Description

CAS: 305-01-1 | C9H6O4 | 178.143 g/mol

In the presence of esculetin and HA14-1 (sc-205911) 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. It also inhibits the activity of 12-LO (12-lipoxygenase), and decreases leukotriene biosynthesis during 5-LO inhibition.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
