In this study, four new fluorine-substituted azo-azomethines (4a–d), containing groups such as ─CF₃ and ─OCF₃, were successfully synthesized in high yields. Their in vitro antioxidant activities were evaluated using the CUPRAC method, and the results indicate that all compounds demonstrated higher TEAC values compared to the standard antioxidant Trolox. Notably, compound 4d exhibited the highest value of 2.22. A comparative analysis indicated that the antioxidant activity was influenced not only by the presence of fluorine-based substituents but also by the number of hydroxyl (─OH) groups in their structures. The ADMEt properties were also assessed, revealing that the synthesized compounds adhered to Lipinski's rule of five. Additionally, molecular docking studies were performed to examine various biological activities, targeting specific proteins involved in disease mechanisms. The findings revealed that; Among the compounds, the 4b-2XIR complex displayed the highest docking score of −11.0 kcal/mol, indicating strong binding affinity. These findings suggest that the synthesized azo-azomethine compounds have significant potential as drug candidates for the treatment of specified diseases.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 12","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707612","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 results have shown that the thickness, morphology, and roughness of films prepared in the presence of transition metal cations are not significantly different. In contrast, these properties varied for multilayers prepared in the presence of alkaline earth metal cations. The difference in the ion-specific behavior of these two classes of cations was explained by the difference in the hydration of these ions and by the bridging of polyelectrolyte chains with ions. While transition metal cations have similar hydration parameters, alkaline earth cations have different degrees of hydration and a better ability to form bridging bonds with polyelectrolyte monomers.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 12","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/slct.202501185","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydrothermal method was employed to fabricate a Ni-MgAl LDH with GK.

The composite's swelling indices under varying conditions and loading parameters, such as pH and drug concentration, were explored. It is observed that an increase in the percentage of ciprofloxacin (Cip) drug loading as the medium shifts from mildly acidic to neutral. Different kinetic models, such as first-order, zero-order, Higuchi, Korsmeyer, and Hixson, were utilized to investigate the release mechanism. According to the medication kinetics results, the Korsmeyer model, with a release exponent of 0.45 ˂ n ˂ 0.89 at pH 7.4 and 9.4, adhered to the non-Fick's rule of diffusion mechanism in the release profile. The correlation coefficients acquired from the Korsmeyer and Higuchi models indicate that the release mechanism involved diffusion and dissolution characteristics in all instances.

This research investigated the hydrothermal synthesis of NiO nanoparticles (NPs) to produce polymer nanocomposite photoresists. Initially, three hydrothermal synthesis methods for NiO NPs involving thermal heating of the precursor solution in a water bath, a convection oven, and a microwave oven (MW) were compared. Subsequently, the focus shifted to optimizing the MW-assisted synthesis parameters due to its efficiency and rapidity compared to the other methods. Two nickel salt precursors: Nickel Acetate Tetrahydrate and Nickel Nitrate Hexahydrate were examined. All NPs were analyze in terms of their morphology, structural characteristics, and purity. The most promising NiO NPs were then incorporated as nanofillers into two types of photoresists, a positive and a negative tone, yielding encouraging results as the lithographic properties of the resulting polymeric materials were maintained.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 12","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/slct.202405657","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
