vitamin k 3

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.

Menadione bisulfite sodium (Vitamin K3 sodium bisulfite) is used clinically in China to treat hemorrhagic diseases caused by vitamin K deficiency and globally as a vitamin K supplement.

Vitamin K3-d3 is a deuterated compound of Vitamin K3. Vitamin K3 has a CAS number of 58-27-5. Menadione 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.

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.

Menadione (Standard) is the standard substance of Menadione, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. 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.

Vitamin K3-D3 (Standard) is a reference standard of Vitamin K3-D3 intended for quantitative analysis, quality control, and related biochemical research applications. Vitamin K3-d3 is a deuterated compound of Vitamin K3. Vitamin K3 has a CAS number of 58-27-5. Menadione 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.

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.

Betrixaban maleate is a non-vitamin K oral anticoagulant whose action is driven by the competitive and reversible inhibition of the factor Xa.

Betrixaban (PRT054021) is a non-vitamin K oral anticoagulant whose action is driven by the competitive and reversible inhibition of the factor Xa [1]. It was selected among all lead compounds due to its low hERG channel affinity while sustaining its factor Xa inhibition capacity [3]. Betrixaban, now developed by Portola Pharmaceuticals Inc., is prescribed as a venous thromboembolism (VTE) prophylactic for adult patients with moderate to severe restricted motility or with other risks for VTE [2]. VTE can be manifested as deep vein thrombosis or pulmonary embolism and it is a leading cause of preventable death in hospitalized patients [4].

3-Keto Sphinganine (d12:0) is a short-chain analog of 3-keto sphinganine (d18:0), which typically possesses a C18 chain length. The latter is a lyso-sphingolipid synthesized through the condensation of L-serine and palmitoyl-CoA mediated by the enzyme serine palmitoyl transferase (SPT). A deficiency in Vitamin K deactivates SPT, leading to a reduced synthesis of 3-keto sphinganine among other sphingolipids. [Matreya, LLC. Catalog No. 1893]
