Abstract

The possibility that the amounts of r-7,t-8-dihydroxy-t-9,10-oxy-7,8,9,10-tetrahydrobenzo[a]pyrene- deoxyguanosine (anti-BaP diol epoxide-dGuo) and r-7,t-8-dihydroxy-c-9,10-oxy-7,8,9,10-tetrahydrobenzo[a]pyrene- deoxyguanosine (syn-BaP diol epoxide-dGuo) may vary in human lymphocyte cultures from different donors was investigated by comparing DNA adducts formed after treatment with [G-3H]benzo[a]-pyrene (4 microM) for 24 h. In most cases, greater than 50% of the DNA adducts were derived from r-7,t-8-dihydroxy-c-9,10-oxy-7,8,9,10-tetrahydrobenzo[a]pyrene (syn-BaP diol epoxide).
