mouse vas deferens. Met-Enkephalinamide (300 µg/animal) induces analgesia in the hot plate and tail-flick tests in rats, effects that can be reversed by administration of the opioid receptor antagonist naloxone.3
