摘要: Disclosed is a glucagon-like peptide-1 (GLP-1) analogue which is obtained by ameliorating a highly antigenic GLP-1 analogue so that the GLP-1 analogue has reduced antigenicity without being lowered in the blood glucose suppressing activity. Specifically disclosed is a glycosylated form of an antigenic GLP-1 analogue, which has GLP-1 activity and is obtained by substituting at least one amino acid of an antigenic GLP-1 analogue with a glycosylated amino acid.

摘要: Oligosaccharide chain added GLP-1 peptides are more stable in blood and more active in controlling blood-sugar levels than GLP-1 peptides without added oligosaccharides. Oligosaccharide chain added GLP-1 peptides having GLP-1 activity include at least one or at least two amino acids each substituted with an oligosaccharide chain added amino acid in GLP-1; a peptide having the amino acid sequence of GLP-1 with deletion, substitution or addition of one or several amino acids; or a GLP-1 analog. Oligosaccharide chain added GLP-1 peptides with at least one amino acid substituted with an oligosaccharide chain added amino acid include an oligosaccharide chain with oligo hyaluronic acid. Oligosaccharide chain added amino acids include oligosaccharide chains attached to amino acids via linkers.

摘要: Mutant polypeptides of the present invention contain an Fc region in which a cysteine residue is substituted for the second amino acid from the glycosylation site to the N terminal side in the Fc region. The Fc region is preferably a human IgG Fc region. The mutant polypeptides of the present invention may also contain an N-linked sugar chain at the glycosylation site in Fc region. Furthermore, a polypeptide domain other than the Fc region of the mutant polypeptides of the present invention may be a polypeptide molecule that recognizes a human cell surface molecule.
