  oxetane ring. The E-type conformation is confirmed by molecular modeling and NMR. The nucleoside is incorporated into short α-DNA sequences. In a mixed pyrimidine context, these recognize complementary parallel RNA-sequences with mainly increased affinity and complementary parallel DNA-sequences with decreased affinity. The present bicyclic analogue represents the first conformationally restricted α-DNA-analogue

  合成了被2'-3'-稠合的氧杂环丁烷环严格限制在E-型构象中的α- d-阿拉伯糖基构型的双环核苷。朝向目标化合物的几种合成策略被描述，并且从成功制备d -木糖衍生物是基于双键的钌-介导的裂解，一个S Ñ 2反转在2-位，得到阿糖-构型，核碱基偶联，最后闭环得到氧杂环丁烷环。该Ë-型构象通过分子建模和NMR确认。核苷被掺入短的α-DNA序列中。在混合的嘧啶环境中，它们识别亲和力主要增加的互补平行RNA序列和亲和力降低的互补平行DNA序列。本双环类似物代表第一个构象受限的α-DNA类似物，以改善与α-DNA单体的混合器中的核酸识别。

  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.
