5'-SUBSTITUTED BICYCLIC NUCLEOSIDES AND OLIGOMERIC COMPOUNDS PREPARED THEREFROM

摘要

Provided herein are novel 5'-(S)-CH3 substituted bicyclic nucleosides, oligomeric compounds prepared therefrom and methods of using the oligomeric compounds. More particularly, the furanose ring of each of the novel 5'-(S)-CH3 substituted bicyclic nucleosides includes a 2' to 4' bridging group. The 5'-(S)-CH3 substituted bicyclic nucleosides are expected to be useful for enhancing one or more properties of the oligomeric compounds they are incorporated into such as for example increasing the binding affinity. In certain embodiments, the oligomeric compounds provided herein hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.
