一般描述
5α,6α-epoxycholestanol (5α,6α-EC) is generated by cholesterol epoxidation and is a diastereoisomer of 5β,6β-epoxycholestanol (5β,6β-EC).
应用
5α,6α-epoxycholestanol has been used as a sterol internal standard in ultra-performance liquid chromatography–high resolution mass spectrometry (UPLC-ESI-HRMS) analysis to quantify mice brain sterols. It may be used in calibration curve generation for the quantification of phytosterols in food samples and as an internal standard for oxysterol quantification in biological samples by gas chromatography-mass spectrometry (GC-MS)
生化/生理作用
5α,6α-epoxycholestanol (5α,6α-EC) is a liver X receptor (LXR) antagonist. It mimics cholesterol in phosphatidylcholine vesicles and is a substrate for acyl-coenzyme A:cholesterol acyltransferase (ACAT). 5α,6α-EC is employed in anticancer treatments. It is catabolized by the enzyme cholesterol-5,6-epoxide hydrolase (ChEH) enzyme to 3β,5α,6β-triol. 5α,6α-EC impairs redox state and affects atherogenesis. The levels of 5α,6α-EC is elevated in hypercholesterolemia and mediates steroid receptor coactivator (SRC) recruitment.
