7α,24(S)-Dihydroxycholesterol

7α,24(S)-Dihydroxycholesterol ((3β,7α,24S)-Cholest-5-ene-3,7,24-triol) serves as a ligand for liver X receptor (LXR), binding specifically to the ligand binding domains of both LXRα and LXRβ. This compound is synthetically produced from E-α,β-enone, utilizing Arsonium ylide and J-tert-butyldimethylsilyloxy-bisnor-5-cholenaldehyde as starting materials, followed by a series of transformations to yield 7α,24(S)-dihydroxycholesterol.
