METHODS AND RESULTS:
A bioassay-guided fractionation and purification resulted in the isolation and characterization of seven quassinoids including brusatol, bruceine D, bruceine H, yadanzioside A, Yadanzioside G, javanicoside C and bruceantinoside A. Among them, brusatol exhibited the most potent in vitro antipancreatic cancer action, with IC(50) values of 0.36 μm and 0.10 μm on PANC-1 and SW1990 cell lines, respectively.
CONCLUSIONS:
This is the first report on the antipancreatic adenocarcinoma activity of brusatol. | | Bull. Chem. Soc. Jpn.,1985, 58(9), 2680-6. | | Structures of new quassinoid glycosides, yadanziosides A,B,C,D,E,G,H, and new quassinoids, dehydrobrusatol and dehydrobruceantinol from Brucea javanica (L.) Merr.[Reference: WebLink] |
METHODS AND RESULTS:
Quassinoid glycosides, yadanzioside A, yadanzioside B, yadanzioside C, yadanzioside D, yadanzioside E, Yadanzioside G, and yadanzioside H, and two quassinoids, dehydrobrusatol and dehydrobruceantinol were isolated from seeds of Brucea javanica, and their structures were determined.
CONCLUSIONS:
These glycosides showed bitter taste and were demonstrated to have antileukemic activity. |
