In this work [Zn(CH₃COO)(cur)(bpy)].CH₃OH·2H₂O (<strong>1</strong>), (cur = curcuminate, derived from curcumin, bpy = 2,2′-bipyridine) has been synthesized as an antibacterial inorganic coordination complex by using three different techniques, sonochemical reactions (<strong>1S</strong>), mechanochemical reactions (<strong>1M</strong>), and crystallization (<strong>1C</strong>). These methods were employed to obtain various morphologies and gradual release profiles, with the sonochemical and mechanochemical methods being used for the first time in the synthesis of this compound. To ensure the successful synthesis of the samples, FT-IR spectroscopy, PXRD, BET, SEM, and TGA analysis techniques were used. The results indicated that the samples were synthesized with the correct structure and obtained in nanoscale (<strong>1M</strong>), microscale (<strong>1C</strong>) and mixture of both nanoscale and microscale particles (<strong>1S</strong>). Then the rate of H₂O₂-sensitive release of curcumin and zinc ions as antibacterial agents from <strong>1</strong> was studied by UV–Vis and ICP-OES methods respectively by monitoring the concentration of released agents for about 120 h (5 days), in two phosphate-buffered solutions (PBS) with different hydrogen peroxide concentration as a simulated normal and infected cell tissues. Compound <strong>1</strong> demonstrated prolonged and gradual release of curcumin and zinc ions. Finally, <em>S. aureus</em> and <em>E. coli</em> bacteria as representatives of Gram-positive and Gram-negative bacteria, respectively, were used to study the antibacterial activity of the samples by the agar well diffusion and MIC/MBC method. Also, the time-kill kinetics of bacteria by samples investigated. All antibacterial analyses demonstrated significant and potent antibacterial activity of compound <strong>1</strong>. The high antibacterial efficiency of <strong>1</strong>, especially <strong>1C</strong>, is clearly demonstrated when compared to previous studies. It is possible to prevent the creation of antibacterial resistance as well as numerous environmental pollutions by using such compounds with the gradual release agents.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"171 ","pages":"Article 113599"},"PeriodicalIF":4.4,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142743528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nature of the interactions has been thoroughly investigated by the HOMO/LUMO energy gap, global reactivity descriptors, Mulliken charge distribution, molecular electrostatic potential (MEP) map, adsorption energy, and natural bond orbital (NBO) analysis. The reactivity of the two dyes was compared based on the LUMO and HOMO energy levels. It was found that SF⁺ with a LUMO value of −0.991 eV and lower energy gap of 1.184 eV exhibits an electrophilic characteristic and high ability to be strongly adsorbed on the MI₂. However, AB⁻ exhibits a higher energy gap of 5.854 eV, indicating its lower reactivity compared to SF⁺. Mulliken charge distribution of the dyes and their MEP map also showed strongly negative and strongly positive sites. Subsequently, the stabilizing interactions of hyper-conjugation and charge delocalization have been evaluated. In addition, the MD simulation was employed to elucidate the mechanism of the dye’s adsorption on the adsorbent surfaces.
