Abstract
The 70% ethanol extract of Soymida febrifuga was found to kill PANC-1 human pancreatic cancer cells preferentially under nutrition-deprived conditions at a concentration of 10 microg/mL. Phytochemical investigation led to the isolation of 27 compounds including four new compounds [(3R)-6,4'-dihydroxy-8-methoxyhomoisoflavan (1), (2R)-7,4'-dihydroxy-5-methoxy-8-methylflavan (2), 7-hydroxy-6-methoxy-3-(4'-hydroxybenzyl)coumarin (3), and 6-hydroxy-7-methoxy-3-(4'-hydroxybenzyl)coumarin (4)]. 2',4'-Dihydroxychalcone (8) displayed the most potent preferential cytotoxicity (PC(50) 19.0 microM) against PANC-1 cells. In addition, the cytotoxic activity against colon 26-L5 carcinoma (colon 26-L5), B16-BL6 melanoma (B16-BL6), lung A549 adenocarcinoma (A549), cervix HeLa adenocarcinoma (HeLa), and HT-1080 fibrosarcoma (HT-1080) cell lines and their structure-activity relationship are discussed. The cytotoxic activity of 4'-hydroxy-3,5-dimethoxystilbene (6) against colon 26-L5 (IC(50) 2.96 microM) was found to be stronger than the positive control, doxorubicin, at IC(50) 3.12 microM.
