  摘要：

  For development of ideal antisense and antigene molecules, various chemical modifications of oligonucleotides have been studied. However, despite their importance. there is only limited information available on the tripler-forming ability of the conformationally restricted or locked oligonucleotides. We report herein that 2'-O,4'-C-methylene bridged nucleic acid (2',4'-BNA) modification of tripler-forming oligonucleotide: (TFO) significantly enhances the binding affinity towards target dsDNA. On T, measurements. the triplex with the 2',4'-BNA oligonucleotides were found to be stabilized with DeltaT(m)/modification of +4.3 to + 5 degreesC at pH 6.6 compared to the triplexes with the unmodified oligonucleotide. By means of gel-retardation assay, the binding constant of the 2'.4'-BNA oligonucleotide at pH 7.0 was at least 300-fold higher than that of the natural oligonucleotide. In addition, the 2',4'-BNA oligonucleotide clearly showed the inhibition of the NF-K-B transcription factor (p50)-target dsDNA binding by forming a stable tripler at pH 7.0.

  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
