Abstract: The present invention relates to a pharmaceutical composition for the prevention or treatment of non-alcoholic fatty liver disease including a long-acting GLP-1/glucagon receptor dual agonist, and a method for preventing or treatment of non-alcoholic fatty liver disease including administering the composition. The composition of the present invention either has no side effect of weight gain or reduces the side effect of weight gain, which is a side-effect of conventional therapeutic agents for non-alcoholic fatty liver disease, and reduces the amount of administrations of a long-acting GLP-1/glucagon receptor dual agonist, thus greatly improving patient's convenience. In addition, the long-acting GLP-1/glucagon receptor dual agonist of the present invention improves in vivo sustainability and stability.

Abstract: A composition for preventing or treating diabetes mellitus includes insulin and a GLP-1/glucagon dual agonist. The composition can inhibit the weight gain and reduce the danger of hypoglycemia due to the administration of insulin, lower the administration dose and greatly improve the compliance of drugs through a combined administration of a long-acting insulin conjugate and a long-acting GLP-1/glucagon dual agonist conjugate. In addition, the long-acting insulin conjugate and the long-acting GLP-1/glucagon dual agonist conjugate can improve the in vivo sustainability and stability because an insulin and a GLP-1/glucagon dual agonist are linked to the immunoglobulin Fc region via a non-peptidyl linker. A method for preventing or treat diabetes mellitus includes administration of the insulin and a GLP-1/glucagon dual agonist.

Abstract: An insulin analog has a reduced insulin titer and a reduced insulin receptor binding affinity compared to the native form for the purpose of increasing the blood half-life of insulin. A conjugate is prepared by linking the insulin analog and a carrier. A long-acting formulation includes the conjugate.

Abstract: 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.

Abstract: The present invention relates to immunoglobulin Fc variants having an increased binding affinity for FcRn, which is characterized by including one or more amino acid modifications selected from the group consisting of 307S, 308F, 380S, 380A, 428L, 429K, 430S, 433K and 434S (this numbering is according to the EU index) in the constant region of a native immunoglobulin Fc fragment. Owing to the high binding affinity for FcRn, the immunoglobulin Fc variants according to the present invention show more prolonged in vivo half-life, and thus can be used for the preparation of a long-acting formulation of protein drugs.
