  Determination of intracellular pH using sensitive, clickable fluorescent probes

  摘要：

  We synthesized and evaluated a series of acidic fluorescent pH probes exhibiting robust pH dependence, high sensitivity and photostability, and excellent cell membrane permeability. Titration analyses indicated that probe 3 could increase its fluorescence intensity 800-fold between pH 8.0 and 4.1. Additionally, its pK(a) value is optimal for intracellular probing of acidic organelles. Fluorescent imaging of HepG2 and Hela cells further revealed that probe 3 demonstrates outstanding capacity for monitoring of intracellular [H+] levels. The easily accessible terminal alkyne/azido function groups of these probes offer the possibility of rapidly constructing sensor molecule libraries using 'click' chemistry.

  New Rhodamine Nitroxide Based Fluorescent Probes for Intracellular Hydroxyl Radical Identification in Living Cells

  摘要：

  The synthesis, characteristics, and biological applications of a series of new rhodamine nitroxide fluorescent probes that enable imaging of hydroxyl radicals (center dot OH) In living cells are described. These probes are highly selective for center dot OH in aqueous solution, avoiding interference from other reactive oxygen species (ROS), and they facilitate center dot OH imaging in biologically active samples. The robust nature of these probes (high specificity and selectivity, and facile synthesis) offer distinct advantages over previous methods for center dot OH detection.

  Described herein are compounds that may selectively stain lysosomes in cells, which may be used in methods of selectively staining and selectively detecting lysosomes in cells. The compounds are fluorescently labelled carbohydrates in which one or two monosaccharides selected from the group mannose, N- acetyl glucosamine, fucose, galactose and sialic acid are linked via a linker to a fluorescent probe such as rhodamine or cyanine or related probes.
