While traditional antithrombotic drugs like clopidogrel and warfarin are effective, they carry risks such as bleeding. This study uses computational techniques to explore natural compounds as safer alternatives, including ADMET analysis, molecular docking, 100-ns molecular dynamics simulations, and binding energy assessments via MM-PBSA and MM-GBSA methods. Human transglutaminase 2, an enzyme crucial to clot formation, served as the target protein. The selected 48 ligands underwent pharmacokinetic and physicochemical evaluations using SwissADME and pkCSM tools. Among these, 45 adhered to Lipinski’s rule of five, demonstrating favorable drug-like properties and promising ADMET profiles, including high intestinal absorption and blood–brain barrier penetration. Molecular docking identified robust interactions between TG2’s active site residues (TRP 241, TRP 332, and CYS 277) and two standout ligands, oleanolic acid, and ursolic acid lactone, with binding affinities of − 9 kcal/mol and − 9.4 kcal/mol, respectively, surpassing reference drugs. Extended MD simulations confirmed the stability of the ligand–protein complexes, with RMSD and RMSF analyses indicating minimal fluctuations in active site residues. MM-PBSA and MM-GBSA energy calculations revealed significant contributions from electrostatic and van der Waals interactions, supporting the observed binding stability. This study underscores the potential of oleanolic acid and ursolic acid lactone as promising antithrombotic agents. Their favorable pharmacokinetics and stable interactions with TG2 highlight their potential for developing safer, target-specific antithrombotic therapies.</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 3","pages":"1823 - 1841"},"PeriodicalIF":2.2,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668338","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}

Investigations were conducted on the use of natural sawdust (NSD) and activated sawdust (ASD) to remove BR2 dye from an aqueous medium. To chemically modify the ASD, 1 M caustic soda solution (NaOH) was used. By adding novel functional groups (–ONa) to the ASD surface, the sorption efficiency of the BR2 dye was improved. This resulted in a considerable increase in surface polarity and sorption site power. Using FTIR, EDX, and (SEM) analysis, the structure and morphology of adsorbent sawdust were examined. The batch technique generated quantitative adsorption under a range of circumstances, including initial concentration, pH, temperature, and contact time. The adsorption kinetics were investigated using two kinetic models, including pseudo first order and pseudo second order, and a pseudo second-order kinetic is the best model. Two common isotherm equations (Langmuir and Freundlich) are that were used to determine the BR2 dye adsorption isotherms on adsorbents and showed a good fit with the Langmuir model more than Freundlich’s isotherm model (<i>R</i><sup>2</sup> = 0.995). The thermodynamic assessment demonstrated the exothermic, spontaneous, and feasible nature of the BR2 adsorption onto NSD and ASD. The results clarified that a large percentage removal and the optimized conditions were (8 ± 0.01) solution pH, 19.28 mg/L initial dye concentration, adsorbent dose 0.1 g/40 ml of dye solution for NSD and ASD respectively, and 60 min adsorption time. 68.72% and 93.77% of dye were removed by NSD and ASD respectively at experimental optimum conditions. The removal price per gram of BR2 dye in 1000 m<sup>3</sup> of wastewater using ASD adsorbent was found to be 0.017$ which is very low compared to another adsorbent. The BR2 removal efficiency is still above 85% and 60% after four cycles concerning ASD and NSD respectively. Additionally, NSD and ASD are easily regenerative and reusable, suggesting that this adsorbent may have significant promise for wastewater dye adsorption. It was found that ASD removed contaminants more effectively than the other.</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 3","pages":"1689 - 1705"},"PeriodicalIF":2.2,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668071","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 inhibitory effect was directly proportional to extract concentration and inversely related to temperature. Both BE and EAE displayed optimal inhibitory efficacy at specific concentrations. At a 1000 ppm concentration, BE obtained a peak inhibition level of 87.12%, while EAE displayed an optimal inhibition of 83.32% at 900 ppm, both under a temperature of 283 K.

Biomarker analysis showed regulation of apoptosis (Caspase-3 and Caspase-9) and inflammatory (STAT3, TNF-<i>α</i>) pathways. Our results suggest that the novel 3-(2-mercapyo-phenylimino)-1,3-dihydro-indol-2-one-based ligand and its metal complexes, specifically iron (Fe (III)) and lanthanum (La (III)), hold promise as potential anticancer agents against breast adenocarcinoma cells in vitro and in vivo. Furthermore, the enhanced effectiveness of the metal complexes may be attributed to their regulation of apoptosis and inflammation-related biomarkers.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 3","pages":"1539 - 1560"},"PeriodicalIF":2.2,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668300","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}
