<p>A bicyclic nucleoside derivative, wherein an intranucleoside ring locks the ring conformation of the nucleoside, is termed an LNA - a Locked Nucleic Acid. LNAs of the xylo-configuration, considered useful as therapeutic agents, diagnostic agents and useful for the formation of oligonucleotides, have been prepared. These oligonucleotides are also useful as a therapeutic and in diagnostic fields. Furthermore, oligonucleotides comprising LNAs of the xylo-configuration are useful for high-affinity targeting of complementary single stranded and double stranded DNA and RNA and have interesting activity with regards to specificity and affinity to oligonucleotides.</p> |
