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).

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
