DescriptionMethylchlorophenoxypropionic acid, also known as 4-chloro-2-methylphenoxy-a-propionate or 2-(4-chloro-2-tolyloxy)propionic acid, belongs to the class of organic compounds known as 2-phenoxypropionic acids. These are aromatic compounds hat contain a phenol ether attached to the C2-atom of a phenylpropionic acid. The affinity for the Ah receptor depends on the structure of the specific CDD. The major routes of excretion of CDDs are the bile and the feces, though smaller amounts are excreted in the urine and via lactation. Methylchlorophenoxypropionic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Methylchlorophenoxypropionic acid is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Mecoprop, or methylchlorophenoxypropionic acid (MCPP), is a common general use herbicide found in many household weed killers and weed-and-feed type lawn fertilizers. 2,3,7,8-Tetrachlorodibenzo-p-dioxin is also a known human carcinogen. The change in gene expression may result from the direct interaction of the Ah receptor and its heterodimer-forming partner, the aryl hydrocarbon receptor nuclear translocator, with gene regulatory elements or the initiation of a phosphorylation/dephosphorylation cascade that subsequently activates other transcription factors. CDDs are very slowly metabolized by the microsomal monooxygenase system to polar metabolites that can undergo conjugation with glucuronic acid and glutathione. It is primarily used to control broadleaf weeds. This compound has been identified in human blood as reported by (PMID: 31557052 ). Mecoprop is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Mecoprop 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.
