While enzymatic degradation and membrane technologies have been studied separately for OP remediation, there is a lack of comprehensive research on the synergistic integration of enzyme-based catalysis with membrane systems. This review addresses this gap by analyzing how enzyme immobilization onto membrane supports enhances the efficiency, stability, and reusability of organophosphorus (OP) degradation processes. We compare various enzyme immobilization strategies (adsorption, covalent bonding, crosslinking) and assess their respective benefits and challenges. Additionally, we introduce a new framework aligning membrane-supported enzyme systems with specific OP decomposition challenges, such as enzyme deactivation and improving continuous-flow performance. Furthermore, this review highlights emerging trends, such as the integration of nanostructured materials like metal-organic frameworks (MOFs) and carbon nanotubes (CNTs) into membranes. These hybrid systems enhance catalytic degradation and offer filtration capabilities, providing a dual advantage over free enzymes or powdered nanomaterials. Enzyme-based membranes enhance enzyme stability, reusability, and operational convenience—particularly in continuous-flow systems—while also capturing particulate contaminants. By exploring enzyme–MOF–membrane composites, we propose innovative solutions for OP remediation in civilian and military applications. This work presents innovative perspectives on enzyme-based membrane technologies, offering efficient, scalable, and environmentally sustainable methods for OP detoxification. Future research should focus on developing integrated, real-time monitoring technologies to further enhance the practicality and scalability of these systems.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"15 ","pages":"Article 102298"},"PeriodicalIF":2.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143912822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, IC<sub>50</sub> values for the gaillardin treatment of SKOV3 cells were calculated.

The time-PCR method was used to measure the gene transcript amount of apoptosis markers CASP3, CASP8, CASP9, BAX, BCL2, STAT3, and JAK2. The protein levels of the markers mentioned above were semiquantified using western blotting. Gaillardin significantly inhibited the proliferation of SKOV3 cells compared with the controls. Moreover, the gaillardin-treated SKOV3 cells underwent apoptotic cell death in comparison to the untreated cell line. The results of real-time PCR analysis unraveled that gaillardin treatment significantly upregulated the expression of CASP3, CASP8, CASP9, and BAX but downregulated BCL-2 with no influence on the expression levels of STAT3 and JAK2 transcripts. This sesquiterpene had identical effects on the protein expression of caspases, Bax, and Bcl2. However, it downregulated the phosphorylated forms of JAK2 and STAT3 proteins.
