摘要

The anticancer properties of demethylwedelolactone (DWEL) and wedelolactone (WEL), which are naturally occurring coumestans, have not been well characterized. In this study, we investigated the anti-invasive effects of synthetic WEL and DWEL on human MDA-MB-231 breast cancer cells. We found that WEL and DWEL inhibited the anchorage-independent growth and also suppressed cell motility and cell invasion of MDA-MB-231 cells. In addition, WEL and DWEL reduced the activity and expression of matrix metalloproteinases (MMPs) involved in blocking the IκB-α/NFκB and MEK/ERK signaling pathways in MDA-MB-231 cells. Furthermore, DWEL suppressed the metastasis and lung colonization of the tumor cells in the nude mice. Altogether, these data suggest that DWEL derivatives exert anti-invasive growth effect on breast cancer cells.Copyright © 2012 Elsevier Masson SAS. All rights reserved.
