Endogenous antioxidants actively scavenge free radicals and prevent oxidative stress. Pesticides can affect antioxidant activities. However, molecular interactions between the pesticides and endogenous antioxidants are not clear. Hence, objective of the present study is to dissect the intermolecular interactions between the widely-used pesticides (4,4′-dichlorodiphenyldichloroethylene, 4,4′-DDE; imidacloprid, IMD; lambda-cyhalothrin, CYH; malathion, MAL) and major antioxidant enzymes (Glutathione peroxidase-4, Glutathione S-Transferase, Catalase, Glutathione reductase, Superoxide dismutase-1) that might be responsible for altered enzyme activities and induction of oxidative stress. The binding affinity analysis using AutoDock vina and Discovery Studio Visualizer was conducted to unveil the potential intermolecular interactions between the pesticides and antioxidants. In the results, 4,4′-DDE, IMD, CYH, and MAL interacted with the antioxidants through stable hydrogen bonds, carbon-hydrogen bonds, van der Waals, and other hydrophobic interactions. Additionally, considerable binding affinities between the pesticides and enzymes were noted. ADME analyses have also revealed that the majority of pesticides can cross GI, exhibit low to high water solubility, and follow Lipinski's rule. Hence, results of the present study suggest that pesticides can potentially interact with antioxidants to modulate their catalytic activity and induce oxidative stress.</div></div>","PeriodicalId":100594,"journal":{"name":"Green Analytical Chemistry","volume":"12 ","pages":"Article 100228"},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Banknote dust represents the most eligible sample to ascertain the circulation of drugs of abuse. Prevalence measures of sociological interest, provided by analysing their traces on banknote dust, are less affected by the variability of their concentrations in each bill because banknote dust represents an averaged sample of high statistical significance.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;A simple banknote dust (10.0 ± 0.1 mg) extraction made use of 10 ml of a green extractant, comprising 98 % water, 2 % ethanol, and 0.1 % formic acid. A UHPLC&lt;img&gt;HRMS system with ethanol as the organic modifier was used to develop and optimize the chromatographic method; a stable isotope labelled internal standard for each analyte was used to compensate matrix effects and possible losses. The Levene test, Mandel's test, and Shapiro-Wilk's test were used to obtain the best calibration model. The Green Analytical Procedure Index (GAPI), the Analytical GREEnness Metric Approach (AGREE), the and the Eco-scale were used to assess the greenness of the method.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;Going green (AGREE score 0.83/1, Eco-Scale score 88/100) limits shortcomings due to the use of classical organic solvents in the extraction step and improves the chromatographic outcome. The linear weighted models gave limits of detections (LODs) ranging from 0.7 (3,4-Methylenedioxyamphetamine, MDA) to 3.9 ng/ml (Tetrahydrocannabinol, THC). For cocaine, they were lower than previously reported. For other analytes, no comparison can be provided because they were never analyzed in banknote dust. Intra-day and inter-day precision and accuracy were much better than those recommended by guidelines. The developed method was applied to 5 banknote dust samples from local banknote counter machines and 4 dust samples of different origins. No illicit drugs were found except cocaine in banknote dust. Its concentration ranged only one order of magnitude, from 2.76E+02 to 4.01E+03 mg of cocaine per gram of banknote dust, in agreement with previous results obtained with methanol as an extractant and organic modifier.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions and perspectives&lt;/h3&gt;&lt;div&gt;The greenness of the methods has many intrinsic merits for the environment, chromatographers and the chromatographic outcome.
