Metabolite Identification
Common NamePamapimod
Descriptionpamapimod, also known as R1503 or ro 4402257, belongs to the class of organic compounds known as diarylethers. These are organic compounds containing the dialkyl ether functional group, with the formula ROR', where R and R' are aryl groups. Based on a literature review a significant number of articles have been published on pamapimod. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pamapimod is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pamapimod 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.
