Biological Activity:
Esculetin, a phenolic compound, acts as a 5-LO (5-lipoxygenase; 5-LOX) inhibitor. Esculetin is reported to display antiinflammatory and antioxidant properties, as well as induce cell cycle arrest and apoptosis. In the presence of esculetin and HA14-1 expression of the death receptor 4 (DR4) has been observed to be upregulated and extracellular-regulated kinase (ERK) to be activated. Other studies suggest that esculetin upregulates death receptor 5 (DR5) protein expression, and enhances TRAIL-induced apoptosis. Additionally, reports demonstrate that Esculetin also inhibits the activity of 12-LO (12-lipoxygenase), and decreases leukotriene biosynthesis during 5-LO inhibition.
