K. Mohamad et al., ARGENTEANONES-C-E AND ARGENTEANOLS-B-E, CYTOTOXIC CYCLOARTANES FROM AGLAIA-ARGENTEA, Journal of natural products, 60(2), 1997, pp. 81-85
Seven new cycloartanes, argenteanones C-E (4-6) and argenteanols B-E (
7-10), have been isolated from Aglaia argentea leaves. All of these co
mpounds possess significant cytotoxic activity against KB cells (IC50
values between 3.7 and 6.2 mu g/mL). Structure elucidation was perform
ed by 2D NMR spectroscopy, aided by molecular modeling in the case of
the side chain of compound 7.
