The present invention provides 2-aminopyridine and 2-pyridone C-nucleosides and oligonucleotides containing the subject nucleosides. The nucleosides are useful in the preparation of the subject oligonucleotides. The oligonucleotides are useful in oligonucleotide-based diagnosis and separation through triplex binding.
                            本发明提供了2-
氨基吡啶和2-
吡啶酮C-核苷和含有该核苷的寡核苷酸。该核苷在制备该寡核苷酸中非常有用。该寡核苷酸在基于寡核苷酸的诊断和三股结合分离中非常有用。
