Spectroscopic characterization of syn-5-methylchrysene 1,2-dihydrodiol 3,4-epoxide-deoxyribonucleoside adducts.


Eight deoxyribonucleoside adducts formed from reactions of syn-5-methylchrysene 1,2-dihydrodiol 3,4-epoxide with DNA or with nucleotides were characterized spectroscopically. The adducts arose from both cis and trans opening of the epoxide ring at C4 by the amino group of either deoxyadenosine or deoxyguanosine residues. NMR data indicated that the… (More)
