Abstract

Reaction yield optimization for the synthesis and the complexation of a boron neutron capture therapy agent (19)F-labelled, (10)B-enriched p-boronophenylalanine-fructose ((19)F-BPA-fr) complex was obtained. (1)H, (19)F, (13)C and (10)B magnetic resonance spectroscopy (MRS) of the (19)F-BPA-fr complex in aqueous and rat blood solution phantoms and its spatial distribution mapping using (19)F magnetic resonance imaging (MRI) results are reported. 7 T and 9.4 T magnetic fields were used to perform MRI and MRS respectively. Our in vitro results suggest that in vivo studies on (19)F-BPA through (19)F NMR will be feasible.
