  A Palette of Fluorescent Probes with Varying Emission Colors for Imaging Hydrogen Peroxide Signaling in Living Cells

  摘要：

  We present a new family of fluorescent probes with varying emission colors for selectively imaging hydrogen peroxide (H2O2) generated at physiological cell signaling levels. This structurally homologous series of fluorescein- and rhodol-based reporters relies on a chemospecific boronate-to-phenol switch to respond to H2O2 over a panel of biologically relevant reactive oxygen species (ROS) with tunable excitation and emission maxima and sensitivity to endogenously produced H2O2 signals, as shown by studies in RAW264.7 macrophages during the phagocytic respiratory burst and A431 cells in response to EGF stimulation. We further demonstrate the utility of these reagents in multicolor imaging experiments by using one of the new H2O2-specific probes, Peroxy Orange 1 (PO1), in conjunction with the green-fluorescent highly reactive oxygen species (hROS) probe, APF. This dual-probe approach allows for selective discrimination between changes in H2O2 and hypochlorous acid (HOCl) levels in live RAW264.7 macrophages. Moreover, when macrophages labeled with both PO1 and APF were stimulated to induce an immune response, we discovered three distinct types of phagosomes: those that generated mainly hROS, those that produced mainly H2O2, and those that possessed both types of ROS. The ability to monitor multiple ROS fluxes simultaneously using a palette of different colored fluorescent probes opens new opporunities to disentangle the complex contributions of oxidation biology to living systems by molecular imaging.

  The compositions of the present disclosure provide novel fluorogenic probes for use in the specific imaging and detection of mycobacteria species, and in particular β-lactam- antibiotic resistant. Specificity for mycobacteria is conferred on these probes by incorporating a moiety that specifically targets the unique trapping mechanism of the DprE1 found in in mycobacteria. Accordingly, only Mycobacteria species that express both a β- lactamase and DprE1 enable both the activation of the caged fluorescent probe, and the affixing of the released fluorescent probes to the bacteria cells through the functioning reduction-covalent binding mechanism. Advantageously, such a probe is able, at its most sensitive, to allow single mycobacterium detection.

  本公开的组成提供了新颖的生色团探针，用于特定地成像和检测分枝杆菌种类，尤其是对β-内酰胺类抗生素具有抗药性的种类。这些探针通过引入一种特定针对分枝杆菌中DprE1独特捕获机制的基团，从而实现对分枝杆菌的特异性。因此，只有表达β-内酰胺酶和DprE1的分枝杆菌种类才能激活笼状荧光探针，并通过功能性还原-共价结合机制将释放的荧光探针固定到细菌细胞上。这种探针的一个显著优点是，在其最敏感的情况下，能够实现单个分枝杆菌的检测。
