Synthesis and pharmacological characterization of 4-[125I]-N-(N-benzylpiperidin-4-yl)-4-iodobenzamide: a high affinity sigma receptor ligand for potential imaging of breast cancer.


The synthesis of [125I]-N-(N-benzylpiperidin-4-yl)-4-iodobenzamide (4-[125I]BP), a novel radiopharmaceutical that possesses high affinity for both sigma-1 and sigma-2 receptor subtypes, and its binding characteristics to MCF-7 breast cancer cells are described. To obtain high yields (with high specific activity) of radioiodinated ligand, (N-benzylpiperidin… (More)
