1,4-Naphthoquinone

1,4-Dihydro-1,4-diketonaphthalene

C10H6O2 (158.0368)


1,4-naphtoquinone, also known as 1,4-naphthalenedione or 1,4-dihydro-1,4-diketonaphthalene, is a member of the class of 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). 1,4-naphtoquinone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 1,4-naphtoquinone can be synthesized from naphthalene. 1,4-naphtoquinone is also a parent compound for other transformation products, including but not limited to, 2,3-dimethoxynaphthalene-1,4-dione, alisiaquinone A, and 1,4-naphthoquinone-2-carboxylic acid. 1,4-naphtoquinone can be found in liquor, which makes 1,4-naphtoquinone a potential biomarker for the consumption of this food product. 1,4-naphtoquinone is a non-carcinogenic (not listed by IARC) potentially toxic compound. CONFIDENCE standard compound; INTERNAL_ID 18 1,4-Naphthoquinone is a potential pharmacophore for inhibition of both MAO (monoamine oxidase) and DNA topoisomerase activities, this latter associated with antitumor activity[1].

Menadione

2-methylnaphthalene-1,4-dione

C11H8O2 (172.0524)


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. -- Pubchem; 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. 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. Moreover, menadione supplements have been banned by the FDA because of their high toxicity. It is sometimes called vitamin K3, although derivatives of naphthoquinone without the sidechain in the 3-position cannot exert all the functions of the K vitamins. 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. -- Wikipedia.

Atovaquone is only found in individuals that have used or taken this drug. It is a hydroxynaphthoquinone that has antimicrobial activity and is being used in antimalarial protocols. [PubChem]Atovaquone is a hydroxy- 1, 4- naphthoquinone, an analog of ubiquinone, with antipneumocystis activity. The mechanism of action against Pneumocystis carinii has not been fully elucidated. In Plasmodium species, the site of action appears to be the cytochrome bc1 complex (Complex III). Several metabolic enzymes are linked to the mitochondrial electron transport chain via ubiquinone. Inhibition of electron transport by atovaquone will result in indirect inhibition of these enzymes. The ultimate metabolic effects of such blockade may include inhibition of nucleic acid and ATP synthesis. Atovaquone also has been shown to have good in vitro activity against Toxoplasma gondii.
