Introduction of 566-28-9 :

7-Ketocholesterol is an oxidation product of cholesterol, widely present in atherosclerotic plaques, and has a stronger atherogenic effect than cholesterol. 7-Ketocholesterol can inhibit the rate-limiting enzymes involved in bile acid and cholesterol synthesis, such as cholesterol 7α-hydroxylase and HMG-CoA reductase. 7-Ketocholesterol exhibits pro-inflammatory effects both in vivo and in vitro and can induce cell apoptosis (apoptosis)[1]. In Vitro: 7-Ketocholesterol (50 μM, 2.5-2 hours) can enhance leukocyte-endothelial cell adhesion via the p38 MAPK pathway[4].
7-Ketocholesterol (2.5-40 μg/mL, 24 hours) induces apoptosis in a dose-dependent manner by activating caspase-3/7, -8, and -12 in human microvascular endothelial cells[5]. In Vivo: 7-Ketocholesterol (5-20 mg/mL, administered via biodegradable wafers implanted into the anterior chamber of rats' eyes, single dose) exhibited pro-angiogenic and pro-inflammatory effects in Brown Norway rats[1].
