A near-infrared turn-on fluorescent probe for ultrafast and highly specific detection of sulfite as well as its applications in food and bioimaging. Bioorg Chem 2025; 161:108541. [PMID: 40319813 DOI: 10.1016/j.bioorg.2025.108541] [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: 02/14/2025] [Revised: 04/12/2025] [Accepted: 04/25/2025] [Indexed: 05/07/2025]
Abstract
As one of the four important gas signaling molecules, sulfide dioxide (SO2) played critical roles within the normal physiological concentration, thus benefiting the health of human beings. While serious complications of multifarious diseases have been proven to be associated with abnormal levels of SO2 in tissues or organisms. Therefore, exploiting high-performance fluorescent probe is of great significance for the differentiation of SO2 in living organisms and processed foodstuffs. In this work, a near-infrared "turn-on" probe FMQ, which using 2-(1-(4-dimethylaminophenyl)ethylidene)malononitrile and N-methylquinoline trifluoromethanesulfonate as acceptors and furan as π linker, has been successfully designed and prepared for distinguishing sulfite (SO32-). Compared with our previous work, a near-infrared fluorescence emission at 760 nm of FMQ was attributed to its larger intramolecular D-π-A delocalization system in presence of SO32-. Simultaneously, probe FMQ showed ultrafast response (∼5 s), high selectivity, and superb sensitivity towards SO2 with low detection limit (44.98 nM) in a linear detection range of 0-15 μM. The recognition mechanism, which was triggered by the Michael nucleophilic addition of SO32- towards activated 4-position olefin carbon atom in quinolinium, was confirmed through the analysis of 1H NMR and HRMS spectra. Moreover, FMQ has been successfully employed for the detection of SO2 in food samples, living cells and zebrafish. Satisfactorily, this research demonstrated that FMQ exhibited significant potential for sniffing SO2 within both complex biological systems and food samples.

Abstract
Near-infrared organic small molecule luminescent materials have the advantages of easy modification, high quantum efficiency, good biological affinity, and color adjustability; thus, have promising application prospects in the fields of photoelectric devices, sensitive detection, photodynamic therapy, and biomedical imaging. However, traditional organic luminescent molecules have the problems of short emission wavelength, aggregation-causing emission quenching, and low quantum yield. Herein, we successfully synthesized four D-π-A-D light-emitting molecules based on electron-withdrawing malonitrile group and different electron-donating arylamine groups. These compounds showed satisfactory solvatochromism, aggregation-induced emission, red and near-infrared fluorescence, high photoluminescence quantum efficiency and temperature response properties. This successful example of molecular engineering provides a valuable reference for the development of advanced NIR materials with AIE and temperature-sensitive properties.

Abstract
Temperature homeostasis is critical for cells to perform their physiological functions. Among the diverse methods for temperature detection, fluorescent temperature probes stand out as a proven and effective tool, especially for monitoring temperature in cells and suborganelles, with a specific emphasis on mitochondria. The utilization of these probes provides a new opportunity to enhance our understanding of the mechanisms and interconnections underlying various physiological activities related to temperature homeostasis. However, the complexity and variability of cells and suborganelles necessitate fluorescent temperature probes with high resolution and sensitivity. To meet the demanding requirements for intracellular/subcellular temperature detection, several strategies have been developed, offering a range of options to address this challenge. This review examines four fundamental temperature-response strategies employed by small molecule and polymer probes, including intramolecular rotation, polarity sensitivity, Förster resonance energy transfer, and structural changes. The primary emphasis was placed on elucidating molecular design and biological applications specific to each type of probe. Furthermore, this review provides an insightful discussion on factors that may affect fluorescent thermometry, providing valuable perspectives for future development in the field. Finally, the review concludes by presenting cutting-edge response strategies and research insights for mitigating biases in temperature sensing.

Abstract
Acute liver failure caused by hepatic ischemia reperfusion injury (HIRI) poses a severe threat to life, emphasizing the urgent need for precise and timely early diagnosis. Viscosity, a key parameter reflecting active analyte levels at the cellular level, remains underexplored in relation to HIRI. To address this gap, we have developed a groundbreaking near-infrared molecule rotator, PN, exhibiting exceptional characteristics. PN demonstrates remarkable sensitivity, with a 32-fold change in response to viscosity, ranging from PBS to glycerol solution. PN's distinctive features include maximum emission wavelength 790 nm, as well as an impressive Stokes shift 190 nm. Moreover, PN exhibits the ability to sensitively and selectively differentiate nystatin-induced viscosity changes within living cells, and can be used for the detection of viscosity changes in the HIRI mouse model. This capability enhances our understanding of cellular responses, opening avenues for potential applications within disease models. The versatility of PN extends to its potential role in guiding timely monitoring and imaging of viscosity, offering valuable insights into disease progression.

Abstract
Abstract
Solute Carrier Family 25 (SLC25) is the largest family of mitochondrial membrane proteins in the human body, consisting of 53 members. Mitochondrial phosphate carriers (MPiC), cellular iron metabolism, voltage-dependent anion channels (VDAC), and oxidative phosphorylation in the SLC25 family play dominant roles in material transport, energy metabolism, etc. SLC25 family-related proteins are involved in the regulation of the progression of a variety of cancers, including colon, gastric, and lung cancers. In addition, the SLC25 family has been implicated in endoplasmic reticulum stress (ERS) and immunity. Since SLC25 family proteins are involved in cancer progression and are associated with endoplasmic reticulum stress and immunity, exploring inhibitors of SLC25 family-related proteins is essential. However, the exact mechanism of SLC25 family-related proteins involved in cancer, as well as potential targets and SLC25 inhibitors have not been reported in the literature. This article focuses on summarizing the relevance of the SLC25 family to cancer, ERS, and immunity. This review also provides a comprehensive overview of SLC25 family-related inhibitors.

Molecules 2023; 28:molecules28083455. [PMID: 37110689 PMCID: PMC10147038 DOI: 10.3390/molecules28083455] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 04/07/2023] [Accepted: 04/10/2023] [Indexed: 04/29/2023] Open
Abstract
As a vital parameter in living cells and tissues, the micro-environment is crucial for the living organisms. Significantly, organelles require proper micro-environment to achieve normal physiological processes, and the micro-environment in organelles can reflect the state of organelles in living cells. Moreover, some abnormal micro-environments in organelles are closely related to organelle dysfunction and disease development. So, visualizing and monitoring the variation of micro-environments in organelles is helpful for physiologists and pathologists to study the mechanisms of the relative diseases. Recently, a large variety of fluorescent probes was developed to study the micro-environments in living cells and tissues. However, the systematic and comprehensive reviews on the organelle micro-environment in living cells and tissues have rarely been published, which may hinder the research progress in the field of organic fluorescent probes. In this review, we will summarize the organic fluorescent probes for monitoring the microenvironment, such as viscosity, pH values, polarity, and temperature. Further, diverse organelles (mitochondria, lysosome, endoplasmic reticulum, cell membrane) about microenvironments will be displayed. In this process, the fluorescent probes about the "off-on" and ratiometric category (the diverse fluorescence emission) will be discussed. Moreover, the molecular designing, chemical synthesis, fluorescent mechanism, and the bio-applications of these organic fluorescent probes in cells and tissues will also be discussed. Significantly, the merits and defects of current microenvironment-sensitive probes are outlined and discussed, and the development tendency and challenges for this kind of probe are presented. In brief, this review mainly summarizes some typical examples and highlights the progress of organic fluorescent probes for monitoring micro-environments in living cells and tissues in recent research. We anticipate that this review will deepen the understanding of microenvironment in cells and tissues and facilitate the studies and development of physiology and pathology.
