title: [Specific binding of a synthetic antioxidant from a series of spatially screened phenols, H3-phenozan, with isolated rat enterocytes].
abstract: Specific binding of gamma-(4 hydroxy-3,5-ditret. butyl-phenol) propionate (phenozan), a synthetic water-soluble screened phenol with antioxidant activity, with isolated rat enterocytes has been demonstrated. The Scatchard analysis of binding isotherms revealed two types of 3H-phenozan binding sites. It is concluded that the effect of synthetic screened phenol antioxidants on cellular activity is the result of two mechanisms of action--alteration of physicochemical properties of membrane lipids caused by the inhibitors of free-radical reactions and specific binding of these compounds to cell plasma membranes.
