Abstract:

Seven nitrile-containing gambogic acid derivatives were synthesized from gambogic acid(GA) through introducing different alkylnitriles or arylnitriles on the C-30 carboxyl of gambogic acid. Six of them are new compounds(1~6). Their structures were identified by 1H NMR and MS analysis. The evaluation of antitumor bioactivities in vitro on the hepatoma cells(HepG2), colon adenocarcinoma cells(RKO) and ovarian adenocarcinoma cells(OVCAR-3) were done by the methylthiazolydiphenyl-tetrazolium bromide(MTT) method. The results show that most of the synthesized compounds have strong antitumor activities. Among them, the antitumor activities of compounds 4 and 6 are more potent than that of gambogic acid.
