| Xenopsin 2TFA | Xenopsin 2TFA is a neurotensin-like octapeptide previously isolated from amphibian skin. Synonyms: H-Pyr-Gly-Lys-Arg-Pro-Trp-Ile-Leu-OH.2TFA; L-pyroglutamyl-glycyl-L-lysyl-L-arginyl-L-prolyl-L-tryptophyl-L-isoleucyl-L-leucine trifluoroacetic acid; 5-Oxo-L-prolylglycyl-L-lysyl-L-arginyl-L-prolyl-L-tryptophyl-L-isoleucyl-L-leucine trifluoroacetate; Xenopsin trifluoroacetate; L-Leucine, N-[N-[N-[1-[N2-[N2-[N-(5-oxo-L-prolyl)glycyl]-L-lysyl]-L-arginyl]-L-prolyl]-L-tryptophyl]-L-isoleucyl]-, trifluoroacetate (1:2); Xenopsin (Xenopus amieti) trifluoroacetate. Grades: ≥95%. Molecular formula: C51H75F6N13O14. Mole weight: 1208.23. | |
| Xenopsin precursor fragment | Xenopsin precursor fragment is an antibacterial peptide isolated from Xenopus laevis. It has activity against gram-positive bacteria, gram-negative bacteria and fungi. Synonyms: XPF; Gly-Trp-Ala-Ser-Lys-Ile-Gly-Gln-Thr-Leu-Gly-Lys-Ile-Ala-Lys-Val-Gly-Leu-Lys-Glu-Leu-Ile-Gln-Pro-Lys. Grades: >96%. Molecular formula: C123H211N33O32. Mole weight: 2664.23. | |
| Xenin | Xenin, a 25-amino acid peptide initially isolated from human gastric mucosa, has 6 C-terminal amino acids in common with amphibian xenopsin. Xenin may stimulate the enzyme release from the exocrine pancreas. Synonyms: Xenin-25; L-Methionyl-L-leucyl-L-threonyl-L-lysyl-L-phenylalanyl-L-α-glutamyl-L-threonyl-L-lysyl-L-seryl-L-alanyl-L-arginyl-L-valyl-L-lysylglycyl-L-leucyl-L-seryl-L-phenylalanyl-L-histidyl-L-prolyl-L-lysyl-L-arginyl-L-prolyl-L-tryptophyl-L-isoleucyl-L-leucine; Human Xenin. CAS No. 144092-28-4. Molecular formula: C139H224N38O32S. Mole weight: 2971.57. | |
| Xenin 8 | Xenin 8, a C-terminal fragment of xenin, can modulate pancreatic insulin and glucagon secretion/effects. Xenin 8 stimulates basal and arginine-induced insulin secretion and potentiates the insulin response to glucose (EC50 = 0.16 nM). Synonyms: Xenopsin-related peptide 1; XP-1. CAS No. 117442-28-1. Molecular formula: C51H79N15O9. Mole weight: 1046.28. | |
