The amino acid melanin precursor analogue, p-boronophenylalanine (BPA) has previously been tested in melanoma bearing animals1,2 and used in clinical trials of BNCT.3,4 In the case of melanoma, it is a rational biochemical approach to load the tumour with this precursor analogue, since melanin is synthesised from the amino acid phenylalanine. However, it has been found that BPA can selectively accumulate in tumours other than melanoma; for example, in a murine mammary adenocarcinoma, in a rat glioma, and in a xenografted human glioma.4 The use of BPA has therefore been proposed for BNCT of high grade brain cancer, since it can penetrate the blood brain barrier (BBB), so that it is possible to load the required concentration of boron into the tumour cells. Pharmacokinetic studies of BPA-fructose have been performed in human patients with melanoma or glioma and uptake into cerebral tumours was found to be adequate for BNCT.5,6
