Abstrakt: In order to expand the target sequence used in triplex DNA formation, seven novel nucleotide analogues were synthesized and incorporated into triplex-forming oligonucleotides by post-elongation modification approaches. Among them, GPB, equipped with a suitable restricted conformation of sugar and nucleobase moieties, was found to have the highest sequence-selectivity and affinity towards CG base pairs within double-stranded DNA.
