  Diisopropylsilyl-linked oligonucleotide analogs: solid-phase synthesis and physicochemical properties

  摘要：

  A novel synthetic method has been developed for efficient preparation of silyl-linked oligodeoxyribonucleotide analogs. The method allows, for the first time, automated solid-phase synthesis of long oligomers uniformly linked with the silyl internucleoside bridge. Synthesis of a thymidylate decanucleotide analog (14) illustrates this advance. The preparation of chimeric oligodeoxyribonucleotides containing single or multiple diisopropylsilyl backbone structures along with natural phosphodiester links is also described. These mixed backbone DNA strands were soluble and chemically stable in buffered aqueous solutions, as required for physicochemical study. These oligomers demonstrated excellent stability toward cleavage by 3'-exonuclease and good binding affinity with complementary oligonucleotides.
