Description2'-(4-ethoxyphenyl)-5-(4-methylpiperazin-1-yl)-2,5'-bibenzimidazole, also known as hoe 33342 or bisbenzimide, belongs to the class of organic compounds known as phenylbenzimidazoles. Phenylbenzimidazoles are compounds containing a phenylbenzimidazole skeleton, which consists of a benzimidazole moiety where its imidazole ring is attached to a phenyl group. Based on a literature review very few articles have been published on 2'-(4-ethoxyphenyl)-5-(4-methylpiperazin-1-yl)-2,5'-bibenzimidazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Bisbenzimide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Bisbenzimide 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.
