Metabolite Identification
Common NamePradefovir
Description2-{[2-(6-amino-9H-purin-9-yl)ethoxy]methyl}-4-(3-chlorophenyl)-1,3,2λ⁵-dioxaphosphinan-2-one belongs to the class of organic compounds known as 6-aminopurines. These are purines that carry an amino group at position 6. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. Based on a literature review very few articles have been published on 2-{[2-(6-amino-9H-purin-9-yl)ethoxy]methyl}-4-(3-chlorophenyl)-1,3,2λ⁵-dioxaphosphinan-2-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pradefovir is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pradefovir 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.
