  • A “turn-on” fluorescent and colorimetric chemodosimeter for selective detection of Au<sup>3+</sup>ions in solution and in live cells<i>via</i>Au<sup>3+</sup>-induced hydrolysis of a rhodamine-derived Schiff base

    A chromogenic and “off–on” fluorogenic chemodosimeter (L) based on a naphthalene–rhodamine B derivative was designed, synthesized and characterized for the selective and sensitive detection of Au3+ ions in mixed acetonitrile aqueous medium in the presence of other competitive analytes. Probe L displayed a 696-fold “turn-on” fluorescence signal enhancement toward Au3+ ions with the detection limit of

  • 一种荧光标记探针及其制备方法及对蛋白的 标记应用
    申请人:南开大学
    公开号:CN105859705B
    公开(公告)日:2019-02-26
    本发明公开了一种荧光探针及其制备方法及对蛋白质的标记应用。采用有机合成的方法,直接在罗丹明B骨架结构的底环上引入具有荧光性质的、多个杂原子的噁二唑杂环。引入的噁二唑杂环,既作为第二荧光团拓展罗丹明类荧光探针的光谱性质,又通过引入多个杂原子增加形成氢键的位点,利于与蛋白质中的氨基酸作用。在化合物RH‑MCl中,噁二唑环一侧由罗丹明B取代,另一侧由甲基取代。本发明还提供了应用该荧光探针进行蛋白质凝胶电泳荧光标记的方法。化合物RH‑MCl具有良好的溶性,其对蛋白质的荧光标记方法简单,用时少,敏感性高,重现性好、标记背景好、兼容性好、使用安全、成本低等优点。
  • Organometallic Activation of a Fluorogen for Templated Nucleic Acid Detection
    作者:Raphael M. Franzini、Eric T. Kool
    DOI:10.1021/ol800878b
    日期:2008.7.17
    A nucleic acid detection scheme that employs DNA-mediated delivery of an organomercury activator to unmask a fluorophore is described. The approach relies on adjacent hybridization of two oligonucleotide conjugates containing organomercury and caged rhodamine functionalities. Postsynthetic conjugation of amino-modified DNAs enabled efficient preparation of these probes. Complementary DNA templates yielded fluorescence signals arising from metal-assisted rhodamine uncaging.
  • A Turn-on Fluorescent Iron Complex and Its Cellular Uptake

    In the treatment of chronic iron overload disorders, ligands capable of complexing so-called "labile" (nonprotein bound) Fe are required to enter iron-loaded cells, sequester excess Fe, and then exit the cell (and the body) as an intact Fe complex. Despite the emergence of several ligand families that show high activity in mobilizing intracellular Fe, the mechanism and the locations of these subcellular labile Fe pools are still poorly understood. Our previous studies have unearthed a class of heterocyclic hydrazine-based chelators (e.g., benzoyl picolinoyl hydrazine, H2BPH) that show excellent activity at mobilizing Fe from Fe-loaded cells. Herein, we have grafted a fluorescent tag (rhodamine B) onto H2BPH to generate a ligand (L-1) that is nonfluorescent in its uncomplexed form but becomes strongly fluorescent in complex with Fe-III. The free ligand and its 1:2 Fe complex [Fe-III(L-1)(2)](3+) have both been fully characterized spectroscopically and with X-ray crystallography. Confocal fluorescent microscopy of HeLa cells incubated with [Fe-III(L-1)(2))(3+) shows that the complex rapidly enters HeLa cells and localizes within endosomes/lysosomes.
