  Cytotoxicity against KB and NCI-H187 cell lines of modified flavonoids from Kaempferia parviflora

  摘要：

  Flavones 1-4 isolated from Kaempferia parviflora were used for structural modification. Sixteen flavonoid derivatives, including four new derivatives, were synthesized and evaluated for cytotoxicity against KB and NCI-H187 cell lines. Flavanones 2a-4a demonstrated higher cytotoxic activity than the parent compounds. Cytotoxicity against KB cell line of oxime 1c was about 7 times higher than the ellipticine standard. Interestingly, oximes 1c and 2c exhibited highly potent cytotoxicity against NCI-H187 cell line with IC50 values of 0.014 and 0.23 mu M, respectively. Oximes 4c and 5c showed strong cytotoxicity against NCI-H187 cell line with IC50 values of 4.04 and 2.32 mu M, respectively. (C) 2010 Elsevier Ltd. All rights reserved.
