半岛bd体育手机客户端 描述

Deltorphin II is a peptide agonist of δ2-opioid receptors.1,2It is selective for δ-opioid receptors over μ- and κ-opioid receptors in radioligand bindings assays (Kis = 0.0033, >1, and >1 ?M, respectively) and induces [35S]GTPγS binding in mouse brain membrane preparations (EC50= 0.034 ?M). 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 δ2-opioid receptor antagonist naltriben but not the δ1-opioid receptor antagonist BNTX.3Intrathecal administration of deltorphin II (15 ?g/animal) increases latency to withdraw in the paw pressure and tail-flick tests in rats.4
