Common Name1-(2-Chloro-4-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-propylurea
Description1-(2-Chloro-4-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-propylurea, also known as KRN 633, 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 very few articles have been published on 1-(2-Chloro-4-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-propylurea. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-(2-chloro-4-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-propylurea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-(2-Chloro-4-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-propylurea 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.
