calcitriol

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.

Impurity B of Calcitriol is an impurity of Calcitriol. Calcitriol is the hormonally active form of vitamin D, Calcitriol is the active metabolite of vitamin D3 that activates the vitamin D receptor (VDR).

Calcitriol Derivatives is an analog of vitamin D3.

Calcitriol Impurities A refers to the contaminants found in Calcitriol, the hormonally active metabolite of vitamin D3, which serves to activate the vitamin D receptor.

Calcitriol D6 is the deuterated form of Calcitriol, which is the hormonally active form of vitamin D. Calcitriol is the active metabolite of vitamin D3 that activates the vitamin D receptor.

Impurity C of Calcitriol is an impurity of Calcitriol.Impurity C of Calcitriol is used in the synthesis of vitamin D3.

Calcitriol Impurities D (24-Homo Calcitriol) is a hormonal form of the vitamin that promotes the differentiation of HL-60 human promyelocytic leukemia cells into monocytes.Calcitriol Impurities D has bone resorption activity and inhibits the replication of human immunodeficiency virus in human cells.Calcitriol Impurities D has antiviral activity and can be used to treat AIDS and viral infections. 25-dihydroxyvitamin D3 has antiviral activity and can be used in the treatment of AIDS and viral infections.

Calcitriol lactone (1α,25-Dihydroxyvitamin D3-26,23-lactone), a vitamin D3 metabolite, serves as the active form of vitamin D, influencing bone health, cell differentiation, and immune function.

(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].

Calcitriol-13C3 is a 13C-labeled form of calcitriol. Calcitriol is the most potent metabolite of vitamin D and acts as an agonist of the vitamin D receptor (VDR).

Calcitriol (Standard) is a reference standard for research and analysis in studies involving Calcitriol. 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.

Falecalcitriol is an analog of calcitriol. It has a higher potency both in vivo and in vitro systems, which is longer duration of action in vivo.

Ercalcitriol (1α,25-Dihydroxy Vitamin D2) is an active metabolite of vitamin D2 that strengthens immunity by regulating cathelicidin antimicrobial peptide (CAMP) and defensin β-4 (DEFB4) genes in normal and transformed cells, combating pathogenic infections.

Maxacalcitol (22-Oxacalcitriol) is a ligand of VDR-like receptors and a non-serum calcium vitamin D3 analogue. Maxacalcitol inhibits parathyroid hormone (PTH) mRNA expression in vitro and in vivo.

Elocalcitol is a calcitriol analog for inhibition of prostate cell growth.

Tpl2 kinase inhibitor is an inhibitor of tumor progression locus 2 (Tpl2; IC50= 0.05 μM).1It is selective for Tpl2 over MEK, p38 MAPK, Src, MK2, and PKC (IC50s = >40, 180, >400, 110, and >400 μM, respectively). Tpl2 kinase inhibitor inhibits LPS-induced TNF-α production in isolated human monocytes and whole blood (IC50s = 0.7 and 8.5 μM, respectively). It enhances differentiation induced by calcitriol in HL-60 and U937 leukemia cells when used at a concentration of 5 μM.2Tpl2 kinase inhibitor (5 μM) inhibits the proliferation of KG-1a leukemia cells.3 1.Garvin, L.K., Green, N., Hu, Y., et al.Inhibition of Tpl2 kinase and TNF-α production with 1,7-naphthyridine-3-carbonitriles: Synthesis and structure-activity relationshipsBioor.
