for a means by which to constrain RNA structure, either to reduce its conformational flexibility or to help distinguish between alternative structural models. To address this need, we have developed chemistry that permits the site-specific introduction of functionalizable tethers into RNA. Here we report the design and synthesis of reagents for use in solid-phase RNA synthesis that allow the functionalization
RNA结构的知识可以极大地促进对其生物学功能的理解。然而,RNA 的物理特性,尤其是其构象异质性,阻碍了高分辨率结构分析。因此,较低分辨率的方法,如生化探测、系统发育分析和分子建模,已在 RNA 科学中发挥重要作用。这种情况导致需要一种方法来约束 RNA 结构,以减少其构象灵活性或帮助区分替代结构模型。为了满足这一需求,我们开发了化学方法,允许将可功能化的系链特定于位点引入 RNA。在这里,我们报告了用于固相 RNA 合成的试剂的设计和合成,这些试剂允许 G、C 和 A 残基的碱基部分的功能化。在掺入寡核苷酸中并随后用烷基胺处理后,可转化的核苷衍生物...
