Abstract
Hypochlorite (ClO- ), as a kind of essential reactive oxygen species, plays a crucial role in vitro and in vivo. Here, a ratiometric fluorescent probe (TPAM) was designed and constructed for sensing ClO- based on substituted triphenylamine and malononitrile, which exhibited obvious colour transfer from orange to colourless under daylight accompanied by noticeable fluorescence change from red to green in response to ClO- . TPAM could effectively monitor ClO- with the merits of fast response, excellent selectivity, high sensitivity and a low detection limit of 0.1014 μM. 1 H NMR, mass spectra and theoretical calculations proved that ClO- caused the oxidation of the carbon-carbon double bond in TPAM, resulting in compound 1 and marked changes in colour and fluorescence. In addition, TPAM was utilized for imaging ClO- in living cells successfully with good photostability and biocompatibility.

Organelle-Targeted Fluorescent Probes for Sulfane Sulfur Species. Antioxidants (Basel) 2023; 12:antiox12030590. [PMID: 36978838 PMCID: PMC10045342 DOI: 10.3390/antiox12030590] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 02/19/2023] [Accepted: 02/22/2023] [Indexed: 03/02/2023] Open
Abstract
Sulfane sulfurs, which include hydropersulfides (RSSH), hydrogen polysulfides (H2Sn, n > 1), and polysulfides (RSnR, n > 2), play important roles in cellular redox biology and are closely linked to hydrogen sulfide (H2S) signaling. While most studies on sulfane sulfur detection have focused on sulfane sulfurs in the whole cell, increasing the recognition of the effects of reactive sulfur species on the functions of various subcellular organelles has emerged. This has driven a need for organelle-targeted detection methods. However, the detection of sulfane sulfurs, particularly of RSSH and H2Sn, in biological systems is still a challenge due to their low endogenous concentrations and instabilities. In this review, we summarize the development and design of organelle-targeted fluorescent sulfane sulfur probes, examine their organelle-targeting strategies and choices of fluorophores (e.g., ratiometric, near-infrared, etc.), and discuss their mechanisms and ability to detect endogenous and exogenous sulfane sulfur species. We also present the advantages and limitations of the probes and propose directions for future work on this topic.

Abstract
In this research, we constructed a styrylpyridine derivative-based fluorescent probe MITO-PQDNs to monitor mitochondrial glutathione (GSH). The probe MITO-PQDNs could react rapidly (20 min) with GSH in PBS buffer and exhibited a strong fluorescence signal (586 nm) as well as a significant Stokes shift (200 nm). Moreover, MITO-PQDNs could quantitatively detect GSH with high sensitivity (LOD = 253 nM). Meanwhile, MITO-PQDNs possessed favorable biocompatibility and could detect both endogenous and exogenous GSH in MCF-7 cells. Above all, MITO-PQDNs enabled the detection of fluctuations in mitochondrial GSH concentrations during oxidative stress.

Abstract
Hypochlorous acid (HClO) as a biomarker of inflammation has been implicated in redox signaling and combating microbial infection. Therefore, it is of great significance to develop an efficient method for detection and analysis of HClO in osteoarthritis. Herein, a new"turn-off" mitochondria-targetable NIR fluorescent probe, NIR-ClO, was reported for specific analysis and imaging of osteoarthritis response-related HOCl levels in vitro and in vivo. In the presence of HClO, due to the specific HOCl-triggered C = C bond cleavage reaction, NIR-ClO obtained a high sensitive and selective fluorescence "On-Off" response toward HClO with a good limit of detection(LOD) as low as 28.3 nM, and showed a fast response time (<60 s) , which allow it to be used for detection of HClO under a simulated physiological condition. In addition, NIR-ClO was successfully used to imaging of HClO in living RAW264.7 cells and osteoarthritis model rat. The results suggest that NIR-ClO is a robust tool for future studies on diagnosis osteoarthritis.

SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2022; 268:120708. [PMID: 34915231 DOI: 10.1016/j.saa.2021.120708] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 11/30/2021] [Accepted: 12/01/2021] [Indexed: 06/14/2023]
Abstract
Hydrogen polysulfides (H2Sn, n > 1) belongs to sulfane sulfur in the reactive sulfur species (RSS) family and plays a significant regulatory role in organisms. Highly selective and lysosome-located probes for detecting hydrogen polysulfides are rare. Thus, it is important to develop a technique to detect the changes of H2Sn level in lysosomes. In this work, a lysosome-targeting fluorescent probe for H2Sn was designed and developed based on a naphthalimide derivative. 4-Hydroxynaphthalimide was selected as the fluorescent group and 2-chloro-5-nitrobenzoate group was used as a specific recognition unit for H2Sn. A morpholine unit was chosen as a lysosome-located group. In the absence of H2Sn, the fluorescent probe exhibited almost no fluorescence. In the presence of H2Sn, the fluorescent probe showed strong fluorescence owing to H2Sn-mediated aromatic substitution-cyclization reactions. The fluorescence emission intensity at 548 nm of the probe showed a good linear relationship toward H2Sn in the range of 2.0 × 10-7 - 9.0 × 10-5 mol·L-1, and the detection limit was found to be 1.5 × 10-7 mol·L-1. The probe possessed a wide work range of pH, including the pH of physiological environment, and high selectivity for H2Sn. There are almost no cytotoxicity and the ability of detecting endogenous and exogenous H2Sn in lysosomes. These results indicate that the fluorescent probe can provide a good tool for intracellular and extracellular detection of H2Sn.

A novel fluorescent probe with large Stokes shift for accurate detection of HOCl in mitochondria and its imaging application. Anal Chim Acta 2022; 1191:339287.

Abstract
Hypochlorous acid (HOCl), mainly generated in mitochondria, plays a critical role in various physiological processes. To better understand the role and function of HOCl in mitochondria, herein, we present the design and synthesis of a Mito-QL reporter for probing the HOCl within mitochondria without other interference generated in living cells. Through the combination of TICT/ICT mechanisms, probe Mito-QL, with large stokes shift (203 nm) and low background fluorescence, exhibited excellent sensitivity (900-fold fluorescence enhancement) and selectivity towards HOCl (LOD = 2.4 nM). The co-location experiments confirmed that probe Mito-QL can firstly localize in the mitochondria and then react with HOCl in mitochondria. Also, the probe is capable of imaging endogenous and exogenous HOCl even the generation of HOCl during the ferroptosis of cells, which is beneficial for more efficient application in biological imaging.
