  2‘-Modified-2-thiothymidine Oligonucleotides

  摘要：

  graphicOligonucleotides with novel modifications, 2'-O[2-(methoxy)ethyl]-2-thiothymidine and 2'-deoxy-2'-fluoro-2-thiothymidine, have been synthesized. These modified oligonucleotides exhibited very high thermal stability when hybridized with complementary RNA. 2-O-(2-Methoxy)ethyl-2-thiothymidine modified oligonucleotide phosphodiesters showed enhanced resistance toward nucleases (t(1/2) > 24 h), but 2'-deoxy-2'-fluoro-2-thiothymidine modified oligonucleotide phosphodiesters showed limited stablity to nucleotytic degradation.

  The present invention relates to nucleoside compositions comprising novel nucleobases and oligomeric compounds comprising at least one such nucleoside. These oligomeric compounds typically have enhanced binding affinity properties compared to oligomeric compounds without the modification. The oligomeric compounds are useful, for example, for investigative and therapeutic purposes.

  本发明涉及包含新型核碱基的核苷酸组合物以及包含至少一种此类核苷酸的寡聚合物化合物。这些寡聚合物化合物通常具有比没有这种修饰的寡聚合物化合物更强的结合亲和性能。这些寡聚合物化合物可用于调查和治疗等用途。
