3β-ヒドロキシコレスタ-5-エン-7-オン 化学特性,用途語,生産方法
説明
7-keto Cholesterol is a bioactive sterol and a major oxysterol component of oxidized LDL. It is produced by oxidation of cholesterol
via ethanol-mediated lipid peroxidation or photodamage as well as oxidation of 7-dehydro cholesterol by the cytochrome P450 (CYP) isoform CYP7A1. 7-keto Cholesterol inhibits CYP7A1 (IC
50 = ~1 μM). It induces activation and chemotaxis of retinal microglia as well as polarization to a pro-inflammatory state
via NLRP3 inflammasome activation
in vitro. Intraocular implantation of 7-keto cholesterol coated wafers increases ocular levels of VEGF, IL-1β, and GRO/KC, macrophage infiltration, and neovascularization in rat eye. Levels of 7-keto cholesterol in lipid deposits are increased in a variety of chronic diseases, including atherosclerosis, Alzheimer''s disease, and age-related macular degeneration.
