Amino and nitro derivatives of 5,7-dimethoxyflavone from Kaempferia parviflora and cytotoxicity against KB cell line.
Structural modification of 5,7-dimethoxyflavone isolated from Kaempferia parviflora furnished two nitro and seven amino derivatives. Among these, six new (3, 5-6, 8-10) and three known (2, 4, 7) flavonoid derivatives were synthesized. All compounds were evaluated for cytotoxicity against KB cell line using colorimetric method. Compounds 6 and 8 exhibited strong cytotoxicity with IC50 values of 6.80 and 5.84 microg/mL, respectively.
