A novel nucleic acid adduct of the carcinogen 4-nitroquinoline 1-oxide, N4-(guanosin-7-yl)-4-aminoquinoline 1-oxide, was separated and identified after RNA was treated with activated 4-hydroxyaminoquinoline 1-oxide. This is the first report of a 7-arylaminated guanine adduct produced by arylaminating carcinogens.
