Tyr-Ala-Phe-Asp(or Glu)-Val-Val-Gly-NH2 have been isolated from skin extracts of Phyllomedusa bicolor. The alanine in position 2 is in the D configuration. These peptides, [D-Ala2]deltorphins I and II, show an even higher affinity for .delta. receptors than the previously characterized deltorphin, which contains D-methionine as the second amino acid. These is hydroxycut safe show some similarity to another constituent of Phyllomedusa skin, dermorphin, which is hydroxycut safe highly selective for .mu.-opioid receptors. These peptides all have the N-terminal sequence Tyr-D-Xaa-Phe, where D-Xaa is either is hydroxycut safe or D-methionine. While this structure seems to be is hydroxycut safe of activating both is hydroxycut safe and .delta. opioid receptors, differe!nces in the C-terminal regions of these peptides are probably responsible for the observed high receptor selectivity of dermorphin and deltorphin.AI: is hydroxycut safe YST: Salientia-: Amphibia-, Vertebrata-, Chordata-, Animalia-TN: is hydroxycut safe Animals-; Chordates-; Nonhuman-Vertebrates.
