  摘要：

  化学修饰碱基常用于稳定核酸、研究核酸结构形成的驱动力以及调整 DNA 和 RNA 杂交条件。核苷类似物是研究氢键、碱基堆积和溶解这三种导致核酸稳定性的主要作用力的化学手段。为了更深入地了解这些相互作用对 RNA 稳定性的贡献，我们决定合成一些新型核酸类似物，用氟化吲哚取代核碱基。氟化吲哚可与氟化苯并咪唑进行比较，以确定氮在五元环系统中的作用。本文报告了氟吲哚核糖核苷的合成以及所有合成的氟吲哚核糖核苷的 X 射线晶体结构。这些化合物也可能成为多种具有生物活性的 RNA 类似物的构建基块。

  Indolmycin (IND) is a microbial natural product that selectively inhibits bacterial tryptophanyl-tRNA synthetase (TrpRS). The tryptophan biosynthesis pathway was recently shown to be an important target for developing new antibacterial agents against Mycobacterium tuberculosis (Mtb). We investigated the antibacterial activity of IND against several mycobacterial model strains. A TrpRS biochemical assay
