  Pteridine Nucleosides—New Versatile Building Blocks in Oligonucleotide Synthesis

  摘要：

  Chemical syntheses of 1-(2-deoxy-beta-D-ribofuranosyl)lumazines and isopterins as well as 8-(2-deoxy-beta-D-ribofuranosyl)-4-amino-7(8H)pteridones and -isoxanthopterins have been developed to make the structural analogs of the naturally occurring 2'-deoxyribonucleosides in the pteridine series available. The corresponding phosphoramidites have been used in machine-aided solid-support syntheses leading to new types of fluorescence labeled oligonucleotides. The effects of the various fluorophors on duplex formation and as labels for enzyme reactions is demonstrated.

  3′-(2-cyanoethyI diisopropylphosphoramidites) 34–39 which function as monomeric building block in oligonucleotide syntheses as well as into the 3′-(hydrogen succinates) 40–45 which can be used for coupling with the solid-support material. A series of lumazine-modified oligonucleotides were synthesized and the influence of the new nucleobases on the stability of duplex formation studied by measuring the Tm values
