In this study, redox-responsive glutathione-extended WPUs were developed to enable targeted drug release in the reductive tumour microenvironment. Three WPUs with increasing hydrophilic character were synthesized using a PCL-PEG-PCL triblock copolymer, isophorone diisocyanate and 2,2-bis(hydroxymethyl)propionic acid (DMPA) as an emulsifier, allowing efficient water dispersion of hydrophobic polyurethane segments. A purification process was developed to replace triethylammonium counterions with sodium ions, resulting in a dried polymer easily redispersible in water through autoclaving. Membranes produced from WPU dispersions demonstrated excellent hydrolytic stability and high hydrophilicity. Effective paclitaxel (PTX) loading (40 μg/mg) was achieved during autoclaving and controlled drug release was observed, with increased release rates under reductive conditions. Under homeostatic conditions, less than 20 % of the loaded PTX was released over 16 days, while in a reductive tumour-like environment, the release rate increased to 40 %, indicating strong redox responsiveness. Enhanced cytotoxicity was also observed in HCT-116 cells under simulated reductive conditions. This redox-triggered drug release, responsive to high glutathione levels of tumours, highlights the potential of WPUs for localized cancer therapies. These biomaterials offer a promising platform for developing injectable or implantable WPU-based systems for peritumoral or intratumoral delivery of anticancer drugs, reducing off-target effects and improving treatment efficacy.</div></div>","PeriodicalId":315,"journal":{"name":"European Polymer Journal","volume":"226 ","pages":"Article 113759"},"PeriodicalIF":5.8,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143128360","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}

Interestingly, when alkane alcohols were applied as polar solvents, increasing the carbon chain length (which gradually decreases polarity) results in a transition in particle morphology from spherical particles to Janus particles with only chemical environmental asymmetry, and then to dual Janus particles. However, when benzene series were utilized as non-polar solvent, the particles morphology changed from spherical particles to Janus particles with only structural asymmetry as the number of methyl groups on the benzene ring increases.
