摘要

Within the clinical trial EORTC 11001, patients were infused with (10)B-enriched borono-phenylalanine-fructose complex (BPA-fr), or borocaptate sodium (BSH) solutions, which are used as boron carriers for boron neutron capture therapy. Urine samples were periodically collected and analyzed by (10)B NMR spectroscopy. The results revealed time-dependent metabolic changes of the administered compounds. BPA-fr dissociated to the constituents BPA and fructose, and the borate group was partly cleaved from BPA. BSH was partly aggregated to a dimer form, BSSB. These observations were previously reported for cultured cells and animal models, and are confirmed here in human cancer patients.
