vitamin d receptor

Calcitriol (1,25-Dihydroxyvitamin D3) is a metabolite of vitamin D and a vitamin D receptor (VDR) agonist (IC50=0.4 nM). Calcitriol increases intestinal absorption of calcium and phosphorus, and increases bone resorption with parathyroid hormone.

Ergocalciferol (Vitamin D2 (Calciferol)) is a derivative of ergosterol formed by ultraviolet rays breaking of the C9-C10 bond with a strong inhibitory effect against bladder tumor promotion by sodium saccharin, and it induces cell differentiation in leukemia cells. Vitamin D2 is an inhibitor of DNA Polymerase.

Calcifediol (U 32070E) is a naturally occurring product that is metabolized in the liver from vitamin D3, a VDR ligand. Calcifediol is indicated for use as a vitamin supplement for all patients with vitamin D deficiency.

(1S)-Calcitriol (1α,25-Dihydroxy-3-epi-vitamin-D3), a natural metabolite of 1α,25-dihydroxyvitamin D3 (1α,25(OH)2D3), exerts potent actions through vitamin D receptor (VDR) activation, including the inhibition of keratinocyte growth and suppression of parathyroid hormone secretion [1].

Calcitroic acid is a vitamin D receptor (VDR) agonist that activates VDR-mediated transcription. It is the primary metabolite of 1,25-dihydroxyvitamin D3, showing the highest concentrations in the liver and mucosa of mice. The compound exhibits metabolic stability and extremely low toxicity.
