Metabolite Identification
Common NameOlaparib
DescriptionOlaparib, also known as lynparza or azd-2281, belongs to the class of organic compounds known as phthalazinones. Phthalazinones are compounds containing a phthalazine bearing a ketone group. Based on a literature review a significant number of articles have been published on Olaparib. This compound has been identified in human blood as reported by (PMID: 31557052 ). Olaparib is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Olaparib 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.
