Abstract Title:
Anticancer Effects of Five Biflavonoids fromL. Male Flowers In Vitro.
Abstract:
L., an ancient dioecious gymnosperm, is now cultivated worldwide for landscaping and medical purposes. A novel biflavonoid-amentoflavone 7''-O-β-D-glucopyranoside ()-and four known biflavonoids were isolated and identified from the male flowers of. The anti-proliferative activities of five biflavonoids were evaluated on different cancer lines. Bilobetin () and isoginkgetin () exhibited better anti-proliferative activities on different cancer lines. Their effects were found to be cell-specific and in a dose and time dependent manner for the most sensitive HeLa cells. The significant morphological changes validated their anticancer effects in a dose-dependent manner. They were capable of arresting the G2/M phase of the cell cycle, inducing the apoptosis of HeLa cells dose-dependently and activating the proapoptotic protein Bax and the executor caspase-3. Bilobetin () could also inhibit the antiapoptotic protein Bcl-2. These might be the mechanism underlying their anti-proliferation. In short, bilobetin () and isoginkgetin () might be the early lead compounds for new anticancer agents.
