25(R)-27-hydroxy Cholesterol

The liver X receptors (LXRalpha and LXRbeta) are nuclear hormone receptors whose native ligands, oxysterols, induce the expression of genes involved in cholesterol and fatty acid metabolism. 27-hydroxy Cholesterol, a sterol 27-hydroxylase-mediated cholesterol hydroxylation product, activates LXRalpha and LXRbeta in vitro with EC50 values of 85 and 71 nM, respectively, and is a potent suppressor of cholesterol biosynthesis. 25(R)-27-hydroxy Cholesterol is the more predominant-occurring (~80%) stereoisomer of the endogenous oxysterol 27-hydroxy cholesterol.Formal Name: (25R)-cholest-5-ene-3beta,26-diol.
