Quantification of binding capacity of natural products to target proteins by sensors integrating SERS labeling and photocrosslinked molecular probes. Anal Chim Acta 2024; 1317:342911. [PMID: 39030011 DOI: 10.1016/j.aca.2024.342911] [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: 02/26/2024] [Revised: 06/03/2024] [Accepted: 06/24/2024] [Indexed: 07/21/2024]
Abstract
Natural products-based screening of active ingredients and their interactions with target proteins is an important ways to discover new drugs. Assessing the binding capacity of target proteins, particularly when multiple components are involved, presents a significant challenge for sensors. As far as we know, there is currently no sensor that can accomplish high-throughput quantitative analysis of natural product-target protein binding capacity based on Raman spectroscopy. In this study, a novel sensor model has been developed for the quantitative analysis of binding capacity based on Surface-Enhanced Raman Spectroscopy (SERS) and Photocrosslinked Molecular Probe (PCMP) technology. This sensor, named SERS-PCMP, leverages the high throughput of molecular probe technology to investigate the active ingredients in natural products, along with the application of SERS labelling technology for target proteins. Thus it significantly improves the efficiency and accuracy of target protein identification. Based on the novel strategy, quantitative analysis of the binding capacity of 20 components from Shenqi Jiangtang Granules (SJG) to α-Glucosidase were completed. Ultimately, the binding capacity of these active ingredients was ranked based on the detected Raman Intensity. The compounds with higher binding capacity were Astragaloside IV (Intensity, 138.17), Ginsenoside Rh2 (Intensity, 87.46), Ginsenoside Rg3 (Intensity, 73.92) and Ginsenoside Rh1 (Intensity, 64.37), which all exceeded the binding capacity of the positive drug Acarbose (Intensity, 28.75). Furthermore, this strategy also performed a high detection sensitivity. The limit of detection for the enzyme using 0.1 mg of molecular probe magnetic nanoparticles (MP MNPs) was determined to be no less than 0.375 μg/mL. SERS-PCMP sensor integrating SERS labeling and photocrosslinked molecular probes which offers a fresh perspective for future drug discovery studies. Such as high-throughput drug screening and the exploration of small molecule-target protein interactions in vitro.

Abstract
The activation of inflammasome leads to secretion of inflammatory factors and cell pyroptosis that are critical in the pathogenesis of various chronic and acute inflammatory diseases. Recruitment and activation of caspase-1 is a marker of inflammasome activation. However, there is still lack of real-time and efficient methods to detect the activation of inflammasome, especially in vivo. Herein, we developed two activatable caspase-1-responsive fluorescence biosensors, WEHD-HCy and YVAD-HCy, to specifically monitor the activation of inflammasome in vivo. Our in vitro study demonstrated that WEHD-HCy and YVAD-HCy can sensitively and specifically respond to caspase-1 activation. Moreover, these biosensors can efficiency and specifically activated in the common inflammatory disease model, including inflammatory bowel disease, Salmonella infection, and acute arthritis. In particular, WEHD-HCy is more advantageous than YVAD-HCy to specifically image of caspase-1 activity both in vitro and in vivo. These caspase-1-responsive fluorescence biosensors provide an efficient, rapid, and in situ tool for monitoring inflammasome activation, and have the potential to be suitable for clinical diagnosis of various inflammatory diseases associated with inflammasome activation.

Abstract
Cell death is closely related to various diseases, and monitoring and controlling cell death is a promising strategy to develop efficient therapy. Aggregation-induced emission luminogens (AIEgens) are ideal candidates for developing novel theranostic agents because of their intriguing properties in the aggregate state. The rational application of AIE materials in cell death-related research is still in its infancy but has shown great clinical potential. This review discussed the research frontier and our understanding of AIE materials in various subroutines of cell death, including apoptosis, necrosis, immunogenic cell death, pyroptosis, autophagy, lysosome-dependent cell death, and ferroptosis. We hope that the new insights can be offered to this growing field and attract more researchers to provide valuable contributions.

Abstract
Owing to the high sensitivity and high spatial resolution, fluorescence (FL) imaging has been widely applied for visualizing biological processes. To gain insight into molecular events on deeper tissues, photoacoustic (PA) imaging with better deep-tissue imaging capability can be incorporated to provide complementary visualization and quantitative information on the pathological status. However, the development of activatable imaging probes to achieve both FL and PA signal amplification remains challenging because the enhancement of light absorption in PA imaging often caused the quenching of FL signal. Herein, we first developed a caspase-3 enzyme activatable nanoprobe of a nanogapped gold nanoparticle coated with AIE molecule INT20 and DEVD peptides (AuNNP@DEVD-INT20) for tumor FL and PA imaging and subsequent imaging-guided radiotherapy. The nanoprobe could interact with GSH and caspase-3 enzyme to liberate INT20 molecules, leading to AIE. Simultaneously, the in situ self-assembly of AuNPs was achieved through the cross-linking reaction between the sulfhydryl and the maleimide, resulting in ratiometric PA imaging in tumor. Remarkably, the nanoprobe can generate richful ROS for cancer radiotherapy under X-ray irradiation. The platform not only achieves the aggregation-induced FL and PA signal enhancement but also provides a general strategy for imaging of various biomarkers, eventually benefiting precise cancer therapy.

Abstract
During our continuous investigation of natural, herbal inhibitors of microglial over-activation in the Euphorbiaceae family, two plants of the Vernicia genus showed remarkable inhibitory effects on nitric oxide (NO) production in over-activated microglia. In this study, bioactivity-guided phytochemical research on the active fraction of the roots of V. montana was carried out. As a result, seven undescribed terpenoids and lignans, together with thirty-one known components, were isolated and identified using comprehensive spectral analysis. All the identified compounds were evaluated for their inhibitory effects on NO production in lipopolysaccharide-stimulated BV-2 cells. Combined with our previous research on the Vernicia genus, the effective material basis of different plants and medicinal components was analyzed systematically.

However, there is still a lack of critical reviews that compare the merits and shortcomings of these biosensors from a pharmaceutical point of view. This contribution presents a critical and up-to-date overview on the recent progress of tailored biosensors, including surface plasmon resonance, fluorescent, photoelectrochemical, and electrochemical systems with emphasis on their mechanisms and applications in drug screening, efficacy assessment, and toxicity evaluation. Multiple functional nanomaterials have also been incorporated into the biosensors. Representative examples of each type of biosensors are discussed in terms of design strategy, response mechanism, and potential applications. In the end, we also compare the results and summarize the major insights gained from the works, demonstrating the challenges and prospects of biosensors-assisted drug discovery.

Abstract
High-throughput screening facilitates the rapid identification of novel hit compounds; however, it remains challenging to design effective high-throughput assays, partially due to the difficulty of achieving sensitivity in the assay techniques. Among the various analytical methods that are used, fluorescence-based assays dominate owing to their high sensitivity and ease of operation. Recent advances in activity-based sensing/imaging have further expanded the availability of fluorescent probes as monitors for high-throughput screening of result outputs. In this study, we have reviewed various activity-based fluorescent probes used in high-throughput screening assays, emphasizing their structure-related working mechanisms. Moreover, we have explored the possibility of the development of additional and better probes to boost hit identification and drug development against various targets.

Abstract
We describe a novel green-emitting tetraphenylethylene-dicyanomethylene-4H-pyran (TPE-DCM) based fluorescent probe (TD-1). Conjugating TPE and DCM moieties allowed TD-1 to display high selectivity for thiophenol with excellent AIE properties in aqueous solution. Nevertheless, the poor water solubility of the hydrophobic structure resulted in a weak and unstable emission intensity. The non-covalent self-assembly of TD-1 with a TPE glycocluster (TPE2S) led to a largely improved water solubility producing a reliable and stable sensing system. The corresponding glyco-probe could sensitively detect exogenous thiophenol concentrations in PBS buffer or environmental water samples.

Abstract
The advances in bioinformatics and biomedicine have promoted the development of biomedical imaging and theranostic systems to respectively extend the endogenous biomarker imaging with high contrast and enhance the therapeutic effect with high efficiency. The emergence of biomacromolecule-functionalized aggregation-induced emitters (AIEgens), utilizing AIEgens, and biomacromolecules (nucleic acids, peptides, glycans, and lipids), displays specific targeting ability to cancer cell, improved biocompatibility, reduced toxicity, enhanced therapeutic effect, and so forth. This review summarizes the rational design of biomacromolecule-functionalized AIEgens and their biomedical applications in recent ten years, including high-resolution optical imaging of cell, tissue, and small animal model with low background; the biomarker detection for early diagnosis and prognosis; the delivery and monitoring of prodrugs; image-guide photodynamic therapy and its combination with chemotherapy. Through illustrating their functional mechanisms and application, it is hoped that this review would open up a completely new train of research thought for attracted researchers in various fields.

Abstract
The caspase cascade is an ensemble of very important signaling molecules that plays a critical role in cell apoptosis. Real-time monitoring of the upstream and downstream activation relationships of the caspases in the signal pathway is of great significance for understanding the regulatory mechanisms of these signaling molecules in the development of various diseases. Herein, a multicolor fluorescent nanoprobe, GNP-Se-Casp, has been developed based on Au-Se bonding for real-time in situ monitoring caspase- (casp-) 3, 8, and 9 during cell apoptosis. In the real-time fluorescence imaging of apoptotic HeLa cells induced by staurosporine using GNP-Se-Casp, the fluorescence signals corresponding to casp-8 and casp-9 sequentially turn on, followed by the appearance of the fluorescence of casp-3, which visualizes the upstream and downstream relationships of casp-3, -8, and -9. Thus, GNP-Se-Casp is an effective tool for real-time in situ monitoring of caspase cascade activation in the apoptosis process of tumor cells. This design strategy is easily adaptable to in situ detection of other signal molecules, especially those with upstream and downstream activation relationships.

Abstract
Fluorescent natural products are a rich source of drugs and chemical probes, but their innate fluorescence can interfere with fluorescence-based screening assays. Caspase-8 is a key player in apoptosis, its inhibition having been found to be beneficial for treatment of inflammatory and neurodegenerative diseases. Small-molecular inhibitors of caspase-8 remain sparsely reported, however. In this study, we firstly developed a light-up probe based on an AIEgen and capable of targeting caspase-8. This fluorescent dye has a Stokes shift of 200 nm, which could allow the innate fluorescence signals of natural products to be avoided. On screening a library of 86 fluorescent natural products, we found for the first time that gossypol showed potent inhibition of caspase-8 in vitro and in situ. This unique light-up probe, coupled with colored natural products, could represent an efficient approach to hit discovery for druggable targets.

Abstract
Formaldehyde (FA), as a reactive carbonyl species and signaling molecule, plays an important role in living systems. Here, an FA-responsive probe with fast response and great selectivity is designed based on aggregation-induced emission. The probe is prepared by functionalizing tetraphenylethene (TPE) with two amine groups. FA is detected based on the solubility differences between the amine-functionalized TPE and the corresponding Schiff bases after reaction with FA. The probe exhibits a limit of detection of 40 nM and a response time of ∼90 s. Furthermore, its ability to detect both endogenous and exogenous FA is demonstrated in living cells with high specificity. Moreover, the probe is also introduced to image endogenous FA in real time with fast response. These results suggest that our probe holds great potential for tracking FA in living systems under various physiological conditions as well as related biomedical applications.
