Tumor-directed radioisotope carriers

Nevertheless, pendant arm derivatives of [9]aneN3 and other polyaza-macrocycles have garnered great interest in recent years for their use in many different chemical applications such as catalysis [24-30], selective cation binding [30-32], surfactants [33, 34], mimicry of enzymes and siderophores [35-39], tumor-directed radioisotope carriers, and use in magnetic resonance imaging reagents [40],...
