Description

Iomazenil, also known as iomazenil (123i) or (123i)iomazenil, belongs to the class of organic compounds known as imidazo[1,5-a][1,4]benzodiazepines. Imidazo[1,5-a][1,4]benzodiazepines are compounds containing an imidazole ring and a 1,4-benzodiazepine ring system, both sharing one nitrogen atom. Iomazenil is a strong basic compound (based on its pKa). The compound was introduced in 1989 by pharmaceutical company Hoffmann-La Roche as an Iodine-123-labelled SPECT tracer for imaging benzodiazepine receptors (GABAA receptors) in the brain. The effect of iomazenil of reducing levels of GABA in the brain was used by researchers to exacerbate symptoms in patients with schizophrenia in a laboratory study, supporting the theory that a GABA deficiency underlies that disease. Iomazenil is an analogue of flumazenil (Ro15-1788).123I-labelled iomazenil can be used to image epileptic seizure foci as an alternative to 18F-fludeoxyglucose PET imaging. Researcher Deepak D'Souza and colleagues at Yale University and Veterans Affairs Connecticut Healthcare System are testing iomazenil as a potential treatment for drunkenness due to its ability to bind alcohol receptors in the brain. This compound has been identified in human blood as reported by (PMID: 31557052 ). Iomazenil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Iomazenil 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.
