WebThe formation of cyclopenta ring oxides via monooxygenation of a fused cyclopenta ring is a major route of metabolic activation for the cyclopenta-fused PAH, such as cyclopenta[cd]pyrene (CPP). While pyrene is essentially a noncarcinogen, fusion of an ethylene moiety to the periphery creates CPP, a potent rodent carcinogen.
