Synthesis and triplex-forming properties of oligonucleotides containing thio-substituted C-nucleoside 4-thiopseudoisocytidine
摘要:
We synthesized the 3'-phosphoramidite building block of 4-thiopseudoisocytidine (s(4)psi iC) and incorporated it into triplex-forming oligonucleotides (TF05). The results of thermal denaturation of triplexes incorporating s(4)psi iC showed that s(4)psi iC could be used as a nucleoside component of TFOs to increase the thermal stability of triplexes at pH 7.
