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.
