  The First Locked Side-Chain Analogues of Calcitriol (1α,25-Dihydroxyvitamin D₃) Induce Vitamin D Receptor Transcriptional Activity

  摘要：

  [GRAPHIC]We describe the synthesis of the first locked side-chain analogues of the natural hormone 1alpha,25-(OH)(2)-D-3 and their effects on gene transcription in human colon cancer cells. Analogue 2 was more potent than 1alpha,25-(OH)(2)-D-3 at inducing vitamin D receptor (VDR) transcriptional activity. Analogues 3a and 3b show potency similar to that of 1alpha,25-(OH)(2)-D-3, whereas 3c was less active. The novel analogues efficiently bind VDR in vivo to induce transcription from a consensus vitamin D responsive element (VDRE).
