Exenatide Acetate CAS:141732-76-5

Exendin-4 (exenatide), a 39-amino acid peptide originally isolated from the salivary glands of the Gila monster (Heloderma suspectum), differs from exendin-3 only in two positions close to the N-terminus. Application of exenatide causes an increase in acinar CAMP without stimulating amylase release. As an incretin mimetic, exenatide acts as agonist of the glucagon-like peptide-1 (GLP-1) receptor. As GLP-1, though with prolonged activity, exenatide augments the postprandial production of insulin and suppresses secretion of glucagon. For this reason, exenatide has found use as a medication of diabetes II.

Exenatide Acetate is a polypeptide composed of 39 amino acids.It is a long-acting glucagon-like peptide-1 receptor agonist with an IC50 value of 3.22 NM.

Exenatide is a synthetic version of Exendin-4, an insulin secretagogue with glucoregulatory effects. It displays biological properties similar to human Glucagon-Like Peptide-1 (GLP-1), a regulator of glucose metabolism and insulin secretion. Exenatide enhances glucose-dependent insulin secretion by the pancreatic beta-cell, suppresses inappropriately elevated glucagon secretion, and slows gastric emptying.
