  • the invention further relates to methods of making and using such peptides.
  • Diabetes mellitus is a metabolic disorder in which the ability to utilize glucose is partly or completely lost. About 5% of all people suffer from diabetes and the disorder approaches epidemic proportions. Since the introduction of insulin in the 1920 ' s, continuous efforts have been made to im- prove the treatment of diabetes mellitus.
  • GLP-1 glucagon-like peptide-1
  • Human GLP-1 is a 37 amino acid residue peptide originating from preproglucagon which is synthesized La. in the L-cells in the distal ileum, in the pancreas and in the brain.
  • GLP-1 is an important gut hormone with regulatory function in glucose metabolism and gastrointestinal secretion and metabolism. GLP-1 stimulates insulin secretion in a glucose-dependant manner, stimulates insulin biosynthesis, promotes beta cell rescue, decreases glucagon secretion, gastric emptying and food intake.
  • GLP-1 Human GLP-1 is hydrolysed to GLP-1 (7-37) and GLP-1 (7-36)-amide which are both insulinotropic peptides.

  • Exendin-4 is a 39 amino acid residue peptide isolated from the venom of Heloderma suspectum, and this peptide shares 52% homology with GLP-1 (7-37) in the overlapping region.
  • Exendin-4 is a potent GLP-1 receptor agonist which has been shown to stimulate insulin release and ensuing lowering of the blood glucose level when injected into dogs.
