Abstract
In this work, a triphenylamine-benzofuran-derived fluorescent probe TBSF was developed for monitoring the sulfite level in Chinese medicinal materials and imaging in living cells. In the testing system, under 445 nm excitation, TBSF responded to sulfite steadily with a 540 nm fluorescence reporting signal. The testing system showed advantages including high sensitivity, rapid response, and high selectivity. In particular, TBSF achieved the sulfite detection in the water decoction of Chinese medicinal materials from both addition and excessive fumigation. It also realized the intracellular imaging of both exogenous and endogenous sulfite in living HepG2 cells. The imaging in water decoction-treated cells inferred the potential for the interdisciplinary detection.

Tian Q, Lu X, He W. Structure-regulated mitochondrial-targeted fluorescent probe for sensing and imaging SO 2in vivo. Bioorg Chem 2023; 138:106656. [PMID: 37329811 DOI: 10.1016/j.bioorg.2023.106656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 05/24/2023] [Accepted: 06/04/2023] [Indexed: 06/19/2023]
Abstract
SO2 and its derivatives play an important role in the antioxidation and anticorrosion of food and medicine. In biological systems, abnormal levels of SO2 lead to the occurrence of many biological diseases. Hence, the development of suitable tools for monitoring SO2 in mitochondria is beneficial for studying the biological effect of SO2 in subcellular organelles. In this research, DHX-1 and DHX-2 are fluorescent probes designed on the basis of dihydroxanthene skeletons. Importantly, DHX-1 (650 nm) and DHX-2 (748 nm) show near-infrared fluorescence response toward endogenous and exogenous SO2, which showed advantages of great selectivity, good sensitivity and low cytotoxicity, and the detection limit is 5.6 μM and 4.08 μM of SO2, respectively. Moreover, DHX-1 and DHX-2 realized SO2 sensing in HeLa cells and zebrafish. Moreover, cell imaging demonstrated that DHX-2 with a thiazole salt structure possesses good mitochondria-targeting ability. Additionally, DHX-2 was perfectly achieved by in situ imaging of SO2 in mice.

Abstract
In this work, the phenothiazine fragment with powerful electron-donating ability was specifically selected to construct a multifunctional detector (noted as T1) in double-organelle with near-infrared region I (NIR-I) absorption. The changes of SO2/H2O2 content in mitochondria and lipid droplets were observed through red/green channels respectively, which was due to the reaction between benzopyrylium fragment of T1 and SO2/H2O2 to achieve red/green fluorescence conversion. Additionally, T1 was endowed with photoacoustic properties deriving from NIR-I absorption to reversibly monitor SO2/H2O2in vivo. This work was significant for more accurately deciphering the physiological and pathological processes in living organisms.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignancies in the liver with poor prognosis. In order to improve the prognosis and overall survival of patients with HCC, it is important to identify it at early stage and resect it precisely. Cell microenvironment, active compounds, and enzymes may change during the cancerization of hepatocytes. Hypochlorous acid (HClO), one of the most significant signal molecules in the cellular signaling pathway, plays an important role in many cellular processes. To detect and treat liver cancers, it is imperative to study how HClO levels change in hepatocytes. However, developing fluorescent probes specific to liver cells to detect HClO still challenging. Herein, we designed and synthesized a NIR hepatocyte-specific fluorescent probe (MBH-MT) that displayed excellent optical properties for detecting HClO in biological samples. Cell imaging experiment conducted with the unique probe MBH-MT, showed that the biocompatible sensor is capable of monitoring HClO and distinguishing normal cells from cancer cells (e.g., HepG2, HUVEC, RAW264.7, L02 and HK-2 cells). An organ imaging experiment with the probe MBH-MT demonstrated its effectiveness in diagnosing and imaging hepatocellular carcinoma in vivo. MBH-MT's in situ imaging also demonstrated that it can target and image mouse hepatocellular carcinomas. Furthermore, MBH-MT has also successfully been used to diagnose and guide liver cancer surgery early. In the future, we expect that this powerful tool may be help in the detection and imaging of hepatocellular carcinoma, which may affect a large number of people.

Abstract
The biological microenvironment includes important parameters such as viscosity, polarity, temperature, oxygen content and pH. In particular, abnormal cell viscosity is associated with the development of major diseases. Sulphur dioxide (SO2) serves not only as an essential atmospheric pollutant but also an influential signalling molecule in biological cells, predisposing individuals to increased respiratory disease. In this work, we designed and synthesized a novel fluorescent probe CouCN-V&S with dual response to micro environmental viscosity and SO2. The probe monitored viscosity and SO2 separately through dual emission channels with a difference of 135 nm. The probe responded sensitively to SO2 (<1s) and exhibited satisfactory immunity to interference and pH stability. The probe was successfully applied to imaging cellular, intra-zebrafish viscosity and SO2 changes. Interestingly, we took onion epidermal cells as model and explored the capability of probe CouCN-V&S to image SO2 in plant cells for the first time.

Abstract
The development of effective methods for tracking cancer cells is of significant importance in the early diagnosis and treatment of tumor diseases. Compared with the developed techniques, the electrochemical assay has shown considerable potential for monitoring glycan expression on the cell surface using nondestructive means. However, the application expansion of the electrochemical strategy is strongly impeded owing to its dependence on electroactive species. In this study, a competitive electrochemical strategy was reported for monitoring cancer cells based on mannose (a typical glycan) as a clinical biomarker. Herein, functionalized carbon nanotubes were used to load the thiomannosyl dimer, and thionine-interlinking signal probes were designed for competitive recognition. After effective competition between cancer cells and the anchored mannose, a decreased current was obtained as the cell concentration increased. Under optimal conditions, the proposed biosensor exhibited attractive performance for cancer cell analysis with a detection limit as low as 20 cells per mL for QGY-7701 and 35 cells per mL for QGY-7703, facilitating great promise for the sensitive detection of cancer cells and thus showing potential applications in cancer diagnosis.
