Metabolite Identification

Common Name

1,2-Naphthoquinone

Description

1,2-Naphthoquinone, also known as 1,2-naphthalenedione, 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). 1,2-Naphthoquinone is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on 1,2-Naphthoquinone. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-naphthoquinone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Naphthoquinone is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

Enzyme Details

1. Quinone oxidoreductase

General function:: Involved in zinc ion binding
Specific function:: Does not have alcohol dehydrogenase activity. Binds NADP and acts through a one-electron transfer process. Orthoquinones, such as 1,2-naphthoquinone or 9,10-phenanthrenequinone, are the best substrates (in vitro). May act in the detoxification of xenobiotics. Interacts with (AU)-rich elements (ARE) in the 3'-UTR of target mRNA species. Enhances the stability of mRNA coding for BCL2. NADPH binding interferes with mRNA binding.
Gene Name:: CRYZ
Uniprot ID:: Q08257
Molecular weight:: 35206.36

Enzyme Details

2. Aflatoxin B1 aldehyde reductase member 2

General function:: Energy production and conversion
Specific function:: Catalyzes the NADPH-dependent reduction of succinic semialdehyde to gamma-hydroxybutyrate. May have an important role in producing the neuromodulator gamma-hydroxybutyrate (GHB). Has broad substrate specificity. Has NADPH-dependent aldehyde reductase activity towards 2-carboxybenzaldehyde, 2-nitrobenzaldehyde and pyridine-2-aldehyde (in vitro). Can reduce 1,2-naphthoquinone and 9,10-phenanthrenequinone (in vitro). Can reduce the dialdehyde protein-binding form of aflatoxin B1 (AFB1) to the non-binding AFB1 dialcohol. May be involved in protection of liver against the toxic and carcinogenic effects of AFB1, a potent hepatocarcinogen.
Gene Name:: AKR7A2
