Quassinoids from Castela texana

Dou J, McChesney JD, Sindelar RD, Goins DK, Walker LA (1996) A New Quassinoid from Castela texana. J Nat Prod 59 73-76... [Pg.3361]

A new quassinoid, 11 -<9-iram-/ -coumaroyl amarolide (112) isolated from Castela texana and the structure was elucidated by spectroscopic analysis. Compound (112) is the first coumaroyl quassinoid derivative to be isolated from nature [50], Testing in the antimalarial bioassay showed that (112) possessed moderate antimalarial activity without potent cytotoxicity. [Pg.450]

The 5(R)- and 5(,S)-polyandranes (33 and 29), Zus-lactones, were isolated from Castela texana and Castela polyandra [17], respectively, and have been shown by single-crystal X-ray analysis to possess the novel carbon skeleton. In view of the structural similarity between the polyandranes and the C20 quassinoids, it has been suggested that (33) and (29) are derived biogenetically from chaparrinone (226) [134]. [Pg.480]
