The novel base 4-3-benzamidophenylimidazole was designed, synthesized and incorporated within a pyrimidine oligonucleotide and shown to recognize pyrimidine purine base pairs over purine pyrimidine base pairs. Such specificity allows binding by triple helix formation at an 18 base pairs site in simian virus 40 DNA containing all four base pairs at physiologically relevant conditions.
