Common Name | Octachlorodibenzofuran |

Description | 1,2,3,4,6,7,8,9-Octachlorodibenzofuran, also known as octachlorodibenzofuran or OCDF, belongs to the class of organic compounds known as polychlorinated dibenzofurans. These are organic compounds containing two or more chlorine atoms attached to a dibenzofuran moiety. However, there were no permanent liver changes or definite liver damage found in people who ingested CDFs. 1,2,3,4,6,7,8,9-Octachlorodibenzofuran is an extremely weak basic (essentially neutral) compound (based on its pKa). 1,2,3,4,6,7,8,9-Octachlorodibenzofuran is a potentially toxic compound. Of these 135 compounds, those that contain chlorine atoms at the 2,3,7,8-positions of the parent dibenzofuran molecule are especially harmful. The resulting AhR mediated activation and alteration leads to body weight loss, cancer and thymic atrophy (characteristic of immune and endocrine disruption) which are common toxic responses to PCDFs and related toxic halogenated aryl hydrocarbons. Skin and eye irritations, especially severe acne, darkened skin color, and swollen eyelids with discharge are the most obvious health effects of the CDF poisoning. CDFs cause vomiting and diarrhea, anemia, more frequent lung infections, numbness and other effects on the nervous system, and mild changes in the liver. No information on the metabolism of dibenzofuran in mammalian organisms was found in the available literature. Halogenated dibenzofurans (PCDFs and PBDFs) bind the aryl hydrocarbon receptor (AhR), which increases its ability to activate transcription in the XRE (xenobiotic resoponse element) promoter region. Most CDFs are produced in very small amounts as unwanted impurities of certain products and processes utilizing chlorinated compounds. Chlorinated dibenzofurans (CDFs) are a family of chemical that contain one to eight chlorine atoms attached to the carbon atoms of the parent chemical, dibenzofuran. AhR signaling also increseases conversion of arachidonic acid to prostanoids via cyclooxygenase-2, alters Wnt/beta-catenin signaling downregulating Sox9 and alters signaling by receptors for inflammatory cytokines. This compound has been identified in human blood as reported by (PMID: 31557052 ). Octachlorodibenzofuran is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Octachlorodibenzofuran 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. |
