Common Name2,3,7,8-Tetrachlorodibenzofuran
Description2,3,7,8-Tetrachlorodibenzofuran, also known as 2,3,7,8-TCDF or PCDF 83, 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. Specifically AhR binds to the PCDF, translocates it to the nucleus and together with hydrocarbon nuclear translocator (ARNT) and xenobiotic responsive element (XRE) increases the expression of CYP1A1 and aryl hydrocarbon hydroxylase (CYP1B1). However, there were no permanent liver changes or definite liver damage found in people who ingested CDFs. 2,3,7,8-Tetrachlorodibenzofuran is an extremely weak basic (essentially neutral) compound (based on its pKa). 2,3,7,8-Tetrachlorodibenzofuran is a potentially toxic compound. The CDF family contains 135 individual compounds with varying damaging health and environmental effects; those 2,3,7,8-substitued being particularly harmful. 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. Most CDFs are produced in very small amounts as unwanted impurities after use of chlorinated compounds. 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. Only a few of these 135 compounds have been produced and their properties (color, smell, taste, and toxicity) studied. 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. 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. No information on the metabolism of dibenzofuran in mammalian organisms was found in the available literature. CDFs cause vomiting and diarrhea, anemia, more frequent lung infections, numbness and other effects on the nervous system, and mild changes in the liver. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,3,7,8-tetrachlorodibenzofuran is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,3,7,8-Tetrachlorodibenzofuran 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.
