General description

1,2-Naphthoquinone is one of the major metabolite of naphthalene, which is responsible for the cytotoxicity and genotoxicity associated with it. 1,2-Naphthoquinone is an atmospheric contaminant. It causes the contraction of trachea smooth muscles in guinea pig through the activation of epidermal growth factor receptor. 1,2-Naphthoquinone has been reported as an environmental quinone in diesel exhaust particles (DEP) and atmospheric particulate matter.

Application

1,2-Naphthoquinone was employed as mediator during electrochemical mapping of redox activity in normal human breast (MCF-10A) cells by scanning electrochemical microscopy (SECM).

Electrochemical methods have been widely used to monitor physiologically important molecules in biological systems. This report describes the first application of the scanning electrochemical microscope (SECM) to probe the redox activity of individual living cells. The possibilities of measuring the

Naphthalene-1,2-oxide (NPO), 1,2-naphthoquinone (1,2-NPQ) and 1,4-naphthoquinone (1,4-NPQ) are the major metabolites of naphthalene that are thought to be responsible for the cytotoxicity and genotoxicity of this chemical. We measured cysteinyl adducts of these metabolites in hemoglobin (Hb) and albumin (Alb)

This study was designed to characterize naphthalene metabolism in Polaromonas naphthalenivorans CJ2. Comparisons were completed using two archetypal naphthalene-degrading bacteria: Pseudomonas putida NCIB 9816-4 and Ralstonia sp. strain U2, representative of the catechol and gentisate pathways, respectively. Strain CJ2 carries
