Exendin-3 (9-39) amide

Exendin-3 (9-39) amide is a truncated form of the exendin-4 (48-86) amide (Cay-11096) peptide that acts as a potent competitive antagonist for the glucagon-like peptide 1 receptor (GLP-1R, Kd = 1.7 nM in CHL cells transfected with cloned human GLP-1). It inhibits exendin-3-induced increases in cAMP levels in guinea pig pancreas cells (IC50 = 20 nM). Exendin-3 (9-39) amide administration in the hypothalamus (10 and 100 µg, i.c.v.) reverses GLP-1 inhibition of feeding behavior in rats.Synonyms: Exendin (9-39). Molecular Formula: C149H234N40O47S .
