Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/12605353

[123I]Iomazenil ([123I] IMZ) is a ligand displaying high affinity for central-type benzodiazepine receptors. It is a useful marker of neuronal viability. [123I]IMZ has been successfully used as a probe for single photon emission computed tomography (SPECT) in numerous clinical studies of diseases and also itcan be used to image epileptic seizure foci. 123I-iomazenil is rapidly metabolized and more than 90% of the administrated radioactivity was excreted within the first 24 hr. Dominant metabolites were acid metabolite (R-COOH), glucuronide of the acid (R-COOH-Glc) and free iodide (I-). Metabolites of 123I-iomazenil do not cross the blood-brain barrier. [123I]IMZ is readily available commercially.

CNS Activity

Curator's Comment: At 3 hr after injection, more than 97% of the radioactivity in rat brain was found in the form of the parent compound, 123I-iomazenil
