This paper deals with two categories of compounds having the capacity to inhibit the neoplastic effects of chemical carcinogens on the host. The first are inducers of increased microsomal mixed function oxidase activity. An increasing number of these inducers are being found in natural products.
Dietary constituents of 2 types have been shown to affect the metabolism of chemical carcinogens by the microsomal mixed-function oxidase system. Naturally occurring inducers of increased activity of this system are present in plants. Cruciferous vegetables including Brussels sprouts, cabbage, and
Eighteen-month-old female mice were fed defined diets for 2 weeks which contained 0.05% or 0.10% oltipraz, 0.10% anethole dithione (ADT), 0.10% butylated hydroxyanisole (BHA) or 20% lyophilized cabbage. All diets resulted in significant increases in hepatic reduced glutathione (GSH) content.
The effect of two different doses (400 and 800 mg/kg body wt/day for 15 days) of a 95% ethanolic extract of the seeds of Brassica compestris (var sarason) was examined on carcinogen metabolizing phase-I and phase-II enzymes,antioxidant enzymes and glutathione content and lipid peroxidation in the
