7-KETOCHOLESTEROL C화학적 특성, 용도, 생산

개요

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 (IC₅₀ = ~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.
