Within the clinical trial EORTC 11001, patients were infused with (11)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.

Abstract
Within the clinical trial EORTC 11001, patients were infused with (11)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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
