Abstract

The current study aimed at developing gold nanoparticles (AuNPs) using the aqueous extract of the medicinal plant Commiphora wightii. The phytosynthesized gold nanoparticles (Cw@AuNPs) were evaluated for their anticancer activity against MCF-7 breast cancer cell model. The formation of AuNPs by Commiphora wightii leaf extract was confirmed by UV�vis spectra where their surface plasmon resonance was found at 533 nm. Further characterization of Cw@AuNPs was done by transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) analysis, and fourier-transform infrared spectroscopy (FTIR) analysis. In vitro anticancer potential of thus obtained AuNPs was evaluated against MCF-7 and where the IC50 was found to be 66.11 μg/mL Further, apoptotic studies were carried out using ethidium bromide dual staining, DNA fragmentation, comet assay, and flow cytometry studies. Results revealed that Cw@AuNPs at higher concentration significantly increased the apoptotic cells when compared to control cells. Cell cycle analysis of MCF-7 cells confirmed the cell cycle arrest at G2/M phase. These results demonstrate that the biosynthesized Cw@AuNPs appear to be promising for therapeutical applications against breast cancer. © 2020 Elsevier Ltd
