However, the development of selective inhibitors remains challenging due to the high structural homology among PI3K isoforms. This research sought to identify new PI3Kδ inhibitors using a comprehensive computational strategy that integrates pharmacophore modeling, molecular docking, and consensus scoring. First, common feature and receptor-ligand pharmacophores were generated based on GSK2269557 and its crystal structure with PI3Kδ. The optimal common feature model (CF_10, AUC = 0.943) and the receptor–ligand model (RL_03, AUC = 0.942) demonstrated excellent discriminatory power. Then, four docking programs were benchmarked; AutoDock Vina and Glide XP exhibited superior pose reproduction and inhibitor classification (AUC &gt; 0.9). A consensus scoring function integrating pharmacophore fit values and docking scores was developed for virtual screening of the ChEMBL database, yielding several high-ranking virtual hits, with CHEMBL2216838 identified as the top candidate. Finally, 300 ns molecular dynamics simulations revealed that CHEMBL2216838 forms stable hydrogen bonds with key residues Glu826/Val828 and induces a more rigid binding mode compared to GSK2269557, enhancing interactions with Phe912. This work establishes a robust computational framework for identifying novel PI3Kδ inhibitors and presents promising candidates for further experimental validation in the treatment of inflammation-related diseases.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 4","pages":"588-602"},"PeriodicalIF":1.5,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, M NCs that possess both AIE properties and peroxidase-like activity remain rarely reported. In this study, copper nanoclusters stabilized by 3-mercaptopropionic acid (Cu NCs-MPA) were synthesized via a rapid aqueous-phase method. As-prepared Cu NCs-MPA exhibited both AIE characteristics and peroxidase-like activity. When dispersed in pure water, Cu NCs-MPA displayed minimal fluorescence emission. However, bright orange fluorescence under 365 nm UV irradiation was observed when Cu NCs-MPA were dispersed in mixtures of water and various organic solvents, including methanol (MeOH), ethanol (EtOH), ethylene glycol (EG), dimethylformamide (DMF), and dimethyl sulfoxide (DMSO). Notably, when Cu NCs-MPA were dispersed in DMSO-H₂O mixtures, fluorescence intensity increased with higher DMSO content, confirming the distinct AIE behavior of Cu NCs-MPA. Additionally, Cu NCs-MPA exhibited significant peroxidase-like catalytic activity in the H₂O₂–3,3′,5,5′-tetramethylbenzidine (TMB) reaction system, effectively catalyzing the conversion of H₂O₂ into hydroxyl radicals (•OH), which subsequently oxidized TMB to blue-colored oxidized TMB (oxTMB), resulting in increased ultraviolet absorbance at 652 nm. Upon addition of captopril, the •OH oxidized its thiol groups to form disulfide bonds (-S-S-), thereby inhibiting oxTMB formation and reducing the absorbance at 652 nm. Based on this mechanism, a highly sensitive colorimetric assay was developed for captopril detection, with a linear range of 25–250 μM and a low detection limit of 3.93 μM. Moreover, the method was successfully applied to the determination of captopril in real pharmaceutical samples, demonstrating high sensitivity, good selectivity, and rapid response.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 4","pages":"661-672"},"PeriodicalIF":1.5,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained materials were characterized by scanning electron microscopy, X-ray diffractometer (XRD), UV–visible and Fourier-transform infrared spectrometer. NiS-ZnS nanoparticles were synthesized based on the obtained NiZnAl-LDH/PVA nanocomposite by the successive ionic layer adsorption and reaction (SILAR) method. The effects of SILAR cycles, reaction parameters, and the metal ion ratio on particle size, crystal formation and structure have been extensively investigated. Some binary sulfide phases were observed in the XRD pattern of NiS–ZnS/LDH/PVA nanocomposite. The peak broadening of the metal sulfide phase is attributed to structural defects in the main lattice. The maximum absorbance band of the NiS–ZnS/LDH/PVA (Ni:Zn = 1:1) nanocomposite increased significantly in the UV–Vis spectrum because of the enhanced light-harvesting ability. It also shows incredibly low Urbach energy (<i>E</i>_<i>U</i> = 0.37 eV), which is a characteristic of disordered semiconductors. The sorption and photocatalytic degradation performance of the synthesized NiZnAl-LDH/PVA and NiS-ZnS-doped LDH/PVA nanocomposites were studied using various model pollutants under UV-C, visible light (150 W tungsten lamp), and solar irradiation. Rhodamine 6G was selected as a cationic, Ponceau 4R as an anionic, Patent Blue V as an anionic–zwitterionic dye, and 2,4-dichlorophenoxyacetic acid as a phenoxy herbicide. The sorption efficiency of NiZnAl-LDH/PVA nanocomposite is significantly high with anionic dye (97.9%) and incredibly low with cationic dyes. The sorption of cationic dyes increased significantly after sulfidation of LDH, which can be explained by three facts: the changes in surface activity, an increase in available sorption sites, and surface charge. Langmuir constant value (<i>K</i>_L = 0.01 L/mg) of the sorption of 2.4 D onto NiZnAl-LDH/PVA is close to the Langmuir–Hinshelwood constant (<i>K</i>_L–H = 0.009), which combines adsorption equilibrium with surface reaction rate.

In this work, a heterojunction WO₃/Bi₃NbO₇ was prepared by impregnation of WO₃ nanoparticles into Bi₃NbO₇ precursor followed by calcination. The prepared samples were characterized by techniques like x-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) specific surface area analysis, scanning electron microscope (SEM), transmission electron microscope (TEM), x-ray photoelectron spectroscopy (XPS), UV-vis diffuse reflectance spetrum (UV-vis DRS), total organic carbon (TOC) analysis and electrochemical test. The photocatalytic performance was evaluated by investigation of tetracycline (TC) degradation under stimulated sunlight. The results showed that the heterojunction greatly improved the photocatalytic activity of Bi₃NbO₇ under stimulated sunlight irradiation, beneficial to the effective separation of photo-generated electrons and holes. The suitable Bi/W molar ratio is necessary to construct an effective heterojunction WO₃/Bi₃NbO₇. The TC degradation efficiency of 85% was obtained on sample with Bi/W molar ratio of 2. The WO₃/Bi₃NbO₇ exhibited good reusability that TC degradation efficiency declined from 85% to 76% after five cycles of use. An S-scheme mechanism was proposed for degradation of TC on WO₃/Bi₃NbO₇ heterojunction.
