Metabolite Identification
Common NameMyotoxin A
DescriptionMyotoxin A belongs to the class of organic compounds known as trichothecenes. These are sesquiterpene mycotoxins structurally characterized by the presence of an epoxide ring and a benzopyran derivative with a variant number of hydroxyl, acetyl, or other substituents. The most important structural features causing the biological activities of trichothecenes are the 12,13-epoxy ring, the presence of hydroxyl or acetyl groups at appropriate positions on the trichothecene nucleus and the structure and position of the side-chain. Based on a literature review a significant number of articles have been published on Myotoxin A. This compound has been identified in human blood as reported by (PMID: 31557052 ). Myotoxin a is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Myotoxin A 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.
