Outline of Final Research Achievements

For improvement of the therapeutic efficacy, combinated medication of both sodium borocaptate (BSH) and p-boronophenylalanine (BPA) enriched with 10B, are applied in BNCT clinical studies at present, because this technology loaded of BSH and BPA simutaneously is expected to increase the accumulation of boron concentration in the tumors. Therefore, it is required to measure the individual boron concentration derived from the two different compounds respectively for the accurate dose estimation by neutron irradiation. In this study, an analytical method on the separation of the two boron compounds and individual concentration determination by using a liquid chromatography mass spectrometry (LC/MS) has been developed and the applicability to human plasma samples has been also studied. This analytical method is more practical and easier for individual born concentration determination from combination of BSH and BPA for BNCT. Furthermore, animal injection experiment is under research.
