Hydroxyl ion attack on aflatoxin B1 (AFB1)-adducted DNA followed by acid hydrolysis releases two AFB1 derivatives, 8,9-dihydro-8-(2,6-diamino-4-oxo-3,4-dihydropyrimid-5-yl formamido) 9-hydroxy AFB1 (major compound) and 8, 9-dihydro-8-(2-ammino-6-formamido-4-oxo-3,4dihydropyrimid-5-yl amino)9-hydroxy AFB1. The minor compound converts into the major isomer in aqueous dimethylsulphoxide.
