title: 4-(4-R-phenylamino)-5-methoxy-1,2-benzoquinones are new selective inhibitors of carbon tetrachloride-initiated free radical reactions in liver.
abstract: The action of several 1,2-benzoquinone derivatives on free radical processes initiated by carbon tetrachloride was studied. Among them a substance that effectively inhibited lipid peroxidation without substantial influence on covalent binding of radical products of metabolic cleavage of carbon tetrachloride as well a substance that equally inhibited both processes were found. It was shown that 1,2-benzoquinones can be useful tool for investigation of free radical mechanisms of carbon tetrachloride-initiated liver cell damage in vivo.
