| Outline of Final Research Achievements |
Boron neutron capture therapy (BNCT) is based on the capture reaction of thermal neutrons and nonradioactive 10B, which produces an α-particle and a lithium-7 nuclei ion with approximately 2.4 MeV. We developed the liposomes with high boron contents as efficient boron delivery vehicles for BNCT. We optimized DSBL contents in the liposome preparation and found that 10% DSBL liposome is stable in blood circulation. Furthermore, we succeeded in encapsulation of BSH into the vacant inner of the 10% DSBL liposomes, producing the liposomes with high boron contents. We examined boron biodistribution in the tumor-bearing mice by injection of BSH-encapsulating DSBL liposomes via the tail vein. High boron accumulation was observed in the tumor tissue 36 h after injection of the liposomes. Significant tumor growth suppression was observed in the boron-loaded mice after neutron irradiation.
