Abstrakt: The water-soluble fullerene derivative C60(OH)x was radiolabeled with 67GaCl3. The labeling yields were determined by radio-PLC. The effects of pH, reaction time, temperature and the amount of C60(OH)x on the labeling yields were studied. The stability of 67Ga-C60(OH)x was also examined. The results showed that the labeling yields could reach 97% under the best labeling conditions and the radiochemical purity of 67Ga-C60(OH)x solution kept at 37 °C remained at 88% after 212 hours. The biodistribution studies of 67Ga-C60(OH)x in mice showed a high localization of 67Ga-C60(OH)x in the bone marrow, bone, liver and spleen with slow clearance and a negligible accumulation in the blood. These data suggest that the water-soluble C60(OH)x, having the same properties as microcolloids, may be used as a carrier of drug system for lymphatic targeting. [ABSTRACT FROM AUTHOR]
