摘要:
The present invention relates to an albumin-free liquid formulation comprising a long-lasting oxyntomodulin conjugate in which an oxyntomodulin peptide comprising a derivative, variant, precursor or fragment of oxyntomodulin is linked to an immunoglobulin Fc region, which can increase the duration of physiological activity of the long-lasting oxyntomodulin conjugate and maintain the invivo stability thereof for an extended period of time, as compared to native oxyntomodulin, as well as a method for preparing the liquid formulation. The liquid formulation comprises a buffer, a sugar alcohol and a nonionic surfactant and does not contain a human serum albumin and factors that are potentially harmful to the human body, and thus is not susceptible to viral infection. In addition, the oxyntomodulin conjugate of the invention comprises oxyntomodulin linked to an immunoglobulin Fc region, and thus has a large molecular weight, prolonged physiological activity, and excellent storage stability, compared to native oxyntomodulin.

The present invention relates to an insulin analog that 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 prepared by linking the insulin analog and a carrier, a long-acting formulation including the conjugate, and a method for preparing the conjugate.
摘要:
The present invention relates to a method for preparing a conjugate by linking a physiologically active polypeptide, a non-peptidyl polymer linker, and an immunoglobulin constant region via a covalent bond. More particularly, the present invention relates to a method for efficiently preparing the physiologically active polypeptide conjugate, in which a salt is used in a coupling reaction to improve the problem of low production yield during preparation of the physiologically active polypeptide conjugate. The complex of physiologically active polypeptide - non-peptidyl polymer - immunoglobulin constant region can be produced with high purity and yield by the preparation method of the present invention. Due to the method for preparing the physiologically active polypeptide conjugate, production costs can be reduced. Therefore, the method can be used to develop long-acting formulations of physiologically active polypeptides, which have improved industrial applicability and drug regulation compliance.

The present invention relates to a composition for preventing or treating hyperlipidemia, fatty liver disease or arteriosclerosis, comprising an oxyntomodulin derivative as an active ingredient. The oxyntomodulin derivative has a high ability to activate GLP-1 receptor and glucagon receptor compared to native oxyntomodulin and has the effects of reducing the blood total cholesterol, low-density cholesterol and triglyceride levels that were increased by high-fat diet, and increasing high-density cholesterol levels and the high-density cholesterol/low-density cholesterol ratio. Thus, the oxyntomodulin derivative can be effectively used for the treatment of hyperlipidemia and related diseases.
