| Common Name | 1-Ethyl-1-nitrosourea |
|---|
| Description | N-ethyl-N-nitrosourea, also known as aethylnitroso-harnstoff or ENU, belongs to the class of organic compounds known as nitrosoureas. Nitrosoureas are compounds containing a nitro group and an urea group N-N linked together, with the general structure R1N(R2)C(=O)N(R3)N=O. Based on a literature review a significant number of articles have been published on N-ethyl-N-nitrosourea. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-ethyl-1-nitrosourea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-Ethyl-1-nitrosourea 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. |
