Description_x000D_ Application_x000D_ Diethylumbelliferyl phosphate has been used as a lipase inhibitor to treat wild-type myeloblasts for in vitro neutrophil differentiation assays._x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Diethylumbelliferyl phosphate (DEUP), an organophosphate does not block protein kinase activity A in vitro._x000D_ Diethylumbelliferyl phosphate is a selective, potent cholesterol esterase inhibitor. It blocks steroidogenesis primarily by preventing cholesterol transport into the mitochondria of steroidogenic cells. Inhibitors of cholesterol esterase are anticipated to limit the absorption of dietary cholesterol. IC50 = 11.6 μM.
