| Abstract: | A novel fullerene-lysine derivative is synthesized by means of organic chemistry. It is soluble in polar solvents such as water, dimethyl sulfoxide and tetrahydrofuran et al. The product is characterized by FTIR, ^1 HNMR, TEM. TEM analysis shows that it presents an ideal spherical shape in water with an average particle diameter of about 30nm. The antitumour mechanism of the derivative is studied. The in vitro antitumour activity of the novel derivative is also tested and the result shows that the novel derivative exhibits better antitumour activity in vitro against bone tumour cells. The in vitro antitumour activity of the novel derivative is related to the derivative concentration, and the power of the light irradiation. |
