  Replacement of the phosphodiester linkage in oligonucleotides by an amide: Effect of backbone length on duplex stability with RNA complement

  摘要：

  Five dimers containing amide linkages instead of the natural phosphodiester linkage were synthesized and incorporated into oligonucleotides. The length of the amide backbone was varied. The hybridization properties of the modified oligonucleotides with RNA complements and their conformational analysis are described and compared to previously reported amide containing oligonucleotides. In addition, the synthesis of a thioamide phosphoramidite dimer is reported. (C) 1997, Elsevier Science Ltd.

  Comparison of two amides as backbone replacement of the phosphodiester linkage in oligodeoxynucleotides

  摘要：

  The two isomeric amide modifications 1 and 2 show similar effects on the melting temperature of RNA/DNA duplexes, when they replace the natural phosphodiester linkage in the DNA strand. The synthesis of the amide dimer 1 is presented.
