Exendin-4 (3-39) is a truncated peptide variant of Exendin-4, missing the initial two amino acids, and serves as a potent agonist for the Glucagon-like peptide-1 receptor (GLP-1r) . This compound, along with Exendin-4, is utilized in the study of diabetes and hypothalamic-pituitary-adrenal (HPA) axis disorders [1] [2].
