xenin

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.

Xenin 8 acetate is a biologically active fragment of Xenin in the neurotensin/xenopsin family. Xenin 8 acetate augments Arginine-induced insulin release (by 40%) and potentiates the glucagon responses to both Arginine (by 60%), Carbachol (by 50%).

neurotensin-like peptide that modulate pancreatic insulin and glucagon secretion/effects

Xenin-8 TFA, a biologically active C-terminal octapeptide derived from the 25-amino acid peptide Xenin of the neurotensin xenopsin family, enhances basal insulin secretion and amplifies glucose-stimulated insulin release in a dose-dependent manner (EC50=0.16 nM) [1].
