there are two classes of anticarcinogenic enzyme inducers : ( a ) monofunctional inducers ( e.g. , phenolic antioxidants , isothiocyanates , coumarins , thiocarbamates , cinnamates , 1,2-dithiol-3-thiones ) that elevate phase ii enzymes ( such as glutathione s-transferases , nad ( p ) h : quinone reductase , udp-glucuronosyl-transferases ) in various tissues without significantly raising the phase i enzyme , aryl hydrocarbon hydroxylase ( cytochrome p1-450 ) ;
