CAS 566-27-8: 7β-Hydroxycholesterol

7 Beta-Hydroxycholesterol (7β-Hydroxycholesterol) is an oxidative stress inducer that promotes atherosclerosis.

7b-Hydroxycholesterol is a cholesterol metabolite that is formed from 7-alpha-hydroxylase by cytochrome P450. It has been shown to induce apoptosis in a number of carcinoma cell lines, including HL-60 cells and human prostate cancer cells. 7b-hydroxycholesterol was also shown to be an effective inducer of the formation of body structures by cultured cells. It has been found to be potent inducers of the synthesis of oxysterols, which are natural compounds that have been shown to inhibit viral replication. The effects on body formation and viral inhibition may be due to its ability to bind to the mitochondrial membrane potential, inhibiting ATP binding cassette transporter and enzyme activities.

Applications A metabolite of Cholesterol. Its membrane organizing properties could have implications in Altzheimer’s disease.
