  The Components of xRNA: Synthesis and Fluorescence of a Full Genetic Set of Size-Expanded Ribonucleosides

  摘要：

  The synthesis and properties of a full set of four benzo-expanded ribonucleosides (xRNA), analogous to A, G, C, and U RNA monomers, are described. The nucleosides are efficient fluorophores with emission maxima of 369-411 nm. The compounds are expected to be useful as RNA pathway probes and as components of an unnatural ribopolymer.

  the RAS family are important regulators of cellular signaling and, when mutated, can drive cancer pathogenesis. Despite considerable effort over the last 30 years, RAS proteins have proven to be recalcitrant therapeutic targets. One approach for modulating RAS signaling is to target proteins that interact with RAS, such as the guanine nucleotide exchange factor (GEF) son of sevenless homologue 1 (SOS1)

  RAS家族中的蛋白质是细胞信号传导的重要调节剂，并且当突变时，可以驱动癌症的发病机理。尽管在过去30年中付出了巨大的努力，但RAS蛋白已被证明是顽固的治疗靶标。调节RAS信号的一种方法是靶向与RAS相互作用的蛋白，例如七无同源性1（SOS1）的鸟嘌呤核苷酸交换因子（GEF）。在这里，我们报告了对结合SOS1并激活RAS上的核苷酸交换的含喹唑啉类化合物的领先研究。使用基于结构的设计，我们优化了与喹唑啉核连接的取代基，并建立了在最初的HTS命中中不存在的其他相互作用。优化的化合物在体外以一位数的微摩尔浓度激活核苷酸交换。在HeLa细胞中，
