  • Patent number: 11713344
    Abstract: A novel peptide analog of acylated oxyntomodulin and its uses are disclosed. A pharmaceutical composition containing the novel peptide analog is useful and effective for preventing and treating obesity or overweightness, or diabetes accompanied by obesity and overweightness. The peptide analog and a composition containing the peptide analog are superior to those of wild-type oxyntomodulin in dual agonism on GLP-1 and glucagon receptors and longer in vivo half-life. A pharmaceutical composition containing the peptide analog is effective in the treatment of metabolic diseases such as obesity and diabetes mellitus.

  • Publication number: 20230220035
    Abstract: A novel long-acting acylated oxyntomodulin peptide analogue having dual agonism on GLP-1 and glucagon receptors (dual GLP-1R/GlucagonR agonism) and a pharmaceutical composition including the same are disclosed. The novel long-acting acylated oxyntomodulin peptide analogue and the composition are useful for the prevention and treatment of obesity and overweight, or non-insulin-dependent diabetes accompanied by obesity and overweight. The acylated oxyntomodulin peptide analog has dual agonism for GLP-1/glucagon receptors and has an excellent increased in vivo half-life, and the pharmaceutical composition containing the same is useful for the treatment of metabolic diseases such as obesity and diabetes.
