Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic substances that are mainly generated during heating in food; therefore, the European Union (EU) has regulated the amount of benzo[a]pyrene and PAH4 in various types of food. In addition, the Scientific Committee on Food
The three-dimensional structure of the product of the reaction of a diol epoxide of the carcinogen 5-methylchrysene with methanol has been determined by an X-ray diffraction analysis. The diol epoxide used to obtain this compound contains a stereochemically hindered bay

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
The distribution of hydrocarbon-DNA adducts through the supF gene in plasmid pS189 was examined using the polymerase arrest assay. For three hydrocarbon dihydrodiol epoxides, derived from 5-methylchrysene, 7-methylbenz[a]anthracene, and benzo[a]pyrene, that exhibit a preference for reaction with guanine residues in

In previous studies, we have observed unexpected structure-tumorigenicity relationships among the dimethylchrysenes. Thus, 5,6-dimethylchrysene and 5,7-dimethylchrysene were only weakly tumorigenic and were significantly less active than 5-methylchrysene. These results were surprising in view of the known route of metabolic activation
