Provided herein are improved fluorogenic compounds and probes that can be used as reagents for measuring, detecting and/or screening peroxynitrite. 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 peroxynitrite 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 peroxynitrite 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 peroxynitrite or compounds that can increase or decrease the level of peroxynitrite in chemical and biological samples.
本发明提供了改进的致氟化合物和探针,可用作测量、检测和/或筛选过亚硝酸盐的试剂。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过亚硝酸的含氟化合物。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)中过亚硝酸的存在和/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过亚硝酸盐或可提高或降低过亚硝酸盐水平的化合物。
