    DNA triplex structures are stabilized by the incorporation of 3′-endo blocked pyrimidine nucleosides in the hoogsteen strand
    摘要:
    A short route to pyrimidine locked nucleosides has been developed for their incorporation in tripler forming oligonucleotides (TFO). Compared to oligonucleotides built with standard nucleosides, the modified TFOs containing 3'-endo blocked residues formed, with their corresponding DNA duplexes, more stable triple helix systems, an effect which might be ascribed to the 3'-endo pucker of the modified nucleoside residues.

    In order to develop novel 2′,5′-linked oligonucleotide analogues aimed for antivirus reagents and antisense/antigene oligonucleotides, novel nucleoside analogues, 3′-O,4′-C-methyleneribonucleosides (3′,4′-BNA monomers) were synthesized via two synthetic routes. The first route starting from uridine utilized a regioselective ring-closure reaction of the 4′-C-(p-toluenesulfonyl)oxymethyluridine derivative
