Article Abstract

An iminocoumarin and tetraphenylethylene compound that exhibits aggregation-induced emission (AIE) and a significant Stokes shift (Δλ = 135 nm) in THF was created via the Knoevenagel condensation method. TPICBT could also be used as a ratiometric near-infrared fluorescent probe for the naked color identification of F and HS. It showed a large red shift (˃ 90 nm), good selectivity, and anti-interference. Test strip detection and cell imaging had both been accomplished using the probe. In addition, the probe could conveniently detect HS produced during food spoilage without laboratory instruments.

Adenosine triphosphate (ATP) is a critical biomolecule in cellular energy metabolism, with abnormal levels in the bloodstream linked to pathological conditions such as ischemia, cancer, and inflammatory disorders. Accurate and real-time detection of ATP is essential for early diagnosis and disease monitoring. However, conventional biochemical assays and other techniques suffer from limitations, including invasive sample collection, time-consuming procedures, and the inability to provide dynamic, monitoring.

Salicylic acid (SA) is a critical phytohormone involved in plant growth, development, and defense responses, making its precise quantification essential for both agricultural management and environmental monitoring. Here, we report a novel label-free near-infrared aptasensor (NIRApt) for the rapid and sensitive detection of SA, utilizing a rationally selected triphenylmethane (TPM) dye. Through systematic screening, ethyl violet (EV) was identified as the optimal fluorophore, showing pronounced fluorescence enhancement upon binding to a SA-specific aptamer.

Background: The development of specific fluorescent probes for cancer cell discrimination holds significant promise for advancing cancer diagnostics. Conventionally, these probes operate by translating differences in biomarkers or microenvironmental factors into variations in whole-cell fluorescence intensity. However, this dominant, intensity-based strategy is highly susceptible to extraneous fluctuations arising from probe concentration, illumination instability and complex intracellular environment.

Background: Lung ischemia-reperfusion injury (LIRI) is a pathological condition characterized by aggravated oxidative-inflammatory tissue damage that occurs upon blood flow restoration after ischemia. LIRI can lead to severe complications, including primary graft dysfunction in lung transplants and multi-organ failure. However, current treatments remain limited.

Prolyl endopeptidase (PREP) drives neurodegenerative diseases through dual mechanisms involving enzymatic activity and protein-protein interactions (PPIs), yet current inhibitors predominantly target single pathways Prolyl endopeptidase (PREP) fuels neurodegeneration via enzymatic cleavage and pathological PPIs, yet current inhibitors usually target only one facet. In this study, leveraging our developed high-sensitivity and high-specificity near-infrared fluorescent probe Z-GP-ACM, we established and validated a screening platform for PREP inhibitors with mouse brain S9 instead of the human recombinant PREP. Screening a library of 110 natural compounds identified a series of flavonoid derivatives (FV64-FV68) as potent PREP inhibitors, with FV67 and FV68 exhibiting particularly strong inhibition (IC values of 0.
