Provided herein are compounds or fluorogenic probes which can be used as reagents for measuring, detecting and/or screening ROS or RNS such as peroxynitrite or hypochlorite. Provided also herein are methods that can be used to measure, directly or indirectly, the amount of peroxynitrite or hypochlorite in chemical samples and biological samples such as cells and tissues in living organisms. Specifically, the methods include the steps of contacting the fluorogenic probes disclosed herein with the samples to form one or more fluorescent compounds, and measuring fluorescence properties of the fluorescent compounds. Provided also herein are high-throughput screening fluorescent methods for detecting or screening peroxynitrite or compounds that can increase or decrease the level of peroxynitrite or hypochlorite in chemical and biological samples.
本发明提供了可用于测量、检测和/或筛选过氧亚硝酸盐或次氯酸盐等活性氧或活性氮化合物的化合物或荧光生成探针。本发明还提供了可用于直接或间接测量化学样品和生物样品(如活体生物的细胞和组织)中过氧亚硝酸盐或次氯酸盐含量的方法。具体而言,这些方法包括将本发明披露的荧光生成探针与样品接触以形成一种或多种荧光化合物,并测量荧光化合物的荧光特性。本发明还提供了用于检测或筛选过氧亚硝酸盐或能够增加或减少化学和生物样品中过氧亚硝酸盐或次氯酸盐水平的化合物的高通量筛选荧光方法。
