Structural highlights
Publication Abstract from PubMedA sulfonamide-bridged nucleic acid without an N-substituent (SuNA[NH]) was successfully synthesized. A comparison of the SuNA[NMe]- and SuNA[NH]-modified oligonucleotides revealed that the duplex-forming abilities of the SuNA[NMe]-modified oligonucleotides with complementary DNA and RNA were higher than those of the SuNA[NH]-modified oligonucleotides. The crystal structures of DNA duplexes containing a SuNA[NR] revealed that the helical structures of the two duplexes and hydration patterns around the bridge moiety were different. These results provide insights into hydration patterns and rationale for the high RNA affinity of SuNA-modified oligonucleotides.
