Patterns of resistance to exonuclease digestion of oligonucleotides containing polycyclic aromatic hydrocarbon diol epoxide adducts at N6 of deoxyadenosine.


The effect of adduct stereochemistry on the susceptibility to hydrolysis by snake venom (VPD) and bovine spleen (SPD) phosphodiesterases was investigated with short deoxyoligonucleotides containing defined adducts derived from alkylation of the exocyclic 6-amino group of dA by polycyclic aromatic hydrocarbon diol epoxides (DEs). In accordance with several… (More)
