New anti-cancer therapy with boron neutron capture therapy (BNCT) is based on the nuclear reaction of boron-10 with neutron irradiation. The median survival of BNCT patients with glioblastoma was almost twice as long as those receiving standard therapy in a Japanese BNCT clinical trial. In this ...detailed
The successful treatment of cancer by boron neutron-capture therapy (BNCT) requires the selective delivery of relatively high concentration of 10B compounds to malignant tumor tissue. This study focuses on a new tumor-targeting drug delivery system for BNCT that uses small (less than 200 nm in d...detailed
A high-performance liquid chromatographic (HPLC) method was developed for the determination of disodium mercaptoundecahydrododecaborate (BSH) in biological fluids. Monobromobimane was used as a precolumn derivatizing agent. A stable derivative was obtained. The derivative was separated on a C18 ...detailed
Mercaptoundecahydrododecaborate (BSH) is an important agent for the boron neutron-capture therapy (BNCT). A sensitive high-performance liquid chromatographic (HPLC) method was developed for measuring BSH concentrations in rat tissues. Various tissue samples containing the drug were homogenized i...detailed
A simple and rapid method for the quantitative measurement of mercaptoundecahydrododecarborate (BSH), (which presently is one of the most useful agents for Boron Neutron Capture Therapy) in human plasma was developed by using Fourier transform infrared spectroscopy. Different spacer thicknesses ...detailed
A series of mercaptoundecahydrododecaborate (B12H11SH2−, BSH) bearing mono- and dicarboxyalkyl derivatives was prepared, characterized, and their reactivity towards amidation and esterification in DMF was evaluated. Symmetrical alkylation of BSH was achieved by treatment with primary haloalkyl c...detailed
A simple, specific and accurate method for the quantitation of sodium mercaptoundecahydrododecaborate, which is a very hygroscopic agent for boron neutron-capture therapy, was developed by using capillary isotachophoresis with sodium p-toluenesulphonate as an internal standard. Compound 1a was s...detailed
The interaction of mercaptoundecahydrododecaborate (B12H11SH2−, BSH) with phosphatidylcholine was investigated in this study in order to illuminate possible uptake mechanisms of BSH in tumor cells. BSH has been used clinically in Japan as a boron containing agent in patients with malignant brain...detailed
