Abstract:
Nanoparticles are attracting attention for their potential therapeutic applications, particularly in cancer therapy, underscoring their importance in medicine. Cadmium sulfide nanoparticles, known for their robust catalytic and optical properties, are classified as chalcogenides and show promise for cancer diagnosis and treatment. Neuroblastoma, a common solid tumor in childhood, poses a significant health threat with different outcomes depending on its biological subtype. This study evaluated the antiproliferative effects of cadmium sulfide nanoparticles on the SY-SH5Y cell line. Walnut shell extract and Na2S were used to facilitate the synthesis of cadmium sulfide nanoparticles by green synthesis. Characterization of the synthesized cadmium sulfide nanoparticles was performed by Fourier transform infrared spectroscopy, scanning electron microscopy, and x-ray diffraction analyses. The SH-SY5Y cell line was cultured in a standard cell culture medium and then exposed to different cadmium sulfide nanoparticles (10-25-50-75-100 µg/mL) for 24 hours. Cell viability, oxidant, and antioxidant levels were then assessed using a 3-(4,5-dimetiltiyazol-2-il)-2,5-difeniltetrazolyum bromür, total antioxidant, and total oxidant assays. The data showed that applying 100 μg/mL cadmium sulfide nanoparticles resulted in a significant decrease in cancer cell viability of up to 40.96 % (p<0.05). The cadmium sulfide nanoparticles had a dose-dependent effect on the SH-SY5Y cell line. Furthermore, cadmium sulfide nanoparticles increased oxidative activity in neuroblastoma cells, which was consistent with the results of the 3-(4,5-dimetiltiyazol-2-il)-2,5-difeniltetrazolyum bromür assay. In conclusion, cadmium sulfide nanoparticles exhibited potent activity against the neuroblastoma cell. This study highlights the antiproliferative efficacy of green-synthesized cadmium sulfide nanoparticles with walnut shell extract on relevant cancer cell lines.
