vitamin k

Vitamin K (Kephton) has blood coagulation action and is important for coagulation factors, matrix-Gla protein, and osteocalcin.

Menadione (Vitamin K3) is a synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo.

Coumarin is a chemical compound/poison found in many plants, notably in high concentration in the tonka bean, woodruff, and bison grass. It has clinical value as the precursor for several anticoagulants, notably warfarin.

Warfarin (Coumafene) is a vitamin K antagonist, and it works by blocking the action of vitamin K, which is necessary for the synthesis of clotting factors in the liver. Warfarin blocks the action of vitamin K by inhibiting the enzyme gamma-glutamyl carboxylase, which is responsible for the carboxylation of glutamate residues in the clotting factors. This prevents the production of functional clotting factors, leading to an anticoagulant effect.

Chlorindione (chlophenadione) is a vitamin K antagonist, a potent anticoagulant compound.

Coumetarol (Dicumoxane) is a vitamin K antagonist and an oral anticoagulant that can be used to study arterial thrombotic occlusion.

During hypoxia in rats, levels of α-tocopherylquinon have been found to rise. alpha-Tocopherolquinone (Metarene) is reported to downregulate the respiratory activity of mitochondria. alpha-Tocopherolquinone has also displayed antioxidant activities after it is reduced to tocopherylhydroquinone.

Phenprocoumon is an antagonist of vitamin K(IC50:1 μM).

Acenocoumarol is a Vitamin K antagonist and used as an anticoagulant.

Cis-Vitamin K1 is an endogenous metabolite of Vitamin K [1].

Vitamin K5 (Synkamin), a photosensitizer and antimicrobial agent, serves as a specific PKM2 inhibitor, demonstrating IC 50 values of 28, 191, and 120 μM against PKM2, PKM1, and PKL, respectively. It induces apoptosis in colon 26 cells and is utilized in infection and cancer research. Additionally, Vitamin K5 finds application as a preservative in pharmaceuticals, foods, and beverages [1] [2] [3].

Vitamin K1-D4 is a deuterated compound of Vitamin K1. Vitamin K1 (T1075) has a CAS number of 84-80-0. Vitamin K1 (T1075) (Phylloquinone) is a naturally-occurring vitamin. Vitamin K1 (T1075) is essential for blood clotting, bone and vascular metabolism.

Vitamin K1-D7 is a deuterated compound of Vitamin K1.

Vitamin K5 hydrochloride (Standard) is a reference standard for research and analysis in studies involving Vitamin K5 hydrochloride. Vitamin K5 (hydrochloride), a naphthoquinone compound, exhibits trichomonacidal activity in vitro and can be utilized for anti-infection research [1].

Vitamin K1-D7 (Standard) is a reference standard of Vitamin K1-D7 intended for quantitative analysis, quality control, and related biochemical research applications. Vitamin K1-d7 is a deuterated compound of Vitamin K1.

Vitamin K1-D4 (Standard) is a reference standard of Vitamin K1-D4 intended for quantitative analysis, quality control, and related biochemical research applications. Vitamin K1-d4 is a deuterated compound of Vitamin K1. Vitamin K1 has a CAS number of 84-80-0. Vitamin K1 (Phylloquinone) is a naturally-occurring vitamin. Vitamin K1 is essential for blood clotting, bone and vascular metabolism.

Vitamin K1 (Phylloquinone) a fat-soluble, naturally occurring vitamin with antihemorrhagic and prothrombogenic activity.

Vitamin K2 (Menatetrenone) is a menaquinone compound and form of vitamin K2 with potential antineoplastic activity. Menatetrenone may act by modulating the signaling of certain tyrosine kinases, thereby affecting several transcription factors including c-myc and c-fos. This agent inhibits tumor cell growth by inducing apoptosis and cell cycle arrest.

Vitamin K4 (Menadiol Diacetate) is a vitamin medicine for the treatment of blood coagulation disorders that caused by the lack of VK4.

Vitamin K1 2,3-epoxide (Phylloquinone oxide) is reduced to vitamin k and is involved in the vitamin k cycle.

Vitamin K3-D8 is a deuterated derivative of Vitamin K3, and Vitamin K3-D8, like Menadione (Vitamin K3), is a synthetic naphthoquinone lacking the isoprenoid side chain and intrinsic biological activity; however, Vitamin K3-D8 can be enzymatically converted into active Vitamin K2 (menaquinone) following in vivo alkylation, supporting research into vitamin K metabolism, biochemical labeling studies, and isotope-tracer investigations in metabolic and nutritional sciences.

Vitamin K1 2,3-epoxide (Standard) is a reference standard for research and analysis in studies involving Vitamin K1 2,3-epoxide. Vitamin K1 2,3-epoxide (Phylloquinone oxide) is reduced to vitamin k and is involved in the vitamin k cycle.

Vitamin K3-D8 (Standard) is a reference standard of Vitamin K3-D8 intended for quantitative analysis, quality control, and related biochemical research applications. Vitamin K3-d8 is a deuterated derivative of Vitamin K3, and Vitamin K3-d8, like Menadione (Vitamin K3), is a synthetic naphthoquinone lacking the isoprenoid side chain and intrinsic biological activity; however, Vitamin K3-d8 can be enzymatically converted into active Vitamin K2 (menaquinone) following in vivo alkylation, supporting research into vitamin K metabolism, biochemical labeling studies, and isotope-tracer investigations in metabolic and nutritional sciences.

Vitamin K5 hydrochloride is a photosensitizer and antimicrobial agent that functions as a specific inhibitor of pyruvate kinase M2 (PKM2), with IC50 values of 28 μM for PKM2, 191 μM for PKM1, and 120 μM for PKL. Vitamin K5 hydrochloride induces apoptosis in colon 26 cells, supporting its application in infection and cancer research as well as its practical use as a preservative in pharmaceutical, food, and beverage formulations.
