Photoproducts from DNA pyrimidine bases and polycyclic aromatic hydrocarbons.
The major photoproduct formed between benzo[a]pyrene and thymine is identified as 1-(benzo[a]pyren-6-yl)-thymine by means of spectroscopic analysis and isotopic syntheses. Irradiation of 1-methylcytosine hydrochloride and anthracene gives two isolable photoproducts of which one is assigned the structure 5-(anthracen-9-yl)-1-methylcytosine.
