生化／生理作用

Demethylwedelolactone is a coumestan extracted from Eclipta alba that exhibits numerous biological activities including anti-inflammatory and hepato-protective. Demethylwedelolactone inhibits MDA-MB-231 breast cancer cells motility and invasiveness. It suppresses the metastasis and lung colonization of the tumor cells in the nude mice. Both demethylwedelolactone and wedelolactone appear to attenuate cigarette smoking extract induced inflammation through blockade of autophagy flux in respiratory epithelial cells.

Excessive autophagy plays a crucial role in cigarette smoking extract (CSE)-induced inflammation response and oxidative damage of respiratory epithelial cells. The components from Eclipta prostrata L. (CCE) have been shown to be beneficial for CSE-induced epithelial cells injury. However, whether

The hepatic injury due to oxidative stress was ameliorated through administration of an aqueous extract of Eclipta alba leaves and suggested that wedelolactone and demethylwedelolactone were the possible components of Eclipta alba behind the protective effect on liver as well

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
