  • Patent number: 9580399
    Abstract: The present invention relates to a novel geranyl flavonoid derivative with improved water-solubility or a pharmaceutically acceptable salt thereof, a method for preparing the same, and a method for treating cancer using the same. Particularly, the novel geranyl flavonoid derivative of the present invention inhibits the expression of STAT3 target protein by suppressing the phosphorylation of STAT3 (Signal Transducers and Activators of Transcription 3) protein, suggesting that it has cancer cell growth inhibiting effect in various cancer cell lines. Also, the compound of the invention has the effect of reducing the size and weight of a tumor significantly in vivo, so that the geranyl flavonoid derivative or the pharmaceutically acceptable salt thereof can be efficiently used for the treatment of cancer.
    Type: Grant

    Inventors: Byoung-Mog Kwon, Dong Cho Han, Yoon-Jeong Jeon, Joongku Lee, Sangho Choi
  • Patent number: 9486490
    Abstract: The present invention relates to a pharmaceutical composition for preventing and treating cancer which comprises the extracts of Artocarpus altilis fruits, leaves, or stems, or the fractions thereof as active ingredients. The extracts of Artocarpus altilis fruits, leaves, or stems, or the fractions thereof, according to the present invention, suppress the activity of signal transducer and activator of transcription3 (STAT3) which plays an important role in the growth of a cancer cell line and in the immune function of the human body, and can thus be effectively used in the prevention and treatment of cancers such as colorectal cancer, stomach cancer, prostate cancer, breast cancer, renal cancer, liver cancer, brain tumor, lung cancer, uterine cancer, colorectal cancer, bladder cancer, or pancreatic cancer.
