  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.

  Synthesis of dendritic oligodeoxyribonucleotide analogs with nonionic diisopropylsilyl linkage

  摘要：

  Series of new dendritic oligodeoxyribonucleotide analogs with diisopropylsilyl linkage were prepared via liquid-phase synthesis. Dendron was employed as soluble support, which facilitated purification of the products by simple solvent precipitation. Sequences leading to the dendritic octamer 5'-TSiTSiTSiTSiTSiT-(Si)T(Si)T(S)2-3' (T8D(2)) were prepared and each isolated intermediate was characterized by NMR and mass spectrometry. The recognition properties of two complementary dendritic dinucleotide analogs of TSiTSiD2 (T2D2) and A(Si)A(Si)D(2) (A2D(2)) were also studied by NMR and FT-MS spectra in a nonaqueous aprotic environment (C) 2011 Elsevier Ltd.
