  • Patent number: 9072698
    Abstract: The present invention relates to a method for screening an anticancer compound and an anticancer compound screened using the method, and more particularly, to a method for screening an anticancer compound, the method comprising: culturing cancer cells expressing the oncogenic protein transmembrane 4 L6 family member 5 (TM4SF5), expressed as the polypeptide of SEQ ID NO: 2, treating the cancer cells with an anticancer candidate, and determining that the anticancer candidate is an anticancer substance when the candidate exhibits antagonistic activity against tumor formation and metastasis based on several events through the molecular mechanism of TM4SF5. The present invention also relates to chalcone compounds screened to have anticancer activity using the method, and an anticancer composition comprising the compound as an effective ingredient.

  • Patent number: 8658000
    Abstract: A preparation method of chromenone derivatives using radiation is provided. The preparation method exposes commercially-available silybin in reaction solvent to radiation, to thereby concurrently obtain both dehydrosilybin and apigenin compounds, which are chromenone compounds, in a simple reaction step and with high yield. Because the compounds are prepared at economic cost, the preparation method can be advantageously used particularly for the purpose of mass production. Further, in consideration of good cancer cell viability suppression effect thereof, dehydrosilybin and apigenin prepared according to the preparation method can be advantageously used as a pharmaceutical composition for prevention and treatment of cancer.

  • Patent number: 7851654
    Abstract: Disclosed relates to a novel chalcone derivative, pharmaceutically acceptable salt thereof, a method for preparing the same and uses thereof, the chalcone derivative being readily obtained through the steps of: reacting aminoacetophenone with sulfonylchloride under the presence of an appropriate salt; and reacting the compound prepared in the above step with hydroxybenzaldehide under the presence of an appropriate catalyst. The chalcone derivative of formula 1 in accordance with the present invention having strong enzyme inhibitory activities for glycosidase can be effectively used in preventing and treating various diseases induced by glycosidase, and the chalcone derivative of the invention having tyrosinase and melanin synthesis inhibitory activities can be effectively used as a skin-whitening compound.
