  Practical Synthesis and Evaluation of the Biological Activities of 1α,25-dihydroxyvitamin D₃ Antagonists, 1α,25-dihydroxyvitamin D₃-26,23-lactams. Designed on the Basis of the Helix 12-Folding Inhibition Hypothesis

  摘要：

  A practical synthetic route to novel vitamin D antagonists of DLAM (1 alpha.,25-dihydroxyvitamin D-3-26,23lactam) was developed from vitamin D-2 via the 1,3-dipolar cycloaddition reaction as a key step. Six DLAM derivatives (24 compounds) with a variety of nitrogen substituents and stereochemistries at C23 and C25 were synthesized. Among these new derivatives, (23S,25S)-DLAM isomers bound effectively to VDRs and showed antagonistic activity in the HL-60 cell differentiation inhibition assay. The importance of the substituent on the nitrogen of DLAMs for antagonistic activity was also suggested by computational docking studies.
