Abstract excerpt
Aromatic chemical carcinogens can undergo enzymatic transformations to produce a range of electrophilic species that attach covalently to the C8-site of 2'-deoxyguanosine (dG) to afford C8-dG adducts. The most studied C8-dG adducts are formed from arylamines and contain a N-linkage separating the dG from the C8-aryl moiety. Other carcinogenic species result in direct aryl ring attachment to the dG moiety,...
