7α,24(S)-Dihydroxycholesterol ((3β,7α,24S)-Cholest-5-ene-3,7,24-triol) acts as a ligand for liver X receptors (LXR), specifically binding to the ligand-binding domains of LXRα and LXRβ. This compound is synthesized through the E-α,β-unsaturated ketone process, starting with arsindole and J-secondary-butyl dimethylsiloxy-bis-positive-5-cholestenal as the initial materials. It undergoes a series of transformations to produce 7α,24(S)-dihydroxycholesterol.
