Özet

In the present research, metal–organic framework-5 (MOF-5) was synthesized and loaded with zerumbone (ZER@MOF-5), followed by the evaluation of its anticancer, antibacterial, antifungal, DNA-binding, and free radical scavenging potentials. The synthesized nanoparticles were characterized using X-ray diffraction, ultraviolet–visible spectroscopy, Fourier-transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and scanning electron microscopy. The in vitro anticancer activity of ZER@MOF-5 was studied in a human breast cancer cell line (MCF-7) using the CCK-8 assay. The interaction of ZER@MOF-5 with pBR322 plasmid DNA was assessed by gel electrophoresis. The antimicrobial effect of ZER@MOF-5 was examined in gram-positive and gram-negative bacterial strains and yeast strains using the microdilution method. The free radical scavenging activity was assessed using the DPPH assay. Cytotoxicity assay revealed a notable enhancement in the anticancer activity of zerumbone upon its encapsulation into MOF-5. The IC50 value for ZER@MOF-5 was found to be 57.33 µg/mL, which was lower than that of free zerumbone (IC50: 89.58 µg/mL). The results of the DNA-binding experiment indicate that ZER@MOF-5 can bind to target DNA and cause a conformational change in DNA. The results of the antibacterial activity experiment showed that the antibacterial ability of ZER@MOF-5 was limited compared to free zerumbone. The results of the DPPH assay demonstrated that the antioxidant activity of free zerumbone was higher than that of ZER@MOF-5. MOFs encapsulate compounds within their porous crystalline structure, which leads to prolonged circulation time compared to single ligands. Although the unique structure of MOFs may limit their antibacterial and antioxidant activity in the short term, it may increase therapeutic efficacy in the long term. However, to fully understand the long-term antibacterial and antioxidant effects of the ZER@MOF-5, further comprehensive in vitro and in vivo experiments are necessary. This finding indicates that the MOF-5 could potentially be an impressive carrier for the oral administration of zerumbone.
