• Beschreibung

  The liver X receptors (LXRα and LXRβ) are nuclear hormone receptors whose native ligands are oxysterols.¹ Acetyl podocarpic acid anhydride (APD) is a potent, semisynthetic LXR agonist derived from extracts of the mayapple. APD acting through LXR in concert with the retinoid X receptor (RXR), its heterodimerization partner, induces the expression of the ABCA1 reverse cholesterol transporter.² This acts to increase the efflux of cholesterol from enterocytes and thus inhibits the overall absorption of cholesterol (ED₅₀ value of 1 nM).³ In transient transactivation assays, APD was found to be approximately 1,000 times more potent and have 8-10-fold greater maximal stimulation of LXR than 22(R)-hydroxy cholesterol.^3,4 APD can be used as a positive control for the testing of LXR agonists, which have potential as therapeutic agents for the treatment of atherosclerosis.
