Oligonucleotides containing 2'-OMe-5-Me-U (2'-OMe-T), 2'-OMe-N-Ac-5-Me-C or 2'-OMe-I are particularly applicable to triplex and antisense studies using 2'-OMe-RNA. For example, the immune stimulatory activity of CpG containing oligonucleotides in which C or G was substituted with 2'-OMe ribonucleotides, 5-Me-dC, or 2'-OMe-5-Me-C has been studied alone and in combination with TLR agonists. (1)
When 2'-OMe residues are incorporated into triplex forming oligonucleotides (2) (TFOs), similar trends in nuclease resistance and triplex stability are seen as with duplexes.
Hence they have been used to develop TFOs for use as gene targeting reagents.(3) Triplex stability can be increased further with the incorporation of 2'-OMe-5-Me-U residues into the oligonucleotide (4) using 2'-OMe-5-Me-U. Interestingly, 2'-OMe-5-Me C can have the opposite effect and destabilise the triplex, yet is still more stable than a DNA and/or RNA triplex. Incorporation of both 2'-OMe-5-Me U and 2'-OMe-5-Me C enables fine tuning of the Tm of the resulting triplex.
