The present disclosure provides tricyclic nucleosides and oligomeric compounds prepared therefrom. The tricyclic nucleosides each have a tricyclic ribosyl sugar moiety wherein a bridge between the 2' and 4' ribosyl ring carbon atoms further comprises a fused carbocyclic or heterocyclic ring. The tricyclic nucleosides are expected to be useful for enhancing properties of oligomeric compounds including for example binding affinity and nuclease resistance.
本公开提供了由此制备的
三环核苷和寡聚化合物。这些
三环核苷每个都具有一个
三环核糖糖基,其中2'和4'
核糖环碳原子之间的桥进一步包括一个融合的碳环或杂环。预计这些
三环核苷对增强寡聚化合物的性质将会有用,例如结合亲和力和
核酸酶抗性。
