  Efficient and Versatile Synthesis of Novel 2α-Substituted 1α,25-Dihydroxyvitamin D₃ Analogues and Their Docking to Vitamin D Receptors

  摘要：

  Novel 2 alpha -substituted 1 alpha ,25-dihydroxyvitamin D-3 analogues with 2 alpha -alkyl and 2 alpha -hydroxyalkyl groups were systematically synthesized from D-xylose. Their conformation on binding to the ligand binding domain (LBD) of the vitamin D receptor was analyzed. It has been found that the 2 alpha -hydroxypropyl group best fits the cavity of the LBD, and the binding activity is three times higher than that for the natural hormone.
