Abstract
Superoxide anion (O2·-) and peroxynitrite (ONOO-), two important oxidants under oxidative stress, coexist in complex cell and organism systems, playing crucial roles in various physiological and pathological processes, particularly in neurodegenerative diseases. Despite the absence of robust molecular tools capable of simultaneously visualizing O2·- and ONOO- in biosystems, the relationship between these two species remains understudied. Herein, we present sequentially activated fluorescent probe, DHX-SP, which exhibits exceptional selectivity and sensitivity toward O2·- and ONOO-. This probe enables precise imaging of these species in living PC12 cells under oxidative stress conditions using distinct fluorescence signal combinations. Furthermore, the probe DHX-SP has the ability to visualize changes in O2·- and ONOO- levels during ferroptosis of PC12 cells and in the Parkinson's disease model. These findings establish a connection between the crosstalk of the phosphorus group of O2·- and ONOO- in PC12 cells under oxidative stress.

Abstract
BACKGROUND The cellular endoplasmic reticulum (ER) is responsible for various functions, including protein synthesis, folding, distribution, and calcium ion storage. Studies have linked ER stress with acute lung injury (ALI), which can result in oxidative stress and even cell death. Peroxynitrite (ONOO-) is a well-known reactive oxygen species (ROS) that contributes to various physiological and pathological processes in oxidative stress diseases. To understand the role of ER ONOO- in ALI, it is crucial to accurately measure its level in the ER. Unfortunately, there is currently no probe available to detect ER ONOO- in an ALI model. RESULTS To address this, we developed three near-infrared (NIR) fluorescent probes (DCM-F-ONOO, DCM-Cl-ONOO, and DCM-Br-ONOO) for the detection of ONOO- using pentafluorobenzenesulfonate (PFBS) moieties as fluorescence quenchers. Through comprehensive testing, we selected DCM-Br-ONOO as the best NIR fluorescent probe due to its rapid response (within 3 min), high selectivity, good sensitivity (LOD = 2.3 nM), and approximately 66-fold enhanced response to ONOO- in fluorescence intensity. The probe was successfully applied to detect changes in ONOO- levels induced by different drugs in the ER of living cells. Importantly, a significant increase in the level of ONOO- was observed in the ER of an ALI cell model (4.5-fold) and an ALI mouse model (2.5-fold) using the probe, which is essential for understanding the role of ONOO- in ER-associated diseases. SIGNIFICANCE Using DCM-Br-ONOO as a probe, present work further validated that the elevated levels of ONOO- secretion were accompanied by the ALI progressed. These findings may provide valuable results for figuring out the biological roles that ONOO- played in ALI.

Abstract
Two through-bond energy transfer fluorescent probes with a dihydroxyl naphthyl-pyrenyl conjugated system were synthesized for long-acting cyclic monitoring and eliminating peroxynitrite (ONOO- ). The probes exhibit large Stokes shifts (230 or 280 nm) and the fluorescence at 620 or 652 nm rapidly change in response to continuously variable concentrations of ONOO- under physiological conditions. The probes show good reversibility and can rapidly monitor the concentration changes of ONOO- in real time. In addition, with the additions of the probes, the decomposition of ONOO- is greatly accelerated. Therefore, the probes can effectively eliminate the excess ONOO- as well as sensing it. The biological studies showed that the probes can effectively and reversibly eliminate both exogenous and endogenous ONOO- in-situ as well as sensing its changes in cells, which can help to maintain the normal physiological concentration of ONOO- in organisms. This is the first system that a probe achieves multifunction including real-time detection, long-acting cyclic monitoring and in-situ elimination, thereby maintaining a normal physiological balance for ONOO- .

Abstract
Irregularities in mitochondrial viscosity and peroxynitrite (ONOO-) concentration can lead to mitochondrial dysfunction. It is still a great challenge to develop near-infrared (NIR) fluorescent probes to simultaneously detect viscosity, endogenous ONOO-, and mitophagy. Herein, a multifunctional mitochondria-targeting NIR fluorescent probe P-1 was first synthesized for simultaneously detecting viscosity, ONOO-, and mitophagy. P-1 used quinoline cations as a mitochondrial targeting moiety, arylboronate as an ONOO- responsive group, and detected the change of viscosity by the twisted internal charge transfer (TICT) mechanism. The probe has an excellent response to the viscosity during inflammation by lipopolysaccharides (LPSs) and mitophagy induced by starvation at 670 nm. The viscosity changes of the probe induced by nystatin in zebrafish showed that P-1 was able to detect microviscosity in vivo. P-1 also showed good sensitivity with a detection limit of 6.2 nM for ONOO- detection and was successfully applied to the endogenous ONOO- detection in zebrafish. Moreover, P-1 has the ability to distinguish between cancer cells and normal cells. All of these features make P-1 a promising candidate to detect mitophagy and ONOO- -associated physiological and pathological processes.
