1β-CALCITRIOL is an Impurity B of Calcitriol. Calcitriol(1,25-Dihydroxyvitamin D3; Rocaltrol ) is the hormonally active form of vitamin D, Calcitriol is the active metabolite of vitamin D3 that activates the vitamin D receptor (VDR). 1-epicalcitriol is a potent antagonist of 1,25(OH)2D3-induced intestinal calcium
transport (transcaltachia).
Approval Year
Sample Use Guides
The action of 1-epicalcitriol on the murine fibroblastic cell line C3H10T1⁄2 was examined over a concentration range of 10(-5)–10(-13) M. 1-epicalcitriol was the best proliferation-inhibitor of the A-ring derivatives of 1,25(OH)2D3 with 30% inhibition at 10(-10) M. 1-epicalcitriol was slightly more active
than NS3 and 25(OH)D3 with nearly three times higher
CAT-activity at 10(-8) M.
