Metallofullerols and their applications for preparation of medicine for inhibition of tumor growth

A tumor-inhibiting composition, comprising:

• metallofullerol nanoparticles for treating a tumor;
• wherein
• the metallofullerol nanoparticles can be presented by a general formula
• [M@C2m(OH)x]n
• wherein M is a rare earth metal atom Gd or La,
• m has a numerical value of 41 or 30,
• x has a numerical value between 10 and 50,
• n has a numerical value between 1 and 200,
• with the proviso that when M is Gd and when m is 41, x cannot be 40,
• C2m indicates a fullerene selected from C82 or C60, and
• M@ indicates that the metal atom is incorporated inside the fullerene, and the composition is adaptable to treat a tumor, wherein the tumor is one member selected from the group consisting of lung cancer, liver cancer and breast cancer.

A method of treating a tumor with metallofullerol nanoparticles, comprising the steps of:

• preparing a tumor-inhibiting composition comprising metollofullerol nanoparticles;
• preparing a suitable dosage form of the tumor-inhibiting composition;
• and
• treating a tumor with the tumor-inhibiting composition at a suitable concentration, the tumor is one member selected from the group consisting of lung cancer, liver cancer and breast cancer,
• wherein the metallofullerol nanoparticles can be presented by a general formula
• [M@C2m(OH)x]n
• wherein M is a rare earth metal atom Gd or La,
• m has a numerical value of 41 or 30,
• x has a numerical value between 10 and 50,
• n has a numerical value between 1 and 200,
• C2m indicates a fullerene selected from C82 or C60, and
• M@ indicates that the metal atom is incorporated inside the fullerene.
