Calcitriol is a nonselective vitamin D receptor activator/agonist(VDRA), exhibiting a 10-fold higher vitamin D receptor (VDR) binding affinity(IC50=0.4 nM) than the selective VDRA paricalcitol.



Alfacalcidol is a non-selective VDR activator medication.


Vitamin C

Vitamin C is a water-soluble vitamin indicated for the prevention and treatment of scurvy.



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



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



Trolox is a cell-permeable, water-soluble derivative of vitamin E with potent antioxidant properties.


Biotin (Vitamin B7)

Biotin is a water-soluble B-vitamin and is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids.


Vitamin B12

Vitamin B12 is a water soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood.



Phenindione is an anticoagulant which functions as a Vitamin K antagonist.


Nicotinic Acid

Nicotinic Acid is a water-soluble vitamin belonging to the vitamin B family.


cholecalciferol (Vitamin D3)

Vitamin D3 is a form of vitamin D, binds and activates a H305F/H397Y mutant vitamin D receptor (VDR) with EC50 of 300 nM.


Beta Carotene

Beta Carotene is an organic compound and classified as a terpenoid. It is a precursor (inactive form) of vitamin A.



Riboflavin is an easily absorbed micronutrient with a key role in maintaining health in humans and other animals.


Thiamine HCl (Vitamin B1)

Thiamine or vitamin B1 is a water-soluble vitamin of the B complex, its phosphate derivatives are involved in many cellular processes.


Calcium D-Panthotenate

Calcium D-Panthotenate, also called vitamin B5 Calcium, is a water-soluble vitamin and an essential nutrient for many animals.


Retinyl (Vitamin A) Palmitate

Vitamin A palmitate is a more stable, synthetic version of the essential nutrient vitamin A joined to palmitic acid.


Amprolium HCl

Amprolium chloride is a thiamin antagonist, which prevents carbohydrate synthesis by blocking thiamine uptake.


Folic acid

Folic acid, a B vitamin, plays an important role in cell division and in the synthesis of amino acids and nucleic acids like DNA.



Ergosterol is a sterol and a biological precursor (a provitamin) to vitamin D2.


D panthenol

Dexpanthenol is an alcoholic analogue of D-pantothenic acid and cholinergic agent.


Vitamin A Acetate

Vitamin A is a group of unsaturated nutritional hydrocarbons, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, among which beta-carotene is the most important.


Pyridoxine HCl

Pyridoxine HCl is a form of vitamin B6.


Sodium ascorbate

Sodium Ascorbate is a more bioavailable form of vitamin C that is an alternative to taking ascorbic acid as a supplement.
