DescriptionPyrene, also known as beta-pyrene, belongs to the class of organic compounds known as pyrenes. Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. This colourless solid is the smallest peri-fused PAH (one where the rings are fused through more than one face). Pyrene results from the incomplete combustion of organic compounds, in a wide array of conditions. The aromaticity and peri-fused condition of pyrene make it a more stable combustion product than its isomer fluoranthene. PAH metabolism occurs in all tissues, usually by cytochrome P-450, specifically by its associated enzymes CYP1A1 and CYP1B1 (PMID: 14720319 ). These enzymes metabolize PAH's into their toxic intermediates. The metabolites of pyrene, such as phenols, quinones, and dihydrodiols, can all be conjugated to glucuronides and sulfate esters; the quinones also form glutathione conjugates. PAHs are generally considered as cancerogenic to varying degrees. They may also cause reproductive effects and depress the immune system. Pyrene is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ).
