  Synthesis, Incorporation into Triplex-Forming Oligonucleotide, and Binding Properties of a Novel 2‘-Deoxy-C-Nucleoside Featuring a 6-(Thiazolyl-5)benzimidazole Nucleobase

  摘要：

  6-(Thiazolyl-5)benzimidazole (B-1) was designed as a novel nucleobase for the specific recognition of an inverted A(.)T base pair in a triple helix motif. It was successfully incorporated into an 18-mer triplex-forming oligonucleotide (TFO) using the 2'-deoxy-C-nucleoside phosphoramidite 16. The triple helix binding properties of the modified TFO were examined by means of thermal denaturation experiments targeting an oligopyrimidine-oligopurine 26-mer DNA duplex containing an A-T base pair inversion.
