Abstract
This study aimed to design and synthesize a pH-controlled release nanocarrier, MIL-101(Fe), for load and targeted delivery of quercetin (Que), as a natural antioxidant, to MCF-7 cell breast cancer. Before and after Que loading, numerous analyses were directed to characterize the synthesized nanocomposite. High Que loading content (54.9 %) and its release behavior dependent on pH were observed through in vitro loading and release studies. The UV–vis analysis results indicated that MIL-101(Fe) exhibits a faster release rate at pH 5. The Que release profile was investigated for 9 days, and in this period (pH 5), 56.7 % of the total Que was released. To assess cell viability after treatment with Que, MIL-101(Fe), and Que@MIL-101(Fe), MTT assays were utilized to measure cytotoxicity on both MCF-7 breast cancer cells and MCF-10A normal cells for up to 48 h. The results demonstrated a stronger ability of Que@MIL-101(Fe) to inhibit MCF-7 cell growth while exhibiting significantly lower toxicity in MCF-10A cells, indicating selective cytotoxicity toward cancerous cells. The investigation of enzymatic and non-enzymatic antioxidants displayed an effective reduction in treated cells with Que@MIL-101(Fe). Molecular docking simulations were conducted against human liver CAT and SOD in order to verify the inhibitory effect of the Que. All obtained results have shown that this system can be a practical nanoplatform for successfully delivering Que to cancer cells and augmenting its anticancer effects while maintaining biocompatibility with normal cells, enhancing its therapeutic potential.
期刊介绍:
The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including:
• Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.)
• Chemical intermediates
• Molecules in excited states
• Biological molecules
• Polymers.
The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example:
• Infrared spectroscopy (mid, far, near)
• Raman spectroscopy and non-linear Raman methods (CARS, etc.)
• Electronic absorption spectroscopy
• Optical rotatory dispersion and circular dichroism
• Fluorescence and phosphorescence techniques
• Electron spectroscopies (PES, XPS), EXAFS, etc.
• Microwave spectroscopy
• Electron diffraction
• NMR and ESR spectroscopies
• Mössbauer spectroscopy
• X-ray crystallography
• Charge Density Analyses
• Computational Studies (supplementing experimental methods)
We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
