    摘要: The present invention relates to a transformant prepared by introducing an expression vector comprising a polynucleotide encoding for a human immunoglobulin Fc fragment into Pichia sp. yeast, a method for producing an immunoglobulin Fc fragment comprising culturing the transformant, and recovering the immunoglobulin Fc fragment from the culture, and an immunoglobulin Fc fragment, prepared by the above method for use as a drug carrier. The transformant is suggested as a solution to the problems associated with the use of E. coli or animal cells as hosts for producing immunoglobulin Fc fragments useful as drug carriers, so that it can find various applications in the effective and economical production of drugs.

    摘要: The present invention relates to a novel glucagon derivative peptide, and a composition for preventing or treating hypoglycemia containing the novel glucagon derivative peptide as an active ingredient. The glucagon derivative according to the present invention has improved physical properties due to the change in isoelectric point (pI) while being capable of maintaining an activity on glucagon receptors, and thus can improve patient compliance when used as a hypoglycemic agent, and is also suitable for administration in combination with other anti-obesity agents. Accordingly, the glucagon derivative according to the present invention can be effectively used for the prevention and treatment of hypoglycemia and obesity.

    摘要: The present invention relates to an insulinotropic peptide derivative with a modified N-terminal charge and a pharmaceutical composition including the same. Specifically, the insulinotropic peptide derivative is characterized in that the N-terminal positive charge of the insulinotropic peptide is modified to a neutral or net negative charge at neutral pH. The insulinotropic peptide derivative according to the present invention is rapidly dissociated from the GLP-1 receptor owing to the above modification in the N-terminal charge, and exhibits enhanced insulinotropic ability and blood glucose-lowering activity compared to the native insulinotropic peptide while maintaining its stability in blood. Accordingly, the insulinotropic peptide derivative of the present invention is very useful for the treatment of type 2 diabetes.
