摘要

6-(Thiazolyl-5) benzimidazole (B t) 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⊙ ...
