Dermorphin is a hepta-peptide first isolated from the skin of South American frogs belonging to the genus Phyllomedusa. The peptide is a natural opiate that binds as an agonist with high potency and selectivity to mu Opioid receptors. Dermorphin is about 30-40 times more potent than morphine but less likely to produce drug tolerance and addiction. The amino acid sequence of demorphin is H-Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH2
