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.

xanthene-forming condensation reaction yields rhodol and rhodamine dyes carrying a zinc-binding ligand that includes the aniline-type nitrogen donor of the fluorophores. Upon zinc coordination in neutralaqueoussolution, rhodol RF3 behaves as a ratiometric sensor, and rhodamine RA1 acts as a turn-off intensity-based indicator. Both fluorescent compounds bind the divalent zinc cation with micromolar

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.

2-pyridylmethyl)aminomethyl)-N-methylaniline]-6-hydroxy-3-xanthanone) is prepared via a convergent synthetic strategy developed from previous studies with these compounds. ZP4, like its predecessors, has excitation and emission wavelengths in the visible range ( approximately 500 nm), a dissociation constant (K(d)) for Zn(2+) of less than 1 nM and a high quantum yields (Phi = approximately 0.4), making
