Abstract
In vitro studies showed that several flavonoids, tannic acid, gallic a cid and fat-soluble vitamins inhibited HeLa and Raji lymphoma cell gro wth. The inhibition trend exhibited by these compounds was similar for both cell lines, and their growth was inhibited dose dependently. But ein, (10-mu-M), the most potent anti-proliferative agent, exerted 30% growth inhibition and was more effective on HeLa cells. Retinol (100-m u-M) inhibited cell proliferation completely. Tannic acid was twice as potent as its monomer gallic acid. From structure-activity considerat ion, the C2,3-double bond of the flavonoid molecule was important for activity. Flavonoid aglycones were more effective than their correspon ding glycosides in suppressing cell growth.
