| Outline of Final Research Achievements |
Boron neutron capture therapy (BNCT) is a form of tumor-cell selective particle irradiation using low-energy neutron irradiation of nonradioactive boron-10 (10B) to produce high-energy alpha particles (10B [n, alpha] 7Li). To develop practical materials utilizing 10B carriers, we designed and synthesized novel dodecaboranethiol (BSH)-containing kojic acid (KA-BSH). In the present study, we evaluated the effects of this novel 10B carrier on cytotoxicity, 10B concentrations in F98 rat glioma cells, and micro-distribution of KA-BSH in vitro. Furthermore, biodistribution studies were performed in a rat brain tumor model. Based on these results, neutron irradiation was evaluated at the Kyoto University Research Reactor Institute with KA-BSH. Based on these findings, KA-BSH is a promising new B compound for BNCT of brain tumors.
