Description and Uses
7α-hydroxy Cholesterol-d7 is intended for use as an internal standard for the quantification of 7α-hydroxy cholesterol by GC- or LC-MS. 7α-hydroxy Cholesterol is an oxysterol and a precursor in the biosynthesis of the bile acids cholic acid (CA; ) and chenodeoxycholic acid (CDCA; ). It is formed via the oxidation of cholesterol by cholesterol 7α-hydroxylase/CYP7A1 in rat liver microsomes. 7α-hydroxy Cholesterol (40 μM) increases levels of the adhesion molecules ICAM-1, VCAM-1, and E-selectin in human umbilical vein endothelial cells (HUVECs). It increases secretion of chemokine (C-C motif) ligand 2 (CCL2) and matrix metalloproteinase-9 (MMP-9) in serum-deprived THP-1 cells when used at a concentration of 5 μg/ml. 7α-hydroxy Cholesterol has been found in macrophages isolated from atherosclerotic lesions in rabbits fed a high-cholesterol diet.
7α-hydroxycholesterol-d7 has been used as an internal standard for cholesterol and oxysterol measurement by gas chromatography-mass spectrometry (GC/MS).
