Description6-hydroxy-4-({2-[(2-hydroxyethyl)[3-(4-nitrophenyl)propyl]amino]ethyl}imino)-1,3-dimethyl-1,2,3,4-tetrahydropyrimidin-2-one belongs to the class of organic compounds known as phenylpropylamines. Phenylpropylamines are compounds containing a phenylpropylamine moiety, which consists of a phenyl group substituted at the third carbon by an propan-1-amine. Based on a literature review very few articles have been published on 6-hydroxy-4-({2-[(2-hydroxyethyl)[3-(4-nitrophenyl)propyl]amino]ethyl}imino)-1,3-dimethyl-1,2,3,4-tetrahydropyrimidin-2-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). Nifekalant is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nifekalant 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.
