DPDPE

DPDPE is a selective δ-opioid receptor agonist peptide that inhibits electrically stimulated contraction of mouse vas deferens in vitro and is antinociceptive in vivo. DPDPE is a heterodetic cyclic peptide that is a cyclic enkephalin analogue, having D-penicillaminyl residues located at positions 2 and 5, which form the heterocycle via a disulfide bond. It has a role as a delta-opioid receptor agonist.
