Background:

Deltorphin C is a peptide agonist of δ-opioid receptors (K_i= 0.15 nM) that has been found inPhyllomedusa bicolor.¹It is selective for δ-opioid receptors over µ- and ?-opioid receptors. It induces δ-opioid receptor translocation from large dense-core vesicles to the cell surface and induces calcitonin gene-related peptide (CGRP) release in isolated mouse dorsal root ganglion (DRG) cells when used at concentrations of 0.1 and 1 µM, respectively, effects that can be blocked with the δ-opioid receptor antagonist naltrindole .²Intrathecal administration of deltorphin C (0.15, 1.5, and 15 µg/animal) increases latency to withdraw in the paw pressure and tail-flick tests in rats.³
