Formulation of a novel anti-human bone tumor supplement by silver nanoparticles green-synthesized using Nigella sativa leaf aqueous extract

Abstract

IntroductionIn the present research, we formulated a modern chemotherapeutic drug by silver nanoparticles (AgNPs) containing Nigella sativa aqueous extract for the treatment of bone tumor.Material and methodsCharacterization of AgNPs was done by UV–Visible Spectroscopy (UV-Vis), Fourier Transformed Infrared Spectroscopy (FT‐IR), Transmission Electron Microscopy (TEM), and Field Emission Scanning Electron Microscopy (FE‐SEM). For investigating the antioxidant properties of AgNO3, N. sativa, and AgNPs, the DPPH test was used in the presence of butylated hydroxytoluene as the positive control. To survey the cytotoxicity and anti-bone tumor effects of AgNO3, N. sativa, and AgNPs, MTT assay was used on the human bone Ewing’s sarcoma (CADO-ES1 and MHH-ES1), human bone osteosarcoma (HOS and MG-63), and human bone chondrosarcoma (SW-1353 and CH-3573) cell lines.ResultsDPPH test revealed similar antioxidant potentials for N. sativa, AgNPs, and butylated hydroxytoluene. Silver nanoparticles had very low cell viability and anti-bone tumor properties dose-dependently against CADO-ES1, MHH-ES1, HOS, MG-63, SW-1353, and CH-3573 cell lines without any cytotoxicity on the normal cell line. The best result of anti-bone tumor properties of AgNPs against the above cell lines was seen in the case of the MG-63 cell line.ConclusionsAccording to the above findings, the silver nanoparticles containing N. sativa aqueous extract can be administrated in humans for the treatment of several types of bone tumors.
