  The present invention relates to novel bicyclic and tricyclic nucleoside and nucleotide analogues as well as to oligonucleotides comprising such elements. The nucleotide analogues, LNAs (Locked Nucleoside Analogues), are able to provide valuable improvements to oligonucleotides with respect to affinity and specificity towards complementary RNA and DNA oligomers. The novel type of LNA modified oligonucleotides, as well as the LNAs as such, are useful in a wide range of diagnostic applications as well as therapeutic applications. Among these can be mentioned antisense applications, PCR applications, strand displacement oligomers, as substrates for nucleic acid polymerases, as nucleotide based drugs, etc. The present invention also relates to such applications.

  本发明涉及新型的双环和三环核苷酸和核苷酸类似物，以及包含这些元素的寡核苷酸。这些核苷酸类似物，即锁定核苷酸类似物（LNAs），能够为寡核苷酸提供与互补RNA和DNA寡聚物的亲和力和特异性方面的有价值的改进。这种新型的LNA修饰的寡核苷酸以及LNA本身在广泛的诊断应用和治疗应用中非常有用。其中包括反义应用、PCR应用、链置换寡聚物、作为核酸聚合酶的底物、作为基于核苷酸的药物等。本发明还涉及这些应用。
