Abstract

New series of Ag(I) and Cu(II) complexes with general formulas of Ag(AAT)(H2O)]NO3·H2O and Cu(AAT)(H2O)3]Cl2·H2O from 6-((5-chloro-2-hydroxyphenyl)diazenyl)-5-methylpyrimidine-2,4(1H,3H)-dione (AAT) were synthesized. By using FTIR, UV-vis, MS, and 1H-NMR, their molecular structural and binding properties were confirmed, which indicated that the AAT ligand acts as a neutral tridentate O, N, and N, forming tetrahedral geometry with Ag-AAT and distorted octahedral with Cu-AAT. Additionally, C.H.N analysis, magnetic susceptibility, molar conductivity, and thermal analysis were used to identify the synthesized compounds' stability and molecular formula and explore their physical and chemical properties. XRD and AFM were also examined, where the ligand and Cu(II) complex exhibited nanoscale properties. The biological potential of these compounds was also investigated by testing their antioxidant activity. Furthermore, the Cu(II) complex was investigated for its effects on liver function and histological abnormalities in male albino rats. The enzymatic activities of liver markers such as glutamic-oxaloacetic transaminase, glutamic-pyruvate transaminase, and alkaline phosphatase were measured to determine the hepatoprotective properties. Histological investigations of liver tissues revealed further evidence for the biological effects of the copper compound. These results revealed the potential applications of Ag(I) and Cu(II) complexes derived from the thymine-azo ligand.

Abstract

This article focuses on the synthesis of three Schiff base ligands derived from 2-hydroxybenzaldehyde (B: BBr, BOCH3, BNO2) and three azo dye ligands derived from naphthol (A: ABr, AOCH3, ANO2), followed by the preparation of copper(II) complexes with these six ligands in a 1:2 (metal:ligand) ratio. The ligands and complexes were characterized by using 1H-NMR, 13C-NMR, FTIR, UV-vis, and ESI-MS. Thermogravimetric and differential thermal analyses of the copper complexes indicated the absence of water molecules in the crystalline coordination, demonstrating high thermal stability. The findings confirmed the formation of square-planar copper complexes. The biological activity of the complexes was evaluated on breast cancer and healthy cells using the MTT assay at different concentrations. The IC50 analysis showed that CuABr, CuBBr, and CuAOCH3 had a significantly more substantial cytotoxic effect on cancer cells than on healthy cells. CuBOCH3 and CuBNO2 also exhibited notable selectivity toward cancer cells, whereas CuANO2 was more toxic to normal cells. These findings highlight the potential of CuABr, CuBBr, and CuAOCH3 as promising candidates for further development in targeted breast cancer therapy.

Abstract

Water pollution from heavy metal contamination is a global issue; finding low-cost and sustainable solutions is challenging. Among various methods, biomass adsorption is a practical approach for treating heavy metal contamination in agricultural water. This study explored the use of betel nut peel as a biosorbent to remove Mg(II), Ca(II), and Fe(III) ions from agricultural water. The adsorbent contained active groups like −OH, C=O, and C=C, indicating cellulose, lignin, and hemicellulose compounds. Mature betel nut peels showed higher adsorption capacities than immature ones due to their larger surface area and more active sites. The optimal adsorption occurred at an initial adsorbate concentration of 100 mg L−1 for 1 h, with 5 mg of biosorbent. The biosorbent followed the Langmuir isotherm and a pseudo-second-order kinetic model (R2 = 0.99), indicating chemisorption. When applied to agricultural water from South Sumatra, the biosorbent removed up to 90% of Fe(III) ions. These findings suggest that betel nut peel powder has strong potential as a biosorbent for heavy metals, with promising applications in water treatment and environmental remediation. It also shows potential as a biofertilizer, particularly for soils rich in Fe(III).

Abstract

This research aims to investigate the nanocomposite effectiveness from CuO:ZnO-NPs at a 1:1 ratio in water-polluting heavy metals adsorption from aqueous solutions, since these heavy metals adversely affect living organisms, including cadmium and iron. The research also examines the effectiveness of heavy metal removal when influenced by parameters like pH, adsorption dose, contact duration, initial concentration, and temperature. The maximum adsorption efficiency of heavy metals reached 86.7% for Cd(II) and 84.9% for Fe(II) at 25 °C when solution conditions totaled 10 mg/L of heavy metals alongside a pH setting of 6 using 0.09 g of sorbent. The structural and physical properties of the sorbent were analyzed by atomic and FTIR, along with FE-SEM, BET, XRD, and EDX systems. This study aimed to find an economical approach for heavy metal-infused water purification and analyze water quality changes to prove the feasibility of treating these pollutants using sorbent surfaces.

Abstract

A chitosan-zinc oxide (ZnO)/poly(ethylene glycol) (PEG)/pomegranate peel extract (PE) based hydrogel has been developed as a potential material to accelerate the wound healing process by controlling the drug release mechanism. ZnO nanoparticles with an average size of about 95 nm were synthesized using the coprecipitation method and then combined into chitosan/PEG composites to improve the antimicrobial properties of the hydrogels. Characterization of the hydrogels included analysis of size, morphology, elemental composition, microstructure, swelling behavior, antibacterial activity, and wound healing effectiveness. The results of the in vitro study indicated that the antibacterial activity of PE-containing hydrogel against Escherichia coli and Staphylococcus aureus decreased due to the chelation effect caused by PE addition. However, in vivo tests for 10 d showed that the PE-containing hydrogel had better wound healing ability than commercial betadine. In addition, the developed hydrogel showed high biocompatibility with excellent antibacterial activity. This study confirmed that chitosan/PEG/ZnO nanoparticle hydrogel has the potential as wound dressing materials with sustained drug release and optimal healing effectiveness.
