| Outline of Final Research Achievements |
Because cancer is a leading cause of death in Japan, development of imaging technology for cancer diagnosis and drug delivery systems for cancer therapy are crucial. Dendrimers are synthetic macromolecules with highly controllable structures, which are potent multifunctional imaging agents and drug carriers. The detection of the sentinel lymph node (SLN), the first lymph node draining tumor cells, is important in cancer diagnosis and therapy. First, the optimal dendrimer structure for SLN imaging was investigated. Carboxyl-terminal dendrimers of greater than G4 were mostly located in the SLN. SLN detection was successfully performed by nuclear medicinal imaging and fluorescent imaging using these dendrimers. Finally, triply functional dendrimers with tumor targeting activities, antitumor effects and detectable probes were prepared.
