  • Patent number: 9802897
    Abstract: An amidopyridinol derivative or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition including the amidopyridinol derivative as an active component represented by Chemical Formula 1 or a pharmaceutically acceptable salt thereof have an antiangiogenic effect in a chorioallantoic membrane model, and thus are useful as an agent for preventing or treating diseases associated with angiogenesis, and also have a colitis-inhibitory effect in a model of inflammatory bowel diseases, and thus are useful as an agent for preventing or treating inflammatory bowel diseases. Upon inoculation of lung cancer cells in a chorioallantoic membrane model, the amidopyridinol derivative of Chemical Formula 1 or the pharmaceutically acceptable salt thereof inhibits angiogenesis and tumor growth that are caused by tumorigenesis, and also inhibits the activity of cathepsin S that plays an important role in metastasis and invasion of cancer, and thus is useful as an inhibitor of cancer growth and metastasis.

  • Patent number: 9505757
    Abstract: Disclosed is a pharmaceutical composition including a bicyclic pyridinol derivative as an active ingredient for preventing or treating diseases caused by angiogenesis. The bicyclic pyridinol derivative expressed by Chemical Formula 1 can be effectively used as a drug for preventing and treating diseases caused by angiogenesis since it inhibits neovascularization in a chorioallantoic membrane model.
