Stability studies were carried out for both drugs using different five degradation conditions. The chromatographic separation was achieved using BDS Thermo-Hypersil C8 (150 mm x 4.6 mm, 5 μm) column and hybrid micellar mobile phase composed of 50 gm of sodium lauryl sulphate in 500 mL purified water with 100mL of 2-Propanol and 3 mL triethylamine and then completed with purified water to 1000mL, and the mobile phase pH was 3.3. The (PDA) detector was used at 223 nm, 40 °C column temperature, 1mL/min flow rate and 20µL injection volume. The retention times of DAP and MET were (5.37 ± 0.4 min) and (7.64 ± 0.2 min), respectively. Linearity was constructed in ranges of (0.2-7 µg/mL) for DAP and (50-700 µg/mL) for MET. Mean percentage recoveries of DAP and MET were 99.88%±0.53 and 100.034%±0.60, respectively indicates good accuracy. The developed approach was validated according to ICH guidelines and efficiently applied for the analysis of DAP and MET in Dexigloflozin plus® 5/500 tablets. For the greenness assessment the analytical eco-scale, Complex MoGAPI and AGREE methods were applied.","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":"175"},"PeriodicalIF":4.3,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12181907/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents the synthesis of 2D CuO/reduced graphene oxide (rGO) nanocomposite via probe sonication, designed to synergistically enhance the photocatalytic reduction of Cr(VI) to less toxic Cr(III). The nanocomposite was meticulously characterized using XRD, HRTEM, FESEM, XPS, and UV-Vis diffuse reflectance spectroscopy. Structural analysis confirmed the formation of CuO nanosheets (average size: 396 nm, thickness: 6 nm) integrated with rGO, where the rGO acted as an electron acceptor, mitigating charge recombination. XPS revealed Cu²⁺ in CuO and Cu(OH)₂ phases, while FTIR confirmed interfacial interactions between CuO and rGO via oxygen functional groups. The CuO/rGO composite exhibited a reduced bandgap (1.35 eV → lower with rGO incorporation) and broad visible-light absorption, critical for photocatalytic activity. Under visible light, the composite achieved a remarkable 75% Cr(VI) reduction efficiency within 180 min triple that of pure CuO (25%) with a rate constant (0.007 min⁻¹) sevenfold higher. This enhancement is attributed to rGO role in facilitating electron transfer from CuO conduction band to its LUMO, minimizing electron-hole recombination. The composite demonstrated excellent recyclability over three cycles without significant efficiency loss. These findings underscore the potential of CuO/rGO as a robust, sustainable photocatalyst for environmental.","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":"174"},"PeriodicalIF":4.3,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12180283/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, tri-functionalized (fluorescent, antimicrobial and UV-protection) cotton textiles were designed by immobilization of heterocyclic compounds based on quinazoline derivatives (QDs). Firstly, four quinazoline derivatives (QD-1 = H, QD-2 = O-CH3, QD-3 = Cl, QD-4 = H [without COOH]) were synthesized for the first time starting from 2-(chloromethyl) quinazoline-4(3H)-one. The chemical structure of all obtained QDs were investigated by NMR (1H & 13C) and infrared spectroscopy, in addition to the measurement of melting points, yields and emission spectra. Secondly, the synthesized QDs were immobilized within cotton textile, while cotton was per-activated by interaction with cationic reagent. The modified textiles (QDs@Q-cotton) gained dark yellow color. The QDs@Q-cotton emitted greenish radiation and showed intense emission fluorescence at 485-521 nm. Good-very good (UPF = 23.6-32.8) and good (21.3-25.8) UV protection was respectively shown for QDs@Q-cotton before and after 10 washings. The protection from UV radiation for QDs@Q-cotton is attributed to the reflection of UV radiation by effect of QDs micro particles which deposited within the cotton matrix. The modified textiles exhibited antimicrobial action against S. aureus and E. coli bacteria, while the mortality was 79.9-89.1% and 69.7-76.2% before and after 10 washings, respectively. The antibacterial activity of the QDs@Q-cotton fabrics is attributed to the QDs skeleton. The highest antibacterial action for QD-3@Q-cotton is related to the chlorine derivative. The multi-functionalized textile with good durability could be successfully employed in the military/soldiers clothes.","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":"173"},"PeriodicalIF":4.3,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12180280/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular docking, molecular dynamics (MD) simulations, and MM/PBSA free energy calculations identified glucoerucin (-17.18 ± 3.51 kcal/mol) and gluconasturtiin (-13.54 ± 1.79 kcal/mol) as the strongest binders, with stable interactions involving Phe280 and Phe196 through π-π stacking. Potential Energy Landscape (PEL) analysis further confirmed that these two compounds occupied the most stable low-energy conformational states, reinforcing their favorable binding to PTP1B. In vitro enzyme inhibition assays provided experimental validation that glucoerucin (IC₅₀ = 6.07 ± 0.69 µM) and gluconasturtiin (IC₅₀ = 7.65 ± 0.45 µM) demonstrated the strongest inhibitory effects, comparable to ursolic acid (IC₅₀ = 7.11 ± 0.95 µM). Enzyme kinetics revealed a non-competitive inhibition mechanism, with Ki values of 6.29 µM and 7.02 µM, suggesting allosteric regulation. ADMET analysis indicated good solubility and metabolic stability but limited oral bioavailability due to low gastrointestinal (GI) absorption. These findings highlight glucoerucin and gluconasturtiin as promising natural PTP1B inhibitors, warranting further optimization for therapeutic applications in type 2 diabetes management.","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":"169"},"PeriodicalIF":4.3,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12180191/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
