title: Synthesis of a peptide nucleic acid oligomer with pyrimido[4,5-d]pyrimidine-2,4,5,7-(1H,3H,6H,8H)-tetraone as a nucleobase.
abstract: A peptide nucleic acid (PNA) oligomer containing pyrimido[4,5-d]pyrimidine-2,4,5,7-(1H,3H,6H,8H)-tetraone (PPT) as a nucleobase, which is expected to serve as a universal base, was synthesized.
