RESUMO
A new modified polydeoxynucleotide, a copolymer of nucleotides of 2'-deoxyadenosine and the very efficacious anti-herpesvirus agent (E)-5-(2-bromovinyl)-2'-deoxyuridine was synthesized with E. coli DNA polymerase I enzyme. It is characterized by its physical (absorption and circular dichroism spectra, thermal transition, sedimentation analysis) and bioorganic (template activity, stability) properties. Compared to poly [d(A-T)], the modified polydeoxynucleotide had a lower thermal stability but exhibited higher stability against DNases and higher template activity for DNA synthesis. Template activity for RNA synthesis of this template was, however, poor and extent of AMP and UMP incorporation was limited as well.
