Development of 14-epi-19-nortachysterol and its unprecedented binding configuration for the human vitamin D receptor

In the study of the synthesis of 14-epi-19-norprevitamin D3, we found 14-epi-19-nortachysterol derivatives through C6,7-cis/trans isomerization. We also succeeded in their chemical synthesis and revealed their marked stability and potent VDR binding affin
