Abstract: The present invention relates to a composition for enhancing immunity through inducing the expression of interferon-? comprising a compound represented by Formulas 1 to 8, or Sophora flavescens extract comprising the same and fractions thereof as an active ingredient, a feed additive, feed composition, pharmaceutical composition, food composition, and over-the-counter (OTC) drug composition comprising the composition, and a method for enhancing immunity through administrating the composition. A composition for inducing the expression of interferon-?, comprising a compound represented by Formulas 1 to of the present invention, Sophora flavescens extract comprising the same, or fractions thereof as active ingredient can prevent, alleviate, or treat the diseases that can be prevented or treated by increasing the expression of interferon.

Abstract: Disclosed is a composition comprising a turmeric extract for preventing and treating influenza virus infection and for inhibiting neuraminidase activity. A turmeric extract, its fraction, and a curcuminoid-based compound separated therefrom may inhibit neuraminidase activity and have antiviral and cell degeneration inhibitory effects on influenza virus, and may be useful in preventing and treating influenza virus infection.

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.

Abstract: The present invention relates to a composition for preventing or treating rotavirus infection, comprising a licorice extract, fractions thereof or compounds separated therefrom. The licorice extract, fractions thereof or compounds separated therefrom have anti-rotavirus effects and exhibit not only virucidal effects against various rotaviruses, but also the effect of inhibiting the cytopathic effect of rotaviruses. Thus, the composition can be effectively used for the prevention or treatment of rotavirus infection.

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.

Abstract: Disclosed is a composition comprising a turmeric extract for preventing and treating influenza virus infection and for inhibiting neuraminidase activity. A turmeric extract, its fraction, and a curcuminoid-based compound separated therefrom may inhibit neuraminidase activity and have antiviral and cell degeneration inhibitory effects on influenza virus, and may be useful in preventing and treating influenza virus infection.

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.
