Combining polyphenols with other bioactive compounds within nanoparticles can create synergistic effects, enhancing their overall therapeutic potential. In this work, we present a new polyethylene glycol (PEG) capping ligand modified with caffeic acid (CA), HS-PEG-CA and two types of gold nanoparticles: (i) coated with a PEG-thiol derivative functionalized with CA (HS-PEG-CA) (homofuncionalized NP) and (ii) HS-PEG-CA cationic carbosilane dendrons with antibacterial properties (heterofuncionalized NP). The antioxidant capacity of the CA, in three systems, has been studied by different techniques such as FRAP, DDPH and cyclic voltammetry, demonstrating that it is preserved when it is supported on the NP and increases when it is part of the PEG ligand.

Quinoline complexes, in particular, have emerged as significant entities, demonstrating a wide array of medicinal properties, including antibacterial, antifungal, antiviral, anticancer, anthelmintic, anti-HIV, antioxidant, antituberculosis, and antimalarial activities. In addition, they showed promise in photodynamic and neurological studies, along with strong DNA-binding capabilities. In recent years (2010-2023), substantial progress has been made in understanding quinoline complexes. Key aspects such as the lipophilicity, of metal complexes, enzymatic drug degradation factors influencing inhibition, drug performance, disruption of target cell growth, and their impact on DNA have been thoroughly investigated. Researchers have employed advanced methodologies including fluorescent imaging, determination of MIC and IC<sub>50</sub> values, hydrodynamic and spectrophotometric techniques, in silico and in vitro studies, and cytotoxicity assessments using the MTT method, to significantly enhance our understanding of these complexes. Recent findings indicated that the interaction of quinoline complexes with viral proteins and their ability to disrupt enzyme-viral DNA relationships have made them powerful therapeutic agents for severe diseases including cancer, AIDS, and coronaviruses, as well as various neurological and microbial infections. It is anticipated that these explorations will lead to effective advancements in therapeutic strategies within modern medicine.</p>","PeriodicalId":8914,"journal":{"name":"Bioinorganic Chemistry and Applications","volume":"2025 ","pages":"3133615"},"PeriodicalIF":4.7,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11835480/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, the decavanadate compounds represent promising tools to design efficient therapeutic agents. In our study, we synthesized a dimagnesium disodium decavanadate icosahydrate compound (Mg<sub>2</sub>Na<sub>2</sub>V<sub>10</sub>O<sub>28</sub>·20H<sub>2</sub>O) and investigated its structure stability as well as its antimelanoma effects. Results showed that the Mg<sub>2</sub>Na<sub>2</sub>V<sub>10</sub>O<sub>28</sub>·20H<sub>2</sub>O compound is structured in a monoclinic system with the space group C2/c, stabilized by oxygen vertices, hydrogen bonds, and van der Waals interactions. Interestingly, we found that this newly synthesized compound reduced the viability of human (IGR39, IGR37, and SKMEL28) and murine (B16-F10) melanoma cells in a dose-dependent manner. The IC<sub>50</sub> values ranged from 7.3 to 18 μM after 24 h and decreased to 1.4 μM after 72 h of treatment. Notably, this effect was more important than that of cisplatin (IC<sub>50</sub> = 3 μM after 72 h of treatment), a chemotherapeutic agent, commonly used in the treatment of malignant melanoma. Furthermore, the cytotoxicity of the decavanadate compound was relatively weak on normal human keratinocytes (HaCaT), with a light effect (IC<sub>50</sub> >> 70 μM) observed after 24 h of treatment. Thus, the Mg<sub>2</sub>Na<sub>2</sub>V<sub>10</sub>O<sub>28</sub>·20H<sub>2</sub>O compound displayed an advantage over cisplatin, which was reported to be much more aggressive to the keratinocyte cell line (IC<sub>50</sub> = 23.9 μM). Moreover, it inhibited dose-dependently the adhesion of IGR39 cells to collagen (IC<sub>50</sub> = 2.67 μM) and fibronectin, as well as their migration with an IC<sub>50</sub> value of 2.23 μM. More interestingly, its in vivo administration to B16-F10 allografted mice, at the nontoxic dose of 50 μg (2.5 mg/kg), prevented and suppressed by 70% the tumor growth, compared to the nontreated mice. Moreover, this compound has also allowed a recovery against inflammation induced in mice by a mixture of DMBA and croton oil. Thus, all our results showed the potential of the Mg<sub>2</sub>Na<sub>2</sub>V<sub>10</sub>O<sub>28</sub>·20H<sub>2</sub>O compound to prevent and efficiently treat the growth and metastasis of melanoma.</p>","PeriodicalId":8914,"journal":{"name":"Bioinorganic Chemistry and Applications","volume":"2025 ","pages":"6680022"},"PeriodicalIF":4.7,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11742080/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142999352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
