Carcinogenicity in rats of a mutagenic compound, 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline.

abstract：:A family of 2-amino-N-methylimidazoazaarene (AIA) mutagens are produced in meats by cooking, and are of concern as potential carcinogens in the human diet. These are potent genotoxins in bacterial mutation assays, but are present only in trace quantities in cooked foods. Conventional analytical chemistry methods have ...
