benzopyrene

(bĕn′zō-pī′rēn′, -pī-rēn′)
n.
Either of two polycyclic aromatic hydrocarbons with the formula C20H12, found in coal tar and cigarette smoke and isolatable as a white or yellow crystalline solid. Both are hazardous, and one is known to be a potent carcinogen. Also called benzpyrene.

Four of these (anthracene, chrysene, benzopyrenes, and perylene; Table 4) were identified directly by comparison with results from their respective deuterated analogs.

Thus the monograph on benzopyrenes has a series of chapters on environmental occurence and analysis of these compounds.
Interestingly, the chemical degradation of the aromatic agent, complexed with vitamin [B.sub.2], was also reported with respect to another aromatic compound, the end metabolite of benzopyrene possessing carcinogenic activity [84].
Formation of such a complex, characterized by functional groups being spatially close to each other, promotes the participation of the phosphate group of FMN and the epoxy group of benzopyrene in further acid-catalyzed hydrolysis leading to the chemically inactive and noncarcinogenic tetraole [84].
