    摘要:
    荧光点亮 RNA 适配体 (FLAP) 已成为可视化活细胞中 RNA 的有前途的工具。FLAPs 与其非荧光同源配体的特异性结合导致荧光显着增加,从而允许 RNA 成像。在这里,我们提出了一种变色适体-荧光团系统,其中游离染料为青色荧光,而适体-染料复合物为近红外 (NIR) 荧光。与其他报道的 FLAPs 不同,该系统能够实现比率 RNA 成像。为了设计变色系统,我们合成了一系列环境敏感的苯并吡喃-香豆素杂化荧光团,它们在青色荧光螺环形式和 NIR 荧光两性离子形式之间处于平衡状态。作为 RNA 标签,我们进化出 38 个核苷酸的适体,以纳摩尔亲和力选择性结合两性离子形式。

    The present invention relate to a novel silane coupling agent and a medical and/or dental curable composition comprising the same. It is an object of the present invention to provide a novel silane coupling agent that imparts high affinity to a radical polymerizable monomer, thereby imparting high mechanical strength, flexibility and durability when used for a medical and/or dental curable composition, and an inorganic filler surface-treated with the novel silane coupling agent and a novel medical and/or dental curable composition. A silane coupling agent including repeating units such as a urethane bond and polyethylene glycol (ether bond) at a specific position is used.

    Abstract Four novel coumarin derivatives were synthesized and characterized via MS, 1 H NMR, FT-IR, and UV–vis absorption spectra. The fluorescence behaviors of the compounds in DFM solutions were observed. The compounds exhibited strong blue and green emissions under ultraviolet light excitation.
