title: In vitro effects of boron-containing compounds upon glioblastoma cells.
abstract: Boron-neutron capture therapy (BNCT) is currently under investigation as a novel therapeutic modality for glioblastoma. This study was undertaken to determine whether boron-containing compounds 4-borono-2-fluoro-D,L-phenylalanine (FBPA) and FBPA-fructose have direct effects upon kinetics of A172, a glioblastoma cell line. Flow cytometry analyzed cell-cycle distribution and S-phase kinetics (bromo deoxyuridine [BUdR] incorporation). BUdR incorporation was increased during a 1-hr pulse after 24-hr or 72-hr exposure of cells to varying concentrations of FBPA or FBPA-fructose. Results suggest that boron-containing compounds may effect cell kinetics apart from neutron activation, and this effect should be further evaluated for potential impact upon tumor responsiveness to BNCT.
