  often rely on sample destruction or extensive processing, resulting in a loss of spatiotemporal information. To help address these limitations, here we present the design, synthesis, and biological evaluation of a first-generation activity-based sensing system for live-cell formate imaging that relies on iridium-mediated transfer hydrogenation chemistry. Formate facilitates an aldehyde-to-alcohol conversion

  甲酸盐是一碳代谢中的主要活性碳种类，它是氨基酸和核酸生物合成的内源性前体，也是 NAD（P）H 的细胞来源。另一方面，细胞甲酸盐的异常升高与严重疾病的进展有关，包括癌症和阿尔茨海默病。生物环境中甲酸盐检测的传统方法通常依赖于样品销毁或大量处理，从而导致时空信息的丢失。为了帮助解决这些限制，我们在这里介绍了第一代基于活性的传感系统的设计、合成和生物学评估，该系统依赖于铱介导的转移氢化化学，用于活细胞甲酸盐成像。甲酸盐有助于在各种荧光基团支架上进行醛-醇的转化，以实现该单碳单元的荧光检测，包括通过内部校准的双色比率响应。所得的双组分探针系统可以检测活细胞中甲酸盐水平的变化，对潜在竞争性生物分析物具有高选择性。此外，这种基于活性的传感系统可以通过改变基于细胞的人结肠癌模型中的一碳通路来可视化内源性甲酸盐通量的变化，预示着这种化学方法在探索癌症和其他疾病中一碳代谢和信号之间的连续体的潜在效用。

  A radiation-sensitive composition containing a resist compound having a high sensitivity, a high resolution, a high etching resistance, and a low outgas which forms a resist pattern with a good shape is described. Further described is a method of forming a resist pattern using the radiation-sensitive composition. Still further described are a novel composition for forming a photoresist under coat film which is excellent in optical properties and etching resistance and contains substantially no sublimable substance and an under coat film formed by the composition. Still further described are a radiation-sensitive composition containing a solvent and a cyclic compound having a specific structure, for example, a cyclic compound (A) having a molecular weight of 700 to 5000 which is synthesized by the condensation reaction of a compound having 2 to 59 carbon atoms and 1 to 4 formyl groups (aldehyde compound (A1)) with a compound having 6 to 15 carbon atoms and 1 to 3 phenolic hydroxyl groups (phenol compound (A2)), and a cyclic compound for use in the radiation-sensitive composition.
