“…233 Imaging the distribution of the boron-containing vehicle has been addressed by F-18 labelling for PET, 234 or by imaging gamma rays emitted during neutron irradiation. 235 Although borocaptate has specificity for glioblastoma cells, 236 a number of boron-containing conjugates (mostly incorporating carboranyl or related clusters) have been synthesised to support novel targeting strategies. They include porphyrin and metalloporphyrin derivatives, 205,230,237 antisense oligonucleotides, 238 nucleosides, 239 glycosides, 240 amino acids, 241242 polyamines, 243 somatostatin analogues, 244 and ligands for benzodiazepine receptor.…”
