Metabolite Identification
Common NameTriethylenephosphoramide
Description1-[bis(aziridin-1-yl)phosphoroso]aziridine, also known as TEPA or APO, belongs to the class of organic compounds known as organic phosphoramides. These are organic compounds containing the phosphoric acid amide functional group. Based on a literature review very few articles have been published on 1-[bis(aziridin-1-yl)phosphoroso]aziridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Triethylenephosphoramide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Triethylenephosphoramide 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.
