Anti-breast cancer agents from Chinese herbal medicines.

Chinese Herbal Medicines (CHM) have been used in disease prevention and treatment for centuries in China. A number of anti-breast cancer agents isolated from CHM recently, showed very interesting structures, although some of the mechanism of action is not quite clear. These unique chemical structures could be an important information resource for new anti-breast cancer drugs' design and discovery. This review summarizes these findings on anti-breast cancer agents from CHM.
