Studying Adsorption and Cellular Toxicity of Boron Nitride Nanostructure versus Melphalan Anti-ovarian Cancer Drug.

BACKGROUND

Inclusion of anticancer drugs into biocompatible nanoparticulate carriers decreases the general toxicity and improves the efficacy of clinical treatments due to the reduction of soluble circulating free drugs.

METHODS

In addition, removal of emerging drug contaminants from wastewaters is a necessity that should be seriously attended. Boron nitride (BN) is a choice in drug delivery because of its many surprising properties. Here, boron nitride nanoparticles are prepared, characterized by Fourier-transform infrared spectroscopy (FT-IR) and x-ray diffraction (XRD) and used in the delivery of melphalan anti-cancer drug.

RESULTS

Then, density functional theory (DFT) calculations are carried out to study the adsorption of this drug on the surface of pure boron nitride fullerene via familiar hybrid functionals B3LYP and B3PW91. In addition, the polarizable continuum model (PCM) calculations show that BN is stable in water.

CONCLUSION

Finally, the in vitro cellular toxicity and viability of BN nanoparticles was examined on ES-2 cancer cells. The inhibitory dose IC50 of the material confirmed acceptable cytotoxicity and nanoparticles affected the average growth of the ES-2 cancer cells.
