Teduglutide is a glucagon-like peptide-2 (GLP-2) analogue. It is made up of 33 amino acids and is manufactured using a strain of Escherichia coli modified by recombinant DNA technology.Teduglutide differs from GLP-2 by one amino acid (alanine is substituted by glycine). The significance of this substitution is that teduglutide is longer acting than endogenous GLP-2 as it is more resistant to proteolysis from dipeptidyl peptidase-4.
 

Teduglutide was approved in August 2012 by the European Commission and in December 2012 by the US FDA for the treatment of adults with short bowel syndrome (SBS) who are dependent on parenteral nutrition (PN). Teduglutide (also known as ALX-0600) is a GLP-2 analogue in which glycine has been substituted for alanine at position 2 from the N-terminus, thereby conferring resistance to degradation by DPP-4. Teduglutide has similar binding affinity, agonist potency, and agonist efficacy as GLP-2 in assays with the rat GLP-2 receptor. Administration of teduglutide to rats gave a significant increase in small intestine weight and an increase in the height of intestinal villi. Teduglutide was prepared by solid-phase peptide synthesis.
