The present study aims to develop a novel copper complex that inhibits the proteasome in skin squamous cell carcinoma. New molecules based on the copper complex were synthesized for the first time to assess their potential as proteasome inhibitors, specifically targeting squamous cell carcinoma induced by 7,12-dimethylbenz(a)anthracene (DMBA) in mouse models. Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), nuclear magnetic resonance (NMR), and energy dispersive X-ray analysis (EDX) were carried out to characterize this new copper complex. Notably, the presence of a papilloma (skin tumor) was confirmed by histopathological analysis. Subsequent investigation included the quantification of proteasome levels using a sandwich ELISA test, and the catalytic activity of the 20S proteasome was determined by measuring the fluorescence emitted after the cleavage of 7-amino-4-methylcoumarin (AMC). Hence, X-ray crystallography indicates that all Cu atoms are five-coordinated in a square-pyramidal configuration and biological activity of copper Schiff base complex, which exhibits high proteasome inhibitory activities with particular selectivity of <em>β</em>5 subunit. The pharmacokinetic properties (ADMET) of the copper complex named Cu(L1) showed encouraging results with very low toxicity, distribution, and absorption. Structure–activity relationship (SAR) information obtained from Cu(L1) demonstrated its selectivity and potent inhibition for <em>β</em>5 subunit. In this regard, this copper complex has emerged as a novel therapy for skin cancer.</div></div>","PeriodicalId":49970,"journal":{"name":"Journal of Trace Elements in Medicine and Biology","volume":"86 ","pages":"Article 127533"},"PeriodicalIF":3.6,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142314948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the literature about environmental factors affecting mineral composition in mushrooms is scarce and limited to the ambiguous impact of soil properties and region. In our study, we investigated the effects of tree stand characteristics (tree species and tree canopy cover), understory cover, and soil properties (pH and C/N ratio of the soil) on the concentration of minerals in six edible mushroom species: <em>Laccaria laccata</em>, <em>L. proxima</em>, <em>L. amethystina</em>, <em>Lepista nuda</em>, <em>Lycoperdon perlatum</em>, and <em>Calvatia excipuliformis</em>, collected on 20 plots covered by stands of different tree species composition and varying in the understory cover. We estimated the concentration of eight elements (Zn, Se, Mg, Mn, Cu, Co, Cr, Mo) using the ICP-MS (Inductively Coupled Plasma - Mass Spectrometry) technique and compared their concentration between the plots, using ordination and linear regression methods. Our research revealed that mushroom species identity, including its ecological role and phylogenetic affinity, had the greatest effect on the mineral composition of mushrooms. The effect of environmental factors depended also on the micronutrient identity. Some elements were not affected at all (Co, Cr), some only by soil reaction or C/N ratio (Mn, Mg, Cu), while others were influenced by both tree stand characteristics and soil properties (Se, Zn, Mo). This knowledge enables us to maximize the content of minerals in harvested mushrooms by collecting them in specific areas. For example, mushrooms, which are sources of Se and Zn, can be gathered in coniferous forests characterized by acid soils, low canopy cover, and minimal understory cover. This targeted collection approach can effectively increase the mineral content in harvested mushrooms, thereby enhancing their health benefits.</p></div>","PeriodicalId":49970,"journal":{"name":"Journal of Trace Elements in Medicine and Biology","volume":"86 ","pages":"Article 127534"},"PeriodicalIF":3.6,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0946672X24001548/pdfft?md5=2237eea8e979b4ad16e8a956cab4ba76&pid=1-s2.0-S0946672X24001548-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142272805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
