GLP-2 (rat) (trifluoroacetate salt)

Glucagon-like peptide 2 (GLP-2) is a gut peptide hormone antagonist of the GLP-2 receptor (GLP-2R; Ki = 60 pM).1 It increases cAMP levels in COS cells expressing GLP-2R with an EC50 value of 0.58 nM. GLP-2 is primarily produced by enteroendocrine L cells of the small and large intestine but can also be found in the hypothalamus.1,2 In vivo, GLP-2 (43.75 μg twice per day for 10 days) increases small bowel weight by 50% and increases villus height and crypt cell proliferation in the small intestine in mice.3 GLP-2 (10 μg per animal) reduces two-hour food intake in rats by 37% with no reduction in water intake.2 Secretion of GLP-2 in rats is stimulated by dietary carbohydrates, glucose, dextrin, and oils rich in polyunsaturated or monounsaturated fatty acids.4
