摘要: 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.
