Metabolite Identification
Common NameTilmacoxib
Descriptiontilmacoxib, also known as JTE-522 or JTP-19605, belongs to the class of organic compounds known as phenyl-1,3-oxazoles. These are aromatic heterocyclic compounds containing a 1,3-oxazole substituted at one or more positions by a phenyl group. Based on a literature review a significant number of articles have been published on tilmacoxib. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tilmacoxib is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tilmacoxib 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.
