  Triazolyl Donor/Acceptor Chromophore Decorated Unnatural Nucleosides and Oligonucleotides with Duplex Stability Comparable to That of a Natural Adenine/Thymine Pair

  摘要：

  We report the design and synthesis of triazolyl donor/acceptor unnatural nucleosides via click chemistry and studies on the duplex stabilization of DNA containing two such new nucleosides. The observed duplex stabilization among the self-pair/heteropair has been found to be comparable to that of a natural A/T pair. Our observations on the comparable duplex stabilization has been explained on the basis of possible pi-pi stacking and/or charge transfer interactions between the pairing partners. The evidence of ground-state charge transfer complexation came from the UV-vis spectra and the static quenching of fluorescence in a heteropair. We have also exploited one of our unnatural DNAs in stabilizing abasic DNA.

  A better than reported abasic duplex stabilization was achieved with the novel triazolylphenanthrene nucleoside TPhenBDo. The large surface area, polarizability and strong stacking propensity of triazolylphenanthrene play a major role in the thermal stabilization of the TPhenBDo–Φ duplex comparable to that of a natural A–T pair via a strong intercalative stacking interaction.

  使用新型三唑基苯并蒽核苷TPhenBDo，获得了比报道更好的无碱二聚体稳定性。三唑基苯并蒽具有较大的表面积、极化性和强叠加倾向，这些因素在TPhenBDo–Φ二聚体的热稳定性中起着主要作用，其稳定性可与自然的A–T对相媲美，得益于强的插层叠加相互作用。
