Metabolite Identification
Common NameFleroxacin
DescriptionFleroxacin, also known as megalocin or abbr fle, belongs to the class of organic compounds known as quinoline carboxylic acids. These are quinolines in which the quinoline ring system is substituted by a carboxyl group at one or more positions. Based on a literature review a significant number of articles have been published on Fleroxacin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Fleroxacin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Fleroxacin 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.
