Abstract
We report a mitochondria-targeted nitroreductase (NTR)-activated near-infrared fluorescent probe: CS-NO2. Overexpressed NTR in mitochondria was measured with high sensitivity. More importantly, the probe CS-NO2 successfully monitored NTR activity in solid tumors and a hind-limb model of ischemia in mice. This novel finding indicates the promising function of our probe for the diagnosis of solid tumors and hypoxia-associated diseases.

Abstract
The detection of intracellular nitroreductase (NTR) activity is important for the study of hypoxia in organisms. In the present study, a Rhodol-derived fluorescent chemosensor (Rhod-NO2) was synthesized in a one-step procedure. Rhod-NO2 exhibits 110-fold fluorescence enhancement in the presence of NTR. Moreover, Rhod-NO2 demonstrates high NTR selectivity and sensitivity (LOD, 0.6 ng/mL). The mode of Rhod-NO2 binding to NTR was also revealed by molecular docking. In addition, the reaction and luminescence mechanisms were evaluated by MS and TDDFT theoretical calculations, respectively. Finally, Rhod-NO2 was successfully applied to monitor NTR production during Escherichia coli (E. coli) growth, and to visually analyze NTR production in malignant oral cancer cells under hypoxia. Thus, Rhod-NO2 represents a new molecular tool to further understanding of the biological function of NTR.

Abstract
Aromatic nitro compounds are reduced to their corresponding amino derivatives by nitroreductases (NTR), while identification and characterization of the corresponding enzymes in mammalian systems are yet unrevealed. However, mammalian NTR activity has been considered as a favorable target in development of theranostic agents for cancer and hypoxia of solid tumors. Currently, small molecule-based fluorescent probes have emerged as a valuable assay tool for NTR activity. However, there has been a limit to comparing NTR activity between different cells, since most probes have relied on fluorescence changes that are affected by not only enzymatic activity but also nonenzymatic factors. Here, we developed a self-calibrating bipartite fluorescent probe, consisting of NTR-sensitive nitronaphthalimide and nonsensitive coumarin moieties. Thereby, it was possible to compare the relative NTR activity by monitoring fluorescence ratios in noncancerous and some cancerous cells and to demonstrate for certain that the elevated NTR activity is associated with cancer cells and hypoxia states.

Abstract
Nitroreductase (NTR) may be more active under the environment of hypoxic conditions, which are the distinctive features of the multiphase solid tumor. It is of great significance to effectively detect and monitor NTR in the living cells for the diagnosis of hypoxia in a tumor. Here, we synthesized a novel turn-on fluorescent probe NTR-NO2 based on a fused four-ring quinoxaline skeleton for NTR detection. The highly efficient probe can be easily synthesized. The probe NTR-NO2 showed satisfactory sensitivity and selectivity to NTR. Upon incubation with NTR, NTR-NO2 could successively undergo a nitro reduction reaction and then generate NTR-NH2 along with significant fluorescence enhancement (30 folds). Moreover, the fluorescent dye NTR-NH2 exhibits a large Stokes shift (Δλ = 111 nm) due to the intramolecular charge transfer (ICT) process. As a result, NTR-NO2 displayed a wide linear range (0–4.5 μg mL−1) and low detection limit (LOD = 58 ng mL−1) after responding to NTR. In addition, this probe was adopted for the detection of endogenous NTR within hypoxic HeLa cells. Probe NTR-NO2 was effectively reduced in the presence of NTR generating a highly fluorescent product.![]()

Abstract
Nitroreductase (NTR) belongs to a class of flavin mononucleotide-dependent and flavin adenine dinucleotide-dependent cytoplasmic enzymes; its contents in tumor cells increase during hypoxia. The development of fluorescent probes for detection of NTR activity is of great significance for the study of the state of hypoxia in living organisms. In this paper, a red-emitting fluorescence turn-on probe EBI-NO2 was synthesized using a one-step method. The fluorescence of the probe was enhanced by 60 folds in the presence of NTR. The probe also had high selectivity towards NTR, and its detection limit was as low as 1 ng/mL. The reaction mechanism was verified using MS, molecular docking and theoretical calculations. In addition, it was successfully applied in real-time monitoring of NTR produced during growth of Escherichia coli (BL21) and in visualization of NTR in oral cancer cells (Cal-27) under hypoxia. This work provides a new imaging tool that can be applied to investigate the physiological and pathological changes in hypoxia oral cells.
