  Synthesis and Biophysical and Biological Properties of Oligonucleotides Containing 2-Aza-2'-Deoxyinosine

  摘要：

  The preparation of oligonucleotides containing 2-aza-2'-deoxyinosine is described. Protection of the 2-azahypoxanthine moiety with the photolabile 2-nitrobenzyl group enabled us to obtain the phosphoramidite derivative and oligonucleotides containing protected 2-aza-2'-deoxyinosine. After purification, photolysis of the oligonucleotides containing the protected analogue provided the desired oligonucleotides in good yields. Melting curves of duplexes containing 2-azahypoxanthine paired with the four natural bases at pH 6 and pH 8 proved that 2-azahypoxanthine base pairs were less stable than perfectly matched duplexes but showed little variation among different bases.
