Abstract
|
|
|
|
In an effort to increase of the antitumor activity of 2(S)-,-trihydroxy-7, 8-dimethoxyflavanone isolated from Scutellaria indica, we synthesized its analogues, II, III and IV. They showed potent cytotoxicity in vitro against cancer cell lines, L1210, K562 and A549. On the basis of values against the cancer cell lines, III exhibited about 2-7 times stronger activity than I against various cell lines. We tested the antitumor activity of the analogues against Sarcoma 180 cells in vivo and evaluated the structure-activity relationship. The antitumor activity appeared to be related to the hydrogen bond between carbonyl group at C-4 and hydroxyl group at C-5, in contrast to cytotoxic action.
