Metabolite Identification
Common NameCenthaquine
Description2-{2-[4-(3-methylphenyl)piperazin-1-yl]ethyl}quinoline belongs to the class of organic compounds known as phenylpiperazines. Phenylpiperazines are compounds containing a phenylpiperazine skeleton, which consists of a piperazine bound to a phenyl group. Based on a literature review very few articles have been published on 2-{2-[4-(3-methylphenyl)piperazin-1-yl]ethyl}quinoline. This compound has been identified in human blood as reported by (PMID: 31557052 ). Centhaquine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Centhaquine 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.
