title: Synthesis and characterization of oligodeoxynucleotides containing the major DNA adducts formed by 1,6- and 1,8-dinitropyrene.
abstract: [reaction: see text] An efficient method for the synthesis of oligonucleotides containing a site-specific DNA adduct formed by the carcinogens 1,6- and 1, 8-dinitropyrene has been developed. Palladium-catalyzed amination provided a straightforward route for the synthesis of aminonitropyrenes which, following separation, were reduced to the nitrosonitropyrenes. The N-hydroxyaminonitropyrene, generated in situ from each nitrosonitropyrene, was used successfully to introduce the dinitropyrene-derived DNA adduct at a defined site in an oligonucleotide.
