menadione

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.

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.

Menadione sodium bisulfite hydrate (Standard) is a reference standard of Menadione sodium bisulfite hydrate intended for quantitative analysis, quality control, and related biochemical research applications.

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

AK-135 is a derivative of 1,4-naphthoquinone (Menadione). AK-135 has been shown to restore the electron flow in defective respiratory chain (hypoxia or rotenone) systems more effectively than Menadione.

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.

Dihydroisotanshinone I is a natural product isolated from the dried roots of Salvia miltiorrhiza, a traditional Chinese medicine, and exhibits various biological activities. Dihydroisotanshinone I alleviates menadione-induced liver injury through antioxidant effects such as scavenging free radicals and inhibiting lipid peroxidation; it also inhibits the migration of prostate cancer cells and induces cancer cell apoptosis.

5-Carboxy-2'-deoxyuridine is a metabolite of Trifluridine. It is produced as an oxidized methyl derivative of thymidine and can be formed through a thionaphthene (menadione)-mediated photosensitization of thymidine.
