Metabolite Identification
Common Name4-Quinolinamine, N-hydroxy-, 1-oxide
Description4-Quinolinamine, N-hydroxy-, 1-oxide, also known as 4 hydroxyaminoquinoline 1 oxide, belongs to the class of organic compounds known as hydroquinolines. These are derivatives of quinoline in which in which at least one double bond in the quinoline moiety are reduced by adding two hydrogen atoms. Based on a literature review very few articles have been published on 4-Quinolinamine, N-hydroxy-, 1-oxide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-quinolinamine, n-hydroxy-, 1-oxide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Quinolinamine, N-hydroxy-, 1-oxide 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.
