Summary

DPDPE ([D-Pen2,D-Pen5]enkephalin) is a synthetic, highly selective delta-opioid receptor agonist used primarily in preclinical research to study analgesia, mood modulation, and opioid receptor pharmacology.

Mechanism of Action

Selective agonist of the delta-opioid receptor (DOR), coupling to Gi/o proteins to inhibit adenylate cyclase and modulate neuronal signaling
