Benzo[a]pyrene-7,8-dihydrodiol-9,10-oxide, also known as BPDE or benzo(a)Pyrene diol epoxide, is classified as a member of the Pyrenes. Pyrenes are compounds containing a pyrene moiety, which consists four fused benzene rings, resulting in a flat aromatic system. Benzo[a]pyrene-7,8-dihydrodiol-9,10-oxide is considered to be practically insoluble (in water) and relatively neutral. It is a carcinogenic metabolite of benzo[a]pyrene (BaP) which forms adducts with DNA and proteins and is hydrolysed to BPDE tetrols. It is used as a marker for BaP exposure (a surrogate marker for PAHs). D009676 - Noxae > D002273 - Carcinogens D009676 - Noxae > D009153 - Mutagens
