  • Patent number: 10550168
    Abstract: Disclosed are a composition for preventing or treating diabetes, disbesity or diabetic complications, containing an oxyntomodulin analog as an active ingredient and a method for treating diabetes, diabesity or diabetic complications, including administering a pharmaceutically effective amount of an oxyntomodulin analog to a subject. The oxyntomodulin analog shows a greater activity to activate a GLP-1 receptor and a glucagon receptor, than native oxyntomodulin. The oxyntomodulin analog induces an expansion of beta-cells and increases insulin secretion, thereby reducing blood glucose levels that were increased due to a high-calorie and high-fat diet. The oxyntomodulin analog induces decreases in a body weight and appetite to improve insulin sensitivity and is useful in maintaining normal blood glucose levels.

  • Patent number: 10493132
    Abstract: 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.
