Metabolite Identification
Common NameIsamoxole
DescriptionIsamoxole, also known as LRCL 3950, belongs to the class of organic compounds known as 2,4-disubstituted oxazoles. 2,4-disubstituted oxazoles are compounds containing an oxazole ring substituted at positions 2 and 4 only. Oxazole is a five-membered aromatic heterocycle with one oxygen, one nitrogen, and three carbon atoms. Isomers include 1,2-oxazole and 1,3-oxazole. Based on a literature review a small amount of articles have been published on Isamoxole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isamoxole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isamoxole 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.
