Metabolite Identification

Common Name

N,N'-Dimethylthiourea

Description

N,N'-dimethylcarbamimidothioic acid belongs to the class of organic compounds known as thioureas. These are organic compounds containing the thiourea functional group, a derivative of urea with the general structure (R1(N)R2C(=S)(R3)R4, R1-R4=H, alkyl, aryl), obtained by replacing the carbonyl group of urea with a thiocarbonyl group. Based on a literature review a significant number of articles have been published on N,N'-dimethylcarbamimidothioic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). N,n'-dimethylthiourea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N,N'-Dimethylthiourea 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.
