  • Publication number: 20220106307
    Abstract: The present invention relates to a pyrrolo-pyridine derivative compound, a method for preparing the same, and a pharmaceutical composition containing the same as an active ingredient for the prevention or treatment of protein kinase-related diseases. A compound represented by chemical formula 1, an optical isomer thereof, or a pharmaceutically acceptable salt thereof, according to the present invention, has excellent inhibitory activity against various protein kinases including DYRK1A, and therefore, the pharmaceutical composition containing the same as an active ingredient can be favorably used in the treatment or prevention of protein kinase-related diseases. Particularly, the pharmaceutical composition can be effectively used in the prevention, treatment, or alleviation of Alzheimer's disease, dementia, or Alzheimer's dementia.

  • Patent number: 10870647
    Abstract: The present invention relates to a novel imidazopyridine derivative, a method for preparing the same, and a pharmaceutical composition containing the same as an active ingredient for preventing or treating cancer. The novel imidazopyridine derivative according to the present invention, a stereoisomer thereof and a pharmaceutically acceptable salt thereof can effectively inhibit cancer-related kinases, are excellent in inhibiting proliferation of cancer cells in a cancer cell line, and effectively inhibit proliferation of cancer cells (cancer cell apoptosis) in a cancer cell heterograft model, and thus can be useful as a pharmaceutical composition containing the same as an active ingredient for preventing or treating cancer.
