    • Chemical Class:

      A hydroxycalciol that is calcitriol which has undergone formal oxidative coupling at positions 20 and 23 to the hydroxy group and methyl group, respectively, of methanol to afford the corresponding ox olane ring (the 20<stereo>S</stereo>,23<stereo>S</stereo> stereoisomer). It is a superagonist of the vitamin D nuclear receptor in vitro, but is as calcemic in vivo as the natural ligand. ChEBI CHEBI:139026
