Overview

Deltorphin II is a heptapeptide isolated from the skin of South American frogs (Phyllomedusa species), characterized by a D-alanine at position 2 that confers high selectivity for delta-opioid receptors (DOR). It is used as a reference agonist for DOR research, including studies of pain, addiction, anxiety, & cardiac protection. Not for clinical or self-use.
