Xenopsin(2TFA) is a neurotensin-like octapeptide previously isolated from amphibian skin.

Dermorphin Analog, an analog of Dermorphin, is a natural heptapeptide μ-opioid receptor agonist found in amphibian skin. The dermorphin-derived peptide [Dmt1] Dermorphin Analog labels μ-opioid receptors with high affinity and selectivity in receptor binding assays.

Xenin is a 25 amino acid peptide that has been identified in human gastric mucosa in the search for a counterpart to the amphibian octapeptide xenopsin.

Aurein 1.2, an amphibian-derived peptide, exhibits both antibiotic and anticancer properties [1].

Amphibian bombesin-like peptide

Dermorphin is agonist of μ-opioid receptor (MOR) agonist.

Xenopsin-Related Peptide 2 (XP-2), an avian analog of amphibian Xenopsin, exhibits efficacy in histamine release from isolated rat mast cells comparable to synthetic Bradykinin [1].

Granuliberin R, a dodecapeptide derived from the skin of the frog Rana rugosa, is a novel amphibian-origin mast cell degranulating peptide. It has the ability to target rat peritoneal mast cells, prompting them to release granules and histamine [1] [2].

Dermorphin TFA is a new class of opioids-like peptides

Alytesin acetate is an amphibian bombesin-like peptide.

Xenopsin (Xenopsin(2TFA))(2TFA) is a neurotensin-like octapeptide previously isolated from amphibian skin.

Litorin acetate, an amphibian bombesin peptide derivative, is an bombesin receptor agonist. It stimulates the contraction of smooth muscle, stimulates gastrin, gastric acid, and pancreatic secretion, and suppresses the nutriment in vivo.
