In this work, we report the development and optimization of a low-cost, iron-recoverable, and reconstitutable Lewis–Brønsted aqueous solution (LBAS) system for the selective depolymerization of post-consumer PET and PA66 wastes. The method employs a recyclable reaction medium and operates under mild conditions (150 °C, 2 h), achieving high monomer yields with excellent selectivity. The resulting terephthalic acid, adipic acid, and hexamethylenediammonium chloride were efficiently recovered and purified using straightforward separation techniques, whereas ethylene glycol was recovered as a stream suitable for purification by conventional industrial methods. A proof-of-concept experiment confirmed that PET and PA66 can also be depolymerized in the same medium, even though cross reactions between adipic acid and ethylene glycol prevent the quantitative monomer recovery. Therefore, mixed PET/PA66 feeds require prior separation to recover the individual monomers effectively. Overall, results demonstrate a scalable and environmentally benign approach for the chemical recycling of PET and PA66, contributing to a more sustainable plastic lifecycle and circular materials economy.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 10","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190334","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}

In contrast, Zn complexes with ligands capable of reducing intracellular reactive oxygen species (ROS) may exert antitumor effects through a reductive-stress mechanism. Herein, we report the synthesis and characterization of a Zn–troxerutin complex, its interaction with bovine serum albumin (BSA), and its anticancer activity. This study aims to correlate the chemical and biological properties of the complex after replacing a redox-active metal ion with a redox-inactive one. The Zn–troxerutin complex exhibited the same coordination mode and 1:1 metal-to-ligand stoichiometry as the VO analog. It showed dose-dependent antiproliferative activity at higher concentrations in A549, MDA-MB-231, and HCT-116 cancer cells, while reducing intracellular ROS. In HCT-116 cells, reductive stress was associated with increased glutathione (GSH) levels and mitochondrial membrane depolarization. The complex displayed greater anticancer efficacy than free troxerutin and selectivity toward cancer cells over normal HEK293 cells. BSA binding studies yielded positive ΔH and ΔS values, indicating that hydrophobic interactions drive complex formation, with binding constants within the optimal range for drug transport. These findings highlight Zn–troxerutin as a promising anticancer agent acting through reductive-stress pathways.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 10","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178257","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}

This multiscale framework combines atomistic sampling with real-space descriptors, enabling the dynamic characterization of hydrogen bonding, dispersion forces, steric effects, and local electronic stabilization trends along the permeation pathway. As a proof of concept, we analyze the supramolecular nanosolvation environment of cisPt at finite temperature in two representative states: bulk aqueous solution and membrane center, corresponding to the maximum of the potential of mean force (+16 kcal mol−1). The combined amIGM/GLED approach reveals how the nature and spatial distribution of drug–water interactions evolve in response to the local membrane environment, providing mechanistic insight into the electronic and supramolecular factors that shape the free-energy landscape of passive permeation.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 10","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13661178/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we describe the selective alcoholysis of PLA promoted by a commercial titanium alkoxide and a phenoxy-imine pyridine zinc complex using various diols, leading to the formation of novel lactyl-based intermediates that were employed in subsequent polycondensation reactions with dicarboxylic acids. Alcoholysis reaction of PLA in the presence of ethylene glycol, 1,4-butanediol, cis-2-butene-1,4-diol and 3-allyloxy-1,2-propanediol afforded novel lactyl-containing diols, which were successfully reacted with adipic acid to produce a series of novel copolyesters. Structural characterization by one- and two-dimensional NMR spectroscopy confirmed the effective incorporation of lactyl units into the polymer backbones. Thermal analyses revealed that the introduction of lactyl moieties influences the crystallinity and thermal behavior of the resulting materials, generally leading to amorphous polymers. This approach demonstrates a straightforward and versatile route for the valorization of PLA waste into novel functional building blocks for the synthesis of potentially biodegradable polyesters with a variety of chemical features.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 10","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13654598/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most current electro-Fenton (EF) processes still rely on the use of Fe2+ and oxidizing agents, and the secondary pollution problem caused by metal ion leaching resulting therefrom has not yet been effectively addressed. Herein, we report a dual-system four-electrode EF cell that requires no addition of chemical reagents. The system employs a 300-nm-thick NiFeMnCu (NFMC) thin film, which not only functions as an OER collector for oxygen generation from both Anode I and Anode II, but also serves as a working electrode with a two-electron pathway to produce H2O2 through the electrochemical reduction of O2 at Cathode I. Furthermore, by integrating the Cathode II, NFMC cathode for the second-step sequential electrocatalytic reaction, the generation of H2O2 and its conversion to ·OH can be achieved. This catalytic system can effectively avoid problems such as metal sludge accumulation. When cefadroxil is used as the target pollutant, its removal can be completed within 30 min. Owing to the adoption of low-cost, durable, and scalable electrode materials, this process possesses high feasibility for practical application.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 10","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149101844","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}
