    摘要: Provided are a glucagon-like peptide-2 (GLP-2) conjugate containing native GLP-2 or its derivative and an immunoglobulin Fc fragment being covalently linked via a non-peptidyl polymer, wherein the native GLP-2 or its derivative has a thiol group introduced at its C-terminal end, and one end of the non-peptidyl polymer is linked to an amino acid residue of the GLP-2 other than the N-terminal amino group thereof; a method for preparing the GLP-2 conjugate; a pharmaceutical composition comprising the same; and a method for treating or preventing intestinal disease, intestinal injury, or gastrosis by using the same. Since the GLP-2 conjugate of the present invention has a remarkably increased binding affinity to a GLP-2 receptor, it shows a prolonged in vivo half-life and an improved in vivo durability and stability.
