We have recently designed and synthesized a novel bridged nucleic acid analogue 2',4'-BNANC, bearing an N-O bridged structure, which furnished both higher duplex and triplex-forming abilities and sequence selectivity towards complementary RNA and/or DNA, respectively, and showed excellent resistance against nuclease degradation. Duplex and triplex-forming abilities were slightly higher or similar to those of 2',4'-BNA and nuclease resistance was as high as that of S-oligo.
