Spirocyclization of xanthene dyes has become a powerful technique for developing fluorescent probes. Herein, we extend this unique fluorescence switching mechanism to near-infrared (NIR) dye, 2-(7-diethylamino-2-oxo-2H-1-benzopyran-3-yl)-4-(2-carboxyphenyl)-7-diethylamino-1-benzopyrylium (CB), and construct ratiometric probe 1 cysteine (Cys)/homocysteine (Hcy). The sensing toward Cys/Hcy is realized by utilizing tandem native chemical ligation/spirocyclization reaction interrupt the large...

Hypochlorous acid (HOCl), a reactive oxygen species (ROS), plays crucial role in the process of pathogenic oxidative stress. Some powerful anticancer agents, such as elesclomol, specifically induce cancer cell apoptosis by increasing HOCl levels. However, sensitive tools to monitor subtle changes biological vivo are limited. To achieve this, we herein present rationally designed probes C1-C7 through introducing bioorthogonal dimethylthiocarbamate receptor. All were shown sensitively and...

Abstract The tracking of cellular senescence usually depends on the detection senescence‐associated β‐galactosidase (SA‐β‐gal). Previous probes for SA‐β‐gal with this purpose only cover a single dimension: accumulation enzyme in lysosomes. However, is insufficient to determine destiny because endogenous β‐gal enriched lysosomes not related senescence, but also some other physiological processes. To address issue, we introduce our fluorescent including second lysosomal pH, since...

A novel coumarin-based fluorogenic probe bearing the tris unit (DAT-1) with high selectivity and suitable affinity toward Fe3+ over other cations tested was developed in biological systems. The sensing mechanism studied by quantum calculations. can be applied to monitoring of aqueous solution a pH span 3–8. In addition, imaging, membrane permeability nontoxicity demonstrate that DAT-1 could act as turn-off fluorescent chemosensor for living cells.

Hypochlorous (HOCl) acid is generated as a defense tool in the immune system and plays vital role killing wide range of pathogens. There therefore great interest developing fluorescent probes that can endogenously respond to change concentration HOCl vivo. To address this challenge, we here present rapidly responding probe RO610 image endogenous living mice. The development was based on novel water-soluble pH-independent xanthene dye, 2'-formylrhodol ROA, which exhibits highly selective...

Abstract A hybrid coumarin–thiazole compound was developed as a novel ratiometric and colorimetric sensor for bisulfite anions. Structure identification of the confirmed by 1 H NMR, 13 C H, COSY, heteronuclear single quantum coherence (HSQC), IR, HRMS spectroscopy. The detection anions performed through Michael addition anion toward sensor. reaction between caused fluorescence intensity to decrease at 600 nm increase 450 simultaneously yielded visible color change from purplish red colorless...

Delayed wound healing is one of the major diabetes complications that occur in 25% diabetic patients. Specific management and combination treatment are required to repair wound, which still remains a challenge with few effective therapies available currently. In this work, new H2S donor PRO-F, characterized by capability promote diabetes, was designed. PRO-F can be activated light without consuming endogenous substances accompanying fluorescent signal makes real-time tracking released...

Diagnosing aging for preventative intervention generally relies on the tracking of biomarkers in resting state. However, static marker levels are insufficient to fully evaluate aging, particularly given that stress response capacity (SRC) decay is currently viewed as a critical feature aging. Therefore, we have developed dual-channel fluorescent probe ROKS capable logic-based visualization thiophenol (stressor) and HOCl (thiophenol-activated product) vivo, which provides new strategy from...
