The present invention provides compounds having a chelating moiety and an oligonucleotide sequence wherein the oligonucleotide includes one or more modified nucleobases, such as hydroxynucleobases. The disclosed compounds are suitable for antisense therapy. The chelating moiety can be complexed to an ion of a lanthanide metal. These compounds are efficient translation inhibitors of nucleic acids and have increased binding affinity for target nucleic acids. The invention also includes compositions and methods of using these compositions as antisense therapy.
本发明提供了具有螯合基团和寡核苷酸序列的化合物,其中寡核苷酸包括一个或多个修饰的核碱基,例如羟基核碱基。所述化合物适用于反义疗法。螯合基团可以与
镧系
金属离子形成络合物。这些化合物是核酸的高效翻译
抑制剂,并且对目标核酸具有增强的结合亲和力。本发明还包括使用这些组合物作为反义疗法的组合物和方法。
