脳腫瘍モデルラットにおけるホウ素中性子捕捉治療用薬剤ホウ素化フェニルアラニン(BPA)のMALDI質量分析イメージングに関する検討
Boron neutron capture therapy (BNCT) is a cell-selective particle therapy for cancer using boron containing drugs. Boron compounds are accumulated in high concentration of tens ppm level of boron in target tumors to cause lethal damage to tumor tissue. We examined matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) to visualize the distribution of a typical BNCT drug, L-4-phenylalanine boronic acid (BPA) in a brain tumor model rat using a spiral orbit-type time of flight (SpiralTOF) mass spectrometer.
