Outline of Final Research Achievements

In order to develop an effective analytical method to distinguish the 10B concentration from the different boron compounds of BSH and BPA applied in BNCT clinical trials, BSH and BPA were administrated to Wistar rats in this research. According to our previous report, the tendency of BSH and BPA in rat plasma is investigated for the single or combined administration used by a LC/MS analytical method. Furthermore, the dose of BSH and BPA were adjusted in different ratio to examine the pharmacokinetic properties of the two boron compounds. It is confirmed that total 10B concentration existed in rat plasma is related to the dose ratio of BSH and BPA.

Academic Significance and Societal Importance of the Research Achievements

2剤が併用されるBNCTの臨床において、実験データが極めて少ない状況の中、本研究はホウ素化合物を標的にして、異なる2種類のホウ素化合物を弁別した濃度測定法の確立、そして生体内における各々の薬物動態特性を把握した。これらの研究成果は2剤が併用されるBNCTの臨床治療効果の事後検証の精度向上に期待ができ、学術的な意義が大きい。
