Metabolite Identification
Common NameAvosentan
DescriptionAvosentan belongs to the class of organic compounds known as pyridinylpyrimidines. Pyridinylpyrimidines are compounds containing a pyridinylpyrimidine skeleton, which consists of a pyridine linked (not fused) to a pyrimidine by a bond. Based on a literature review very few articles have been published on Avosentan. This compound has been identified in human blood as reported by (PMID: 31557052 ). Avosentan is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Avosentan 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.
