Despite experimental identification of numerous anti-inflammatory peptides, the development of peptide-based drugs remains expensive, time-consuming, and labor-intensive. Small molecules offer higher stability compared to peptides, owing to their chemical synthesis or natural sources. Consequently, there is an urgent need to develop advanced machine learning (ML) methods utilizing a large-scale dataset consisting of experimentally acquired small molecule to enhance precision and efficiency. This study introduces a predictive ML-method, named InFlamPred (Anti-inflammatory Small Molecule Predictor), tailored for anti-inflammatory small molecules. The proposed ML classifier facilitates compound screening in inflammatory diseases. We trained five different ML classifiers—RF, KNN, LGBM, DT, and XGB achieving an overall accuracy ranging from 61 to 75%. Notably, the LGBM, RF, and XGB models demonstrated strong performance on the training dataset, with XGB maintaining high accuracy and robustness on the test dataset, achieving an accuracy of 75% and an AUC of 81%. When evaluated on an external validation dataset consisting of 80 compounds (equally distributed between active and inactive classes), the XGB model effectively identified all active and inactive molecules. These results highlight the reliability and generalizability of the proposed ML approach in accurately predicting small molecules with anti-inflammatory potential.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 9","pages":"5957 - 5969"},"PeriodicalIF":2.5,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144918433","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}

The optimal morphology for L@ihNFs was determined to be 0.05 mg/mL. To obtain the optimum activity, conditions were explored pH values ranging from 6 to 12 and temperatures between 30 and 80 °C. Both the free form and L@ihNF exhibited higher activity in alkaline conditions, with a significant decrease in activity observed at pH 11 and 12. L@ihNF showed superior activity and remarkable compatibility compared to the free enzyme in the presence of various commercial liquid/powder detergents and surfactants. Moreover, it displayed over a twofold increase in activity in some oils/fat/waste oils. The reusability of the synthesized L@ihNF was examined in 10 cycles, and it was observed that it still showed 58% activity at the end of the 8th cycle, which is a good indicator of reusability.

Conventional corrosion inhibitors often involve toxic and non-biodegradable chemicals, leading to environmental concerns. To address this, the present study explores an environmentally benign method for the synthesis of cobalt nanoparticles (CoNPs) using Erythrina crista-galli leaf extract, which acts as a natural reducing and stabilizing agent. The novelty of this work lies in the green synthesis of CoNPs with enhanced anticorrosive activity, which surpasses traditional methods by eliminating hazardous reagents and minimizing environmental impact. Synthesis parameters such as extract concentration, pH, precursor-to-extract ratio, reaction temperature, and time were optimized to achieve nanoparticles with improved stability, morphology, and crystallinity. The synthesized CoNPs were thoroughly characterized using UV–visible spectroscopy, FTIR, DLS, Zeta potential analysis, SEM–EDX, and XRD, confirming the formation of well-dispersed nanoparticles with controlled size and shape. Electrochemical studies using potentiodynamic polarization and weight loss techniques revealed a maximum corrosion inhibition efficiency of 90.08% for CoNPs in 0.5 M HCl solution, demonstrating their strong barrier effect on steel surfaces. These findings underscore the potential of green-synthesized CoNPs as a sustainable and highly efficient alternative to synthetic corrosion inhibitors for industrial applications.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 9","pages":"5875 - 5897"},"PeriodicalIF":2.5,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144918444","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}

So in some rural and developing countries, the public does not get the proper mode of shifting due to a lack of transportation facilities. Private vehicles like auto-rickshaws, vans, jeeps, and minibuses are informally overloaded with the public, and transportation is done.

This informal way of transportation leads to environmental pollution and health effects by emitting air pollution. Using different fuels in vehicles and overloading the passengers in informal transportation lead to unsafe modes.
