The synthesis of triorganotin(IV) ciprofloxacin dithiocarbamates of general formula R₃SnCip^dtc (R = Ph(1), Cy(2), ^<i>n</i>Bu(3), and Me(4)) and chloro-diorganotin(IV) ciprofloxacin dithiocarbamates R₂SnClCip^dtc (R = Ph(5), ^<i>n</i>Bu(6), and ^<i>t</i>Bu(7)) was carried out. To understand the chemical properties and the biological activity, a structural and electron density study was carried out by DFT approximation, and a docking analysis was performed to explain the antibacterial activity of the compounds. The results show that some of the compounds bind as ciprofloxacin and others bind differently, which helps to explain the MIC values obtained in comparison with the drug reference. The compounds were characterized by elemental analysis, IR, TGA, MS (FAB⁺), and ¹H, ¹⁹F, ¹³C, and ¹¹⁹Sn NMR spectroscopy. The solid-state IR data suggest that the tin atom is coordinated to the ligand in the bidentate coordination mode, and in solution, the ¹¹⁹Sn NMR is consistent with tetracoordination for <b>2</b>–<b>4</b> and pentacoordination for <b>1</b> and <b>5</b>–<b>7</b>. The molecular ion [M]⁺ of all compounds, <b>1</b>–<b>7</b>, was detected (FAB⁺). In compounds <b>1</b>–<b>7</b>, the Sn(IV) atom binds exclusively to the dithiocarbamate sulfurs, leaving the carboxylic acid oxygens intact. Antibacterial assays showed that all compounds except three were active in ATCC and clinically isolated strains. It is known that normally, the compounds containing triorganotin fragments typically exhibit higher antibacterial activity compared to those containing diorganotin. However, in the case of the compounds reported in this study, the antibacterial effect is contrary to this expectation. The presence of chlorine, instead of a second ciprofloxacin fragment, significantly increases the antibacterial efficiency.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Antibiotics, unlike many other pollutants, are designed to be stable and effective in the human body. However, it is essential to note that this advantageous characteristic can contribute to their prolonged existence and resistance to environmental breakdown. ZIF-67 and BaTi_0.85Zr_0.15O₃ nanomaterials are used in this investigation. A double Z-scheme nano-heterojunction BaTi_0.85Zr_0.15O₃/ZIF-67 (BTZ/ZIF-67) nanocomposite was designed for the improvement of photocatalytic degradation efficiency of tetracycline (TC). Material synthesis was carried out by the one-step coprecipitation method. Using scanning electron microscopy revealed the morphology of the nanophotocatalyst and the formation of heterojunctions on the nanocomposite. Under light irradiation, the nanocomposite with a mass ratio of (30%wt) of BTZ/ZIF-67 showed the best photodegradation efficiency. The best results were obtained at 0.8 g L⁻¹ of the catalyst, C_TC: 30 mg L⁻¹, a pH of 5, and 180 min of illumination. Several scavenging agents were studied for their effects on TC photodegradation, and it was determined that photogenerated electrons, superoxide radicals, OH radicals, and photogenerated holes play an important role. Accordingly, the Z-scheme mechanism was proposed to illustrate the charge carriers' transfer during the TC photodegradation process. According to the kinetic study, the photodegradation of TC molecules had an apparent rate constant of 0.0116 min⁻¹, corresponding to a t_1/2 value of 59.7 min. A COD has been conducted to determine the details of TC's mineralization. The Hinshelwood model applied to COD results for photodegraded TC showed that TC mineralization occurs at a rate constant of 0.020 min⁻¹, equivalent to 34.6 min in t_1/2.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a person may have some joint deterioration, inflammation is often not one of the first symptoms of osteoarthritis. Nonsteroidal anti-inflammatory drugs comprise the vast bulk of pharmaceuticals used in medicine. Even while these drugs remove the pain from the tissue, they do not deal with the condition's fundamental cause. Recently, copper nanoparticles (CuNPs) have been used in the composition of several pharmaceuticals and dietary supplements. In this study, we used CuNPs and an aqueous extract of <i>Lycium barbarum</i> leaves to develop a novel therapeutic drug for osteoarthritis. CuNPs were described using FT-IR, FE-SEM, TEM, UV–Vis, XRD, and EDX. The antiosteoarthritic potential was evaluated in vivo using complete Freund adjuvant (CFA), turpentine oil, and formaldehyde models at 80- and 240-μg/kg dosages. The development of CuNPs was illustrated by the distinct peak in the UV–Vis spectrum at 297 nm, and the CuNPs were spherical and ranged in size from 10 to 40 nm in the FE-SEM and TEM pictures. The results showed significant RBC membrane stability and concentration-dependent prevention of albumin denaturation, with the best results occurring at 240 μg/mL. The FT-IR measurement revealed that many antioxidant chemicals with related linkages created ideal conditions for copper reduction in the CuNPs. Similarly, nanoparticles showed a dose-dependent antiosteoarthritic activity, peaking at 240 μg/mL in models of formaldehyde and turpentine oil. Additionally, CuNPs changed hematological parameters, enhanced rheumatoid factor, and improved histological changes.

In this study, we synthesized a two-dimensional [Co (tib)(mpda)(H₂O)₂]·H₂O (Co-MOF) (tib = 1,3,5-tris(1-imidazolyl)benzene, H₂mpda = 1,3-phenylenediacetic acid) using a hydrothermal method.
