Novel, substituted benzamides in radioiodinated form are useful in radiopharmaceutical compositions in nuclear medicine as imaging agents to detect, visualize, and analyze the distribution and function of the dopamine D2 receptor in the mammalian brain. These compounds have a specific combination of lipophilicity and dopamine D2 receptor affinity required to attain a required image contrast. The iodinated benzamides identified by the above discovery can be made by reacting a trialkyltin substituted benzamide with an acid in the presence of radioactive iodine which, in turn, is generated by in situ oxidation of an appropriate iodide nuclide salt.

Radioiodinated benzamines and method of their use as radioimaging

Novel, substituted benzamides in radioiodinated form are useful in radiopharmaceutical compositions in nuclear medicine as imaging agents to detect, visualize, and analyze the distribution and function of the dopamine D-2 receptor in the mammalian brain. The substituted benzamides and their racemic mixtures or their optically resolved enantiomers can be made by reacting a trialyltin substituted benzamide with an acid in the presence of radioactive iodine, generated by in situ oxidation of an appropriate iodide nuclide salt.
