Abstract
Novel water-soluble fullerene–glycine derivatives were synthesized by means of simple organic chemistry. They are completely soluble in water, yielding a clear brown solution. The products were characterized by fourier transform infrared (FTIR), ultraviolet–visible spectroscopy (UV–Vis), 1H NMR, 13C NMR, thermogravimetric analyses (TGA), and scanning electron microscopy (SEM). The assembly behavior of water-soluble fullerene–glycine derivatives was investigated by SEM. The results show that the fullerene–glycine derivatives create morphology that is sphere-like. The cytotoxicity to cancer cell lines of the fullerene–glycine derivatives was evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) and flow cytometry. The results show that fullerene–glycine derivatives exhibit mortality and apoptosis of the cells which increased with the increase of fullerene–glycine derivative concentration. The cytotoxicity mechanism of fullerene–glycine derivatives was investigated for the first time.
Graphical Abstract
Novel water-soluble fullerene–glycine derivatives were synthesized by means of simple organic chemistry. The products were characterized by FTIR, UV–Vis, 1H NMR, 13C NMR, TGA, and SEM. The bioactivities of fullerene–glycine derivative materials have been tested, and the results show that compared with the fullerene complex, the fullerene–glycine derivative materials exhibit mortality and apoptosis of the cells which increased with the increase of fullerene–glycine derivative concentration. SEM images showed the macrostructure of fullerene–glycine derivative materials was spheres.
