We report a stereoselective synthesis of the (25S)-cholestenoic-26-acids which are highly efficient ligands for the hormonal receptor DAF-12 in Caenorhabditis elegans.

3β-hydroxychol-5-en-24-oic acid (5). Our biological studies of the compounds 1–4 reveal that (25S)-Δ7-dafachronic acid (1) represents the most active steroidal ligand for the hormonal receptor DAF-12 in Caenorhabditis elegans. Moreover, the saturated (25S)-dafachronic acid (3) represents a new ligand for this receptor and the (25S)-steroidal acids are more active as compared to their corresponding
