N-nitrosodimethylamine (NDMA), also known as dimethylnitrosamine, is a semivolatile, organic chemical that forms in both industrial and natural processes. It is not currently produced in pure form or used commercially in the United States, except for research purposes. It was formerly used in the production of rocket fuels and was used as an antioxidant, additive for lubricants, and a softening agent for copolymers. Evidence suggests that NDMA requires metabolic activation to exert its toxic and carcinogenic effects. NDMA undergoes oxidative demethylation which produces reactive intermediates. This causes methylation of DNA and mRNA leading to its ultimate carcinogenic and mutagenic effects. Subsequently, a number of investigators have linked the appearance of methylated DNA adducts derived from NDMA with the appearance of tumors. Both the ability of a tissue to metabolize NDMA and thereby generate DNA adducts, and the ability of the tissue to repair DNA adducts appear to play important roles in the mechanism of NDMA carcinogenicity.
