Beschreibung

Application

Cholesterol 5α, 6α-epoxide was incorporated in culture medium of human arterial endothelial cells to study oxysterol-induced toxicity.[1]

Biochem/physiol Actions

Cholesterol 5α, 6α-epoxide is an oxysterol, a cholesterol derivative by auto-oxidation. Oxysterols are non-genomic regulators of cholesterol homeostasis.[2] The biological effects include protein prenylation, apoptosis, modulation of sphingolipid metabolism and platelet aggregation.[3] Oxysterols bind to liver X receptors, modulate cholesterol efflux and decrease the uptake of cholesterol by the cells.[2]

Preparation Note

Cholesterol 5α, 6α-epoxide yields clear, colorless solution in chloroform at 50 mg/ml.
