METHOD FOR INHIBITING ACTIVITY AND/OR EXPRESSION OF MATRIX METALLOPROTEINASE, INHIBITING PHOSPHORYLATION OF MITOGEN-ACTIVATED PROTEIN KINASE, AND/OR PROMOTING EXPRESSION OF COLLAGEN USING TORMENTIC ACID
A method for inhibiting the activity of matrix metalloproteinase (MMP), inhibiting the expression of matrix metalloproteinase, inhibiting the phosphorylation of mitogen-activated protein kinase (MAPK), and/or promoting the expression of collagen in a mammal is provided. The method comprises administrating to the mammal an effective amount of an active component selected from a group consisting of a compound of formula (I), a pharmaceutically acceptable salt of the compound, a pharmaceutically acceptable ester of the compound, and combinations thereof:
