摘要
As technologies using RNA or DNA have been developed, various chemical modifications of nucleosides have been attempted to increase the stability of oligonucleotides. Since it is known that 2 '-OMe-modification greatly contributes to increasing the stability of oligonucleotides, we added 2 '-OMe to our previously developed 4 '-selenonucleoside and 5 '-homo-4 '-selenonucleoside as the modified monomers for oligonucleotide: 2 '-methoxy-4 '-selenouridine (2 '-OMe-4 '-Se-U) and 5 '-homo-2 '-methoxy-4 '-selenouridine (5 '-homo-2 '-OMe-4 '-Se-U). We synthesized oligonucleotides containing the chemically modified 4 '-selenouridine and evaluated their thermal stability and nuclease resistance. In conclusion, the nuclease stability of the oligonucleotide containing 5 '-homo-2 '-OMe-4 '-selenouridine increased while its thermal stability decreased.
