  Synthesis of Triple Helix Forming Oligonucleotides with a Stretched Phosphodiester Backbone

  摘要：

  Total synthesis of novel DMT-phosphoramidites of thymidine (11 and 15) and 2'-deoxyguanosine (8 and 20) have been accomplished. The utility of these modified building blocks in the preparation of triple helix forming oligodeoxyribonucleotides with a stretched phosphodiester backbone has been evaluated. It was found that the oligonucleotides with extended backbones were unable to enhance the binding to duplex targets containing CG or TA base pairs.
