Deltorphin II is a peptide agonist of ?2-opioid receptors.{25533,37715} It is selective for ?-opioid receptors over ?- and ?-opioid receptors in radioligand bindings assays (Kis = 0.0033, >1, and >1 µM, respectively) and induces [35S]GTP?S binding in mouse brain membrane preparations (EC50 = 0.034 µM). Deltorphin II (0.12 mg/kg) decreases the infarction zone:risk zone ratio in a rat model of myocardial ischemia-reperfusion injury induced by coronary occlusion, an effect that can be reversed by the ?2-opioid receptor antagonist naltriben but not the ?1-opioid receptor antagonist BNTX.{62411} Intrathecal administration of deltorphin II (15 µg/animal) increases latency to withdraw in the paw pressure and tail-flick tests in rats.{46878}
