Disclosed are novel bifunctional nucleoside analogs and oligonucleosides of 3-4 bases (trimers and tetramers) and longer containing at least two consecutive internucleoside linkages of two carbon-one nitrogen atom or two carbon-one oxygen atom (3'-NCC-5', 3'-CNC-5', 3'-OCC-5') internucleoside linkages. The bifunctional nucleosides are useful for preparing the trimers and tetramers, which, in turn, are useful, together with the nucleosides, in preparing oligonucleosides as well as chimeric oligonucleotide analogs, preferably antisense oligonucleosides and oligonucleotide analogs, of 6 to about 60 bases having at least two consecutive internucleoside linkages of two carbon atoms and one nitrogen atom or 2 carbon atoms and one oxygen atom in the oligonucleoside backbone.
揭示了一种新型的双功能核苷类似物和含有至少两个连续的核苷酸连接的3-4个碱基(三聚体和四聚体)及更长的寡核苷酸。这些连接是二碳-一氮原子或二碳-一氧原子(3'-NCC-5',3'-CNC-5',3'-OCC-5')之间的核苷酸连接。这些双功能核苷类似物可用于制备三聚体和四聚体,这些三聚体和四聚体与核苷酸一起可用于制备寡核苷酸以及嵌合寡核苷酸类似物,最好是6至约60个碱基的具有至少两个连续的二碳原子和一个氮原子或两个碳原子和一个氧原子的核苷酸骨架的反义寡核苷酸和寡核苷酸类似物。
