| Common Name | benzo(e)pyrene |

| Description | Benzo[e]pyrene, also known as 1,2-benzpyrene or b(e)p, belongs to the class of organic compounds known as benzopyrenes. These are organic compounds containing a benzene fused to a pyrene(benzo[def]phenanthrene) ring system. Benzo[e]pyrene is possibly neutral. Benzopyrene is one of over 100 different polycyclic aromatic hydrocarbons (PAHs). Benzo[e]pyrene is a potentially toxic compound. They are usually found as a mixture containing two or more of these compounds. PAH metabolism occurs in all tissues, usually by cytochrome P-450 and its associated enzymes. PAHs are metabolized into reactive intermediates, which include epoxide intermediates, dihydrodiols, phenols, quinones, and their various combinations. PAHs are carcinogens and have been associated with the increased risk of skin, respiratory tract, bladder, stomach, and kidney cancers. They may also cause reproductive effects and depress the immune system. The phenols, quinones, and dihydrodiols can all be conjugated to glucuronides and sulfate esters; the quinones also form glutathione conjugates. The ability of PAH's to bind to blood proteins such as albumin allows them to be transported throughout the body. These enzymes metabolize PAH's into their toxic intermediates. benzo(e)pyrene is found in Nicotiana tabacum. benzo(e)pyrene was first documented in 2014 (PMID: 24812998). The reactive metabolites of PAHs (epoxide intermediates, dihydrodiols, phenols, quinones, and their various combinations) covalently bind to DNA and other cellular macromolecules, initiating mutagenesis and carcinogenesis (PMID: 25903191). |
