Research Abstract |
The sonodynamically induced antitumor effect of fullerene derivatives such as pyrrolidine tris fullerenes (PTF) and polyhydroxy fullerenes (PF) was investigated. Both in vitro and in vivo antitumor effects were tested in combination with ultrasound at 2 MHz. The rate of ultrasonically induced damage on isolated sarcoma 180 cells in air-saturated suspension was enhanced by twice with80 〓M fullerene derivatives. This enhancement was significantly inhibited by histidine, which maysuggest it was mediated by ultrasonically induced oxidation. The coadministraion of 25 mg/kg fullerene derivatives followed by ultrasonic exposure at 2 MHz suppressed the growth of implanted colon 26 tomors at an intensity with which ultrasound alone showed only a slight antitumor effect.
