  Syntheses and biological evaluation of novel 2α-substituted 1α,25-dihydroxyvitamin D3 analogues

  摘要：

  Novel 2 alpha-substituted 1 alpha,25-dihydroxyvitamin D-3 analogues were efficiently synthesized and their biological activities were evaluated. 2 alpha-Methyl-1 alpha,25-dihydroxyvitamin D-3 (2), whose unique biological activities were previously reported, was modified to 2 alpha-alkyl (ethyl and propyl) and 2 alpha-hydroxyalkyl (hydroxymethyl, hydroxyethyl, and hydroxypropyl) analogues 3-7 by elongation of the alkyl chain and/or introduction of a terminal hydroxyl group. 2 alpha-Hydroxypropyl-1 alpha,25-dihydroxyvitamin D-3 (7) exhibited an exceptionally potent calcium-regulating effect and a unique activity profile.

  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.
