ABSTRACT
Peptide nucleic acids containing thymidine and 2-aminopyridine (M) nucleobases form stable and sequence-selective triple helices with double-stranded RNA at physiologically relevant conditions. The M-modified PNA showed unique RNA selectivity by having two orders of magnitude higher affinity for the double-stranded RNAs than for the same DNA sequences.
