Description

Menadione, also known as vitamin K3 or aquinone, belongs to the class of organic compounds known as naphthoquinones. Naphthoquinones are compounds containing a naphthohydroquinone moiety, which consists of a benzene ring linearly fused to a bezene-1,4-dione (quinone). Large doses of menadione have been reported to cause adverse outcomes including hemolytic anemia due to G6PD deficiency, neonatal brain or liver damage, or neonatal death in some cases. Menadione is an extremely weak basic (essentially neutral) compound (based on its pKa). Menadione exists in all living organisms, ranging from bacteria to humans. In humans, menadione is involved in doxorubicin metabolism pathway. Outside of the human body, Menadione has been detected, but not quantified in, several different foods, such as wax gourds, garden rhubarbs, common buckwheats, chinese chives, and figs. This could make menadione a potential biomarker for the consumption of these foods. Menadione is a vitamin precursor of K2 which utilizes alkylation in the liver to yield menaquinones (MK-n, n=1-13; K2 vitamers), and hence, is better classified as a provitamin. Menadione is a potentially toxic compound. Moreover, menadione supplements have been banned by the FDA because of their high toxicity. Large doses have also been reported to cause brain damage. 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. It was first documented in 1961 (PMID: 13779073). Despite the fact that it can serve as a precursor to various types of vitamin K, menadione is generally not used as a nutritional supplement (PMID: 28166217) (PMID: 1650428) (PMID: 15052609) (PMID: 16469140).
