Common Name(1R,7S,13S,15S)-2,15-Dihydroxy-7-methyl-6-oxabicyclo[11.3.0]hexadeca-3,11-dien-5-one
Description(1R,7S,13S,15S)-2,15-Dihydroxy-7-methyl-6-oxabicyclo[11.3.0]hexadeca-3,11-dien-5-one, also known as ascotoxin or synergisidin, belongs to the class of organic compounds known as macrolides and analogues. These are organic compounds containing a lactone ring of at least twelve members. Based on a literature review very few articles have been published on (1R,7S,13S,15S)-2,15-Dihydroxy-7-methyl-6-oxabicyclo[11.3.0]hexadeca-3,11-dien-5-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). (1r,7s,13s,15s)-2,15-dihydroxy-7-methyl-6-oxabicyclo[11.3.0]hexadeca-3,11-dien-5-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (1R,7S,13S,15S)-2,15-Dihydroxy-7-methyl-6-oxabicyclo[11.3.0]hexadeca-3,11-dien-5-one 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.
