Vitamins

Ercalcidiol-d₃ is the deuterium labeled Ercalcidiol. Ercalcidiol is a metabolite of Vitamins D2. Ercalcidiol can be used as an indicator of vitamins D status.

Nicotinamide-¹⁵N,¹³C₃ is the ¹³C-labeled and ¹⁵N-labeled Nicotinamide. Nicotinamide is a form of vitamin B3 that plays essential roles in cell physiology through facilitating NAD+ redox homeostasis and providing NAD+ as a substrate to a class of enzymes that catalyze non-redox reactions. Nicotinamide is an inhibitor of SIRT1.

Biotin-d₂-1 is the deuterium labeled Biotin. Biotin is an enzyme co-factor present in minute amounts in every living cell.

Doxercalciferol-d₃3 is the deuterated form of Doxercalciferol, which is a Vitamin D2 analog that acts as a vitamin D receptor activator (VDRA).

(2RS,4R,8R)-δ-Tocopherol-d₄ (Mixture of Diastereomers) is the deuterium labeled (2RS,4R,8R)-δ-Tocopherol (Mixture of Diastereomers).

Vitamin D2-d₆ is the deuterium labeled Vitamin D2. Vitamin D2 (Ergocalciferol), drived from plant sources or dietary supplements, could be used as supplement of Vitamin D.

Pyridoxal phosphate-d₅ is the deuterium labeled Pyridoxal phosphate. Pyridoxal phosphate is the active form of vitamin B6, acts as an inhibitor of reverse transcriptases, and is used for the treatment of tardive dyskinesia.

Vitamin D3-¹³C₅ is the ¹³C-labeled Vitamin D3 (HY-15398). Vitamin D3 (Cholecalciferol) is a naturally occuring form of vitamin D. Vitamin D3 induces cell differentiation and prevents proliferation of cancer cells.

α-Vitamin E-¹³C₆ is the ¹³C-labeled α-Vitamin E. α-Vitamin E ((+)-α-Tocopherol), a naturally occurring vitamin E form, is a potent antioxidant.

Isonicotinamide-d₄ is the deuterium labeled Isonicotinamide.

3-epi-25-Hydroxy Vitamin D3-d₆ is the deuterium labeled 3-epi-25-Hydroxy Vitamin D3 (HY-142140). 3-epi-25-Hydroxy Vitamin D3 is the vitamin D metabolite, while vitamin D metabolism highly dependent on macrophage polarization. The C3-epimerase pathway for vitamin D is active in macrophages.

3-Pyridine-2,4,5,6-d₄ -carboxylic acid, ethyl ester is the deuterium labeled 3-Pyridine-2,4,5,6-carboxylic acid, ethyl ester.

DL-alpha-Tocopherol-d₉ is the deuterium labeled DL-alpha-Tocopherol. DL-alpha-Tocopherol is a synthetic vitamin E, with antioxidation effect. DL-alpha-Tocopherol protects human skin fibroblasts against the cytotoxic effect of UVB.

Pyridoxine-d₅ (hydrochloride) is the deuterium labeled Pyridoxine hydrochloride. Pyridoxine hydrochloride (Pyridoxol;Vitamin B6) is a pyridine derivative. Pyridoxine (Pyridoxol;Vitamin B6) exerts antioxidant effects in cell model of Alzheimer's disease via the Nrf-2/HO-1 pathway.

DL-α-Tocopherol acetate-¹³C₄,d₆ is the deuterium and ¹³C labeled DL-α-Tocopherol acetate. DL-α-Tocopherol acetate is a vitamin E derivative which is often included in the formulations of enteral nutrition.

Niacin-¹⁵N,¹³C₃ is the ¹³C and ¹⁵N labeled Niacin. Niacin (Vitamin B3) is an orally active water-soluble B3 vitamin that is an essential nutrient for humans. Niacin (Vitamin B3) plays a key role in energy metabolism, cell signaling cascades regulating gene expression and apoptosis. Niacin (Vitamin B3) is also used in the study of cardiovascular diseases.

Calcitriol-d₃ is the deuterium labeled Calcitriol. Calcitriol is the most active metabolite of vitamin D and also a vitamin D receptor (VDR) agonist.

Folic acid-¹⁵N,¹³C₅ is the ¹³C₅ and ¹⁵N labeled Folic acid (HY-16637).

L-Ascorbic acid-¹³C-4 is the ¹³C labeled L-Ascorbic acid. L-Ascorbic acid (L-Ascorbate), an electron donor, is an endogenous antioxidant agent. L-Ascorbic acid inhibits selectively Cav3.2 channels with an IC50 of 6.5 μM. L-Ascorbic acid is also a collag
