title: Synthesis of DNA strands site-specifically damaged by c8-arylamine purine adducts and effects on various DNA polymerases.
abstract: C8-Arylamine-dG and C8-arylamine-dA adducts have been prepared using palladium cross-coupling chemistry. These adducts were subsequently converted into the corresponding 5'-O-DMTr-C8-arylamine-3'-O-phosphoramidites and then used for the automated synthesis of different site-specifically modified oligonucleotides. These "damaged" oligonucleotides have been characterized by ESI-MS, UV thermal stability assays, and circular dichroism, and they have been used in EcoRI assays as well as in primer extension studies using various DNA polymerases.
