title: 5,6-Trans-25-hydroxycholecalciferol: vitamin D analog effective on intestine of anephric rats.
abstract: A new compound, 5,6-trans-25-hydroxycholecalciferol, has been synthesized and tested for its biological activity. Like 1,25-dihydroxycholecalciferol, it stimulates intestinal calcium transport in anephric rats, whereas 25-hydroxycholecalciferol does not. But this analog has little if any activity in stimulating mobilization of calcium from the bone of anephric rats.
