Oligonucleotides damaged with carcinogenic aromatic amines at the C8- and N6-position of 2'-deoxyadenosine.
The synthesis of C8- and N(6)-adducts of 2'- deoxyadenosine with carcinogenic aromatic amines is described. Furthermore, the adducts were converted into their corresponding phosphoramidites. These were applied to solid phase DNA synthesis to obtain the site-specifically modified oligonucleotides that were characterized and investigated regarding melting temperature, circular dichroism spectra and in some cases by enzymatic degradation assays.
