The development of small-molecular fluorogenic tools for the chemo-selective labeling of proteins in live cells is important for the evaluation of intracellular redox homeostasis. Dynamic imaging of human serum albumin (HSA), an antioxidant protein under oxidative stress with concomitant release of antioxidant drugs to maintain redox homeostasis, affords potential opportunities for disease diagnosis and treatment. In this work, we developed a nonfluorogenic prodrug named , by introducing -acetyl-l-cysteine (NAC) into a conjugated acceptor skeleton.

Background: Cataracts now account for the largest proportion of the global burden of blindness and vision loss. Understanding the changing trends in the global burden of cataracts over the past 30 years and the next 15 years is of clear significance for the prevention and control of cataracts in key populations. As far as we know, research on the future burden of cataracts is lacking.

Article Synopsis
  • The study aimed to assess the changes in disability-adjusted life years (DALYs) and prevalence of cataract in China from 1990 to 2019, and to predict future trends between 2020 and 2030.
  • Data was collected using the Global Burden of Diseases database, analyzing trends by age and gender using statistical software.
  • Results indicated a significant rise in DALYs and cataract cases over the years, with increasing burdens predicted, particularly affecting older women and linked to factors such as air pollution and obesity.

In this research, we developed a photoluminescent platform using amine-coupled fluorophores, generated from a single conjugate acceptor containing bis-vinylogous thioesters. Based on the experimental and computational results, the fluorescence turn-on mechanism was proposed to be charge separated induced energy radiative transition for the amine-coupled fluorophore, while the sulfur-containing precursor was not fluorescent since the energy internal conversion occurred through vibrational 2RS- (R represents alkyl groups) as energy acceptor(s). Further utilizing the conjugate acceptor, we establish a new fluorogenic approach via a highly cross-linked soft material to selectively detect cysteine under neutral aqueous conditions.

In this Letter, we report that two amines can be coupled together rapidly and quantitatively through amine-thiol scrambling using a bisvinylogous thioester conjugate acceptor under mild conditions. The resulting bisvinylogous amide conjugate acceptors can be decoupled via an ethylene diamine-induced cyclization. Four representative conjugate acceptors have been utilized in the couple-decouple reactions, which were monitored and characterized by nuclear magnetic resonance, high-resolution mass spectrometry, and UV-vis spectroscopy.

Article Synopsis
  • The article discusses a new photoluminescence platform for tracking chemical bonding processes in soft materials like hydrogels during gelation, remodeling, and degradation.
  • It highlights the use of "indanonalkenes" to monitor turn-on emission during chemical reactions involving amine derivatives, allowing for tracking fluorescence and mechanical changes.
  • The paper also describes how luminescence can visualize the transformation and degradation of hydrogels, and it proposes a photographic imaging method to quantitate these macroscopic changes, paving the way for advanced "smart" materials.

Article Synopsis
  • - A dual lock-and-key fluorescence probe was created to visualize inflammation in myocardial H9C2 cells, featuring two-photon properties and responsiveness to viscosity and hydrogen peroxide (HO).
  • - The probe operates by using a thiocarbamate spacer that allows the release of carbonyl sulfide (COS), which then converts into anti-inflammatory hydrogen sulfide (HS) through the enzyme carbon anhydrase.
  • - In experiments, the probe showed good biocompatibility and low toxicity, successfully alleviating inflammation caused by hydrogen peroxide in cells, effectively providing a method for diagnosing and treating cellular inflammatory processes.

Indicator displacement assays (IDAs) offer a unique and innovative approach to molecular sensing. IDAs can facilitate the detection of a range of biologically/environmentally important species, provide a method for the detection of complex analytes or for the determination and discrimination of unknown sample mixtures. These attributes often cannot be achieved by traditional molecular sensors i.

To achieve personalized healthcare, a quick, accurate, and high-throughput method to detect disease biomarkers is essential. In the traditional practice, mass spectrometry is one of the most powerful tools and is widely studied. However, the test of human serum usually requires complicated sample pretreatment, tedious operations, and precise condition control, especially for the detection of enzymes as biomarkers.

Hydrogen peroxide, an important biomolecule, receives earnest attention because of its physiological and pathological functions. In this Article, we present the rational design, characterization, and biological application of a mitochondria-targetable NIR fluorescent sensor, Mito-NIRHP, for hydrogen peroxide visualization. Mito-NIRHP utilizes a unique reaction switch, α-ketoamide moiety, to turn on a highly specific, sensitive, and rapid fluorescence response toward hydrogen peroxide coupled with the intramolecular charge transfer strategy.
