摘要
Phosphorothioate modification of oligonucleotides is one of the most promising chemical modifications in nucleic acid therapeutics. Structurally similar 5'-thio or phosphorothiolate-modified nucleotides, in which the 5'bridging oxygen atom is replaced with a sulfur atom, are attracting attention and gaining importance in oligonucleotide- based research. In our present study, we synthesized 5'-thio-2', 4'-BNA/LNA monomers bearing thymine or 5-methylcytosine nucleobase. The 5'-thio-2', 4'-BNA/LNA monomers were successfully incorporated into target oligonucleotides, and their nuclease stability and binding affinity with complementary strands were evaluated.
