Metabolite Identification
Common NameIobenguane
DescriptionIobenguane belongs to the class of organic compounds known as iodobenzenes. These are aromatic compounds containing one or more iodine atoms attached to a benzene. Iodine 123 is a cyclotron-produced radionuclide that decays to Te 123 by electron capture. The radioisotope used can either be iodine-123 for imaging or iodine-131 for destruction of tissues that metabolize noradrenaline. Images are produced by a I123 MIBG scintigraphy. Iobenguane is a very strong basic compound (based on its pKa). AdreView is a diagnostic radiopharmaceutical which contains a small quantity of iobenguane that is not expected to produce a pharmacodynamic effect. Patients with renal insufficiency may experience increased radiation exposure and impaired imaging results. Less than 10% of the dose is metabolized into m-iodohippuric acid (MIHA). The most common adverse reactions, dizziness, rash, pruritis, flushing, headache, and injection site hemorrhage occurred in < 1.3% of patients. Structure of iobenguane is similar to noradrenaline so it can be taken up by adrenergic tissue in the adrenal medulla, liver, heart, and spleen. FDA approved on September 19, 2008. Oral, rabbit: LD50 = 3200 mg/kg;. This compound has been identified in human blood as reported by (PMID: 31557052 ). Iobenguane is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Iobenguane is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
