High-affinity RNA mimicking binding of 2',4'-BNANC towards complementary strands: a comparative study with 2',4'-BNA/LNA
High-affinity RNA mimicking binding of 2',4'-BNANC towards complementary strands: a comparative study with 2',4'-BNA/LNA.2'
2',4'-BNA(NC), a bridged nucleic acid analogue, which was designed and synthesized in our laboratory, showed very high binding affinity towards complementary RNA and DNA strands. Its duplex-forming ability towards a single-stranded RNA was similar to or slightly higher than that of 2',4'-BNA and the overall triplex-forming ability against a double-stranded DNA was also better than that of 2',4'-BNA. 2',4'-BNA(NC) exhibited higher RNA selectivity than 2',4'-BNA.
