Flavonoids synthesized from chalcone precursors in plants have been shown to possess cytotoxic activities with therapeutic potential. We have isolated the novel chalcone flavokawain B from Alpinia pricei Hayata, a plant native to Taiwan that is used in food and traditional Chinese medicine. Here, we
Chalcones found in fruits and vegetables have promising cancer chemopreventive properties. This study attempts to identify the anticancer efficacies of chalcone flavokawain B (FKB) in the rhizomes of Alpinia pricei Hayata by examining key molecular events in non-small-cell lung cancer (A549) cells.
Alpinia pricei (Zingiberaceae) is a spicy herb indigenous to Taiwan. A potent anti-inflammatory compound, flavokawain B (FKB), was obtained from A. pricei. FKB significantly inhibited production of NO and PGE(2) in LPS-induced RAW 264.7 cells. Moreover, it also notably decreased the secretion of
Flavokawain B is a natural chalcone isolated from the rhizomes of Alpenia pricei Hayata. In the present study, we have investigated the antiproliferative and apoptotic effect of flavokawain B (5-20 μg/ml; 17.6-70.4 μM) against human squamous carcinoma (KB) cells. Exposure of KB cells with
