Abstract
5-Fluorouracil (5-FU), a potent and widely used chemotherapeutic agent for breast cancer, faces limitations due to its cumulative dose-dependent cardiotoxicity. To address this challenge, we have developed a novel drug delivery system based on the environmentally friendly synthesis of magnetic iron oxide nanoparticles (Fe3O4 NPs). In this study, we successfully synthesized Fe3O4@GL-PEG-5-FU-NPs as an efficient nanocarrier for targeted drug delivery. These nanocomposites were comprehensively characterized to assess their morphology, composition, and chemical structure. Antibacterial studies conducted at concentrations ranging from 50 to 100 μg/mL demonstrated significant inhibition of bacterial growth, primarily attributed to the generation of reactive oxygen species (ROS). Additionally, an IC50 value of 25.12 μg/mL in human red blood cells highlighted the strong anti-inflammatory potential of the Fe3O4@GL-PEG-5-FU-NPs. These findings suggest their suitability as anti-inflammatory agents. Cytotoxicity assays further revealed that the nanocomposites exhibited dose-dependent anticancer activity against various human cancer cell lines, with particularly potent cytotoxicity against MCF-7 breast cancer cells (IC50 = 10.5 μg/mL). The multifunctionality of Fe3O4@GL-PEG-5-FU-NPs–encompassing antibacterial, anti-inflammatory, and anticancer effects presents a promising avenue for further research. Overall, this study enhances our understanding of nanoscale drug delivery systems and highlights the potential of nanotechnology in advancing pharmaceutical applications.
期刊介绍:
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
