User: I want to know more about the molecule with SMILES O=C([O-])CN(CCN(CC(=O)[O-])CC(=O)[O-])CCN(CC(=O)[O-])CC(=O)[O-].[99Tc+4].
Assistant: Sure, what is your question?
User: Please describe this drug.
Assistant: The answer is Technetium Tc-99m DTPA is a radiopharmaceutical core of chelating agent DTPA (diethylenetriaminepentaacetic acid) complexed with the gamma-emitting radionuclide technetium Tc 99m with radioimaging application. Tc-99m-DTPA has been utilized as a radiotracer, when conjugated to tissue specific molecules, in a wide variety of nuclear imaging studies, including brain, lung, and renal function studies.
