Chitosan-silver nanoparticles containing Diosgenin (DGN-ChAgNPs) were synthesized and evaluated for their anticancer activity against breast cancer cells. The results showed promising inhibitory effects on cell proliferation, suggesting the potential of DGN-ChAgNPs as a treatment therapy for breast cancer.
The discovery of effective therapeutic approaches with minimum side effects and their tendency to completely eradicate the disease is the main challenge in the history of cancer treatment. Fenugreek (FGK) seeds are a rich source of phytochemicals, especially Diosgenin (DGN), which shows outstanding anticancer activities. In the present study, chitosan-silver nanoparticles (ChAgNPs) containing Diosgenin (DGN-ChAgNPs) were synthesized and evaluated for their anticancer activity against breast cancer cell line (MCF-7). For the physical character-ization, the hydrodynamic diameter and zeta potential of DGN-ChAgNPs were determined to be 160.4 +/- 12 nm and +37.19 +/- 5.02 mV, respectively. Transmission electron microscopy (TEM) showed that nanoparticles shape was mostly round with smooth edges. Moreover, DGN was efficiently entrapped in nanoformulation with good entrapment efficacy (EE) of similar to 88 +/- 4 %. The in vitro anti-proliferative activity of DGN-ChAgNPs was performed by sulforhodamine B (SRB) assay with promising inhibitory concentration of 6.902 +/-; 2.79 mu g/mL. DAPI staining, comet assay and flow cytometry were performed to validate the anticancer potential of DGN-ChAgNPs both qualitatively and quantitatively. The percentage of survival rate and tumor reduction weight was evaluated in vivo in different groups of mice. Cisplatin was used as a standard anticancer drug. The DGN-ChAgNPs (12.5 mg/kg) treated group revealed higher percentage of survival rate and tumor reduction weight as compared to pure DGN treated group. These findings suggest that DGN-ChAgNPs could be developed as potential treatment therapy for breast cancer.
