Application

Bovine aortic endothelial cells were treated with 22(R)-Hydroxycholesterol to study the effects on production of free radicals and in studies related to fatty acid metabolism.

Biochem/physiol Actions

22(R)-Hydroxycholesterol is an intermediate of the pregnenolone synthesis pathway from cholesterol. It reported has neuroprotective properties and protects the neurons against β-amyloid-induced cell death. 22(R)-Hydroxycholesterol acts as the ligand of liver X receptors that act as sensors of sterol concentration and regulates the fatty acid metabolism.

Preparation Note

22(R)-Hydroxycholesterol yield clear, colorless solution in chloroform.

Cholesterol, fatty acids, fat-soluble vitamins, and other lipids present in our diets are not only nutritionally important but serve as precursors for ligands that bind to receptors in the nucleus. To become biologically active, these lipids must first be absorbed

Ligand activation of liver X receptors (LXRs) has been shown to impact both lipid metabolism and inflammation. One complicating factor in studies utilizing synthetic LXR agonists is the potential for pharmacologic and receptor-independent effects. Here, we describe an LXR gain-of-function

The liver X receptor (LXR) has recently been described in salmonids. In mammals, this receptor is already known as a transcriptional factor that regulates diverse aspects of cholesterol, fatty acid and carbohydrate metabolism in various tissues, including muscle. Here we

Oxygenated cholesterol metabolites known as oxysterols display potent biological activities ranging from regulation of lipid homeostasis to cytotoxicity. Oxysterols have previously been shown to inhibit the invasion of first trimester trophoblasts, an effect which involves activation of the nuclear liver

Liver X receptors (LXR), which were originally reported as oxysterol-activated nuclear receptors, were recently found to recognize glucose as a physiological ligand. On this basis, we have already developed novel LXR antagonists based upon alpha-glucosidase inhibitors derived from thalidomide. Here
