Provided herein are improved fluorogenic compounds and probes that can be used as reagents for measuring, detecting and/or screening hypochlorous acid or hydroxyl radical. The fluorogenic compounds of the invention can produce fluorescence colors, such as green, yellow, red, or far-red. Also provided herein are fluorogenic compounds for selectively staining hypochlorous acid or hydroxyl radical in the mitochondria of living cells. Provided also herein are methods that can be used to measure, directly or indirectly, the presence and/or amount of hypochlorous acid or hydroxyl radical in chemical samples and biological samples such as cells and tissues in living organisms. Also provided are high-throughput screening methods for detecting or screening hypochlorous acid or hydroxyl radical or compounds that can increase or decrease the level of hypochlorous acid or hydroxyl radical in chemical and biological samples.
本发明提供了可用作测量、检测和/或筛选次氯酸或羟基自由基试剂的改进型致氟化合物和探针。本发明的致氟化合物可产生荧光颜色,如绿色、黄色、红色或远红色。本文还提供了用于选择性染色活细胞线粒体中次氯酸或羟自由基的含氟化合物。本文还提供了可用于直接或间接测量化学样品和生物样品(如活生物体的细胞和组织)中次氯酸或羟自由基的存在和/或数量的方法。本文还提供了高通量筛选方法,用于检测或筛选化学和生物样品中的次氯酸或羟自由基或可增加或减少次氯酸或羟自由基水平的化合物。
