1α-Hydroxyvitamin D3 is a form of vitamin D that helps the body absorb calcium from food.

22-Oxacalcitriol is a Vitamin D3 analog which is Non-calcemic as well as a VDR ligand. 22-Oxacalcitriol has been shown to decrease parathyroid hormone (PTH) mRNA expression in vitro. Additionally has been noted to exhibit similar effects to calcitriol in

25-Hydroxyvitamin D2 is used in serum to measure the concentration of vitamin D produced by the skin. It is known that 25-Hydroxyvitamin D2 can be detected in human serum using high-performance liquid chromatography and ultraviolet detection. Vitamin D2,

Calcifediol is a major circulating metabolite of vitamin D3, acting as a competitive inhibitor with an apparent Ki of 3.9 μM, suppresses PTH secretion and mRNA (ED50=2 nM).

Calcipotriol is a synthetic VitD3 analogue with a high affinity for the vitamin D receptor.

Calcitriol is the most active metabolite of vitamin D and also a vitamin D receptor (VDR) agonist.

Doxercalciferol is a synthetic vitamin D2 analog, suppressing parathyroid synthesis and secretion, used to treat secondary hyperparathyroidism and metabolic bone disease.

EB1089 is an analog of 1,25 dihydroxyvitamin D which acts as a vitamin D receptor (VDR). EB1089 is noted to reverse hypercalcemia and is a potent inhibitor of PTH-rP (parathyroid hormone-related peptide, PTHRP) in vitro. In studies utilizing a squamous ca

Tacalcitol is a synthetic vitamin D3 analog. This compound has been shown to regulate calcium levels and induce nerve growth factor production in epidermal keratinocytes. Additionally, Tacalcitol has been noted to promotes normal bone development by regul

CB1151 is a 20-epi analogue of 1,25 dihydroxyvitamin D3 (VD) with potent anti-tumor effects. CB1151 inhibits MCF-7 cell growth with an IC50 value of 0.82 nM.

ZK159222, a 25-carboxylic ester analogue of 1α,25-(OH)2D3, is a potent 1α,25-(OH)2D3 receptor (VDR) agonist. The mechanism of ZK159222 antagonistic action is mediated by a lack of ligand-induced vitamin D receptor interaction with coactivators. ZK159222 has a partial agonistic character.

TEI-9647 is a first and potent VDR/vitamin D-responsive element (DRE)-mediated genomic actions antagonist. TEI-9647 is a 1α,25-dihydroxyvitamin D3-26,23-lactone (1α,25-lactone) analogue.

ZK168281 is a 25-carboxylic ester 1α,25(OH)2D3 analog and a pure VDR antagonist with a Kd value of 0.1 nM. ZK168281 is an effective inhibitor of the coactivator (CoA) interaction of its receptor.

1alpha, 24, 25-Trihydroxy VD2 is a vitamin D analog.

5,6-trans-Vitamin D3 (5,6-trans-Cholecalciferol;5,6-trans-Colecalciferol) is a photoproduct of vitamin D3. Vitamin D3 is a naturally occuring form of vitamin D. Vitamin D3 induces cell differentiation and prevents proliferation of cancer cells.

Triciferol functions as a multiple ligand with combined VDR agonist and HDAC antagonist activities. Triciferol binds directly to the VDR (IC50=87 nM), and functions as an agonist with 1,25D-like potency on several 1,25D target genes. Triciferol induces marked tubulin hyperacetylation, and augments histone acetylation at concentrations that largely overlap those where VDR agonism is observed. Antiproliferative and cytotoxic activities.

TEI-9648, a Vitamin D3 Lactone analogue, is a potent and specific vitamin D receptor (VDR) antagonist. TEI-9648 inhibits VDR/VDRE-mediated genomic actions of 1α,25(OH)2D3. TEI-9648 also inhibits HL-60 cell differentiation induced by of 1α,25(OH)2D3. TEI-9648 has the potential for bone metabolism research.

Inecalcitol (TX 522), a unique vitamin D3 analog, is an orally active vitamin D receptor (VDR) agonist. Inecalcitol can induce cell apoptosis and has potent anticancer activities[3.

A synthetic vitamin D3 analog that usually prescribed by a general practitioner or dermatologist for the treatment of psoriasis, chronic chapped lips and other severe dry skin conditions.

MeTC7 is a Vitamin-D receptor (VDR) antagonist. MeTC7 has potent VDR inhibition activity with an IC50 value of 2.9 μM. MeTC7 shows good antitumor effects.

2MD is an orally active vitamin D analog. 2MD stimulates periosteal bone formation and decreases trabecular bone resorption. Thus 2MD restores trabecular and cortical bone mass and strength. 2MD also regulates intraocular pressure (IOP)-relative genes and reduces IOP in non-human primates.
