Metabolite Identification
Common NameEncequidar
DescriptionEncequidar belongs to the class of organic compounds known as aromatic anilides. These are aromatic compounds containing an anilide group in which the carboxamide group is substituted with an aromatic group. They have the general structure RNC(=O)R', where R= benzene, and R = aryl group. Based on a literature review a significant number of articles have been published on Encequidar. This compound has been identified in human blood as reported by (PMID: 31557052 ). Encequidar is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Encequidar 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.
