Metabolite Identification
Common NameSinitrodil
Description2-(4-oxo-3,4-dihydro-2H-1,3-benzoxazin-3-yl)ethyl nitrate belongs to the class of organic compounds known as benzoxazines. These are organic compounds containing a benzene fused to an oxazine ring (a six-membered aliphatic ring with four carbon atoms, one oxygen atom, and one nitrogen atom). Based on a literature review very few articles have been published on 2-(4-oxo-3,4-dihydro-2H-1,3-benzoxazin-3-yl)ethyl nitrate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Sinitrodil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Sinitrodil 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.
