    • An insulinotropic peptide conjugate is provided to maintain the in-vivo activity relatively high and show remarkably increased blood half-life, thereby being usefully used for developing long acting formulations of various peptide drugs. An insulinotropic peptide conjugate comprises an insulinotropic peptide and an immunoglobulin Fc region, which are linked by a non-peptidyl polymer, wherein the non-peptidyl polymer is selected from the group consisting of polyethylene glycol, polypropylene glycol, copolymers of ethylene glycol and propylene glycol, polyoxyethylated polyols, polyvinyl alcohol, polysaccharides, dextran, polyvinyl ethyl ether, biodegradable polymers, lipid polymers, chitins, hyaluronic acid, and combinations thereof, and wherein one end of the non-peptidyl polymer is linked to an amino acid residue other than the N-terminus of the insulinotropic peptide. An insulinotropic peptide derivative is represented by a formula(1) of R1-X-Y-Z-R2, wherein R1 is selected from the group consisting of histidine, des-amino-histidyl, N-dimethyl-histidyl, beta-hydroxy imidazopropyl and 4-imidazoacetyl; R2 is selected from the group consisting of NH2, OH and Lys; X is selected from the group consisting of GIy-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Leu-Ser-RS-Gln-Met-Glu-Glu-Glu-Ala-Val-Arg- Leu-Phe-Ile-Glu-Trp-Leu-R4-Asn-Gly-Gly-Pro-Ser-Ser-Gly-Ala-Pro-Pro-Pro-Ser, GIy-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Leu-Ser-R3-Gln-Met-Glu-Glu-Glu-Ala-Val-Arg-Leu-Phe-Ile-Glu-Trp-Leu-R4-Asn-Gly-Gly, and Ser-Asp-Gly-Thr-Phe-Thr-Ser-Asp-Leu-Ser-RS-Gln-Met-Glu-Glu-Glu-Ala-Val-Arg- Leu-Phe-Ile-Glu-Trp-Leu-R4-Asn-Gly-Gly-Pro-Ser-Ser-Gly-Ala-Pro-Pro-Pro-Ser; R3 is selected from the group consisting of Lys, Ser and Arg; R4 is selected from the group consisting of Lys, Ser and Arg; Y is polyethylene glycol, polypropylene glycol, copolymers of ethylene glycol and propylene glycol, polyoxyethylated polyols, polyvinyl alcohol, polysaccharides, dextran, polyvinyl ethyl ether, biodegradable polymers, lipid polymers, chitins, hyaluronic acid, and combinations thereof; and Z is an immunoglobulin Fc region. A pharmaceutical composition for treating diabetes, obesity, acute coronary syndrome, or polycystic ovary syndrome comprises the peptide conjugate. Further, the insulinotropic peptide is selected from GLP-1, exendin-3, exendin-4 or agonist there, derivative, fragment, variant and a mixture thereof.

    • Methods are provided for reducing serum proinsulin levels, lessening post-prandial pancreatic stress, and reducing risk factors for atherosclerosis in subjects with diabetes mellitus, type 2. The method includes administration of insulin in a manner that mimics the meal-related first phase insulin response, using a dose sufficient to reduce serum levels of proinsulin. In some embodiments of the method insulin administration is commenced early in the course of the disease. Mimicking first phase kinetics, peak serum insulin levels can be reached within about 18 minutes of administration. In increasingly preferred embodiments peak serum insulin levels can be reached within about 15, 12, or 10 minutes of administration. Serum insulin levels return to baseline within about two hours of administration.
