CAS 218-01-9: Chrysene

Benzo[a]phenanthrene is a polycyclic aromatic hydrocarbon that is found in petroleum and coal tar. It has been shown to be a potent inducer of enzymes involved in the detoxification of xenobiotics, such as chrysene-inducible cytochrome P450 1A1 (CYP1A1), s-phenylmercapturic acid-inducible cytochrome P450 2E1 (CYP2E1), and benzo[a]pyrene-inducible glutathione S-transferase (GST). The optimum concentration for benzo[a]phenanthrene is determined by measuring the amount of enzyme activity in rat liver microsomes following the addition of benzo[a]phenanthrene. A fluorescence detector can be used to measure the fluorescence emission from benzo[a]phenanthrene at an excitation wavelength of 300 nm and an emission wavelength of 400 nm.
