Background and Objective: Cancer is a complex interaction among multiple signalling pathways involving a variety of target molecules. Nanoparticles were used in cancer treatment because of their intrinsic anticancer properties. The use of plant extracts in the preparation of metallic nanoparticles as a convenient substitute has been proposed. This study assessed the cytotoxic, antioxidant and apoptotic effects of copper nanoparticles shelled with either turmeric or sumac biosynthesized as core-shell nanostructures on the liver tumour cell line (Huh-7). Materials and Methods: The nanostructures were synthesized by sonochemical method and characterization was done to confirm the successful synthesis within the nanoscale. Cytotoxicity of nanostructures was investigated on Huh-7 and normal kidney epithelial cell lines (VERO). Malondialdehyde, nitric oxide, reduced glutathione and superoxide dismutase were estimated in cell lysate to assess the antioxidant properties of nanostructures. Caspase-3 was also measured as an apoptotic marker. Results: Both nanostructures had low IC₅₀ on Huh-7 cells and a non-toxic effect on VERO cells. The cytotoxic effect was coupled with a significant increase in antioxidant activities and apoptotic efficiency compared to control. Conclusion: The findings summarized here support the utilization of biosynthesized copper with turmeric or sumac as core-shell nanostructures as a novel chemotherapeutic drug for cancer treatment that improves antioxidant effect that modulates the side effect of cytotoxicity. Also, it is obvious that copper nanostructure biosynthesized with turmeric has a more advanced effect than that of sumac.
