Quantitative Structure–Activity Analyses of Novel Hydroxyphenylurea Derivatives as Antioxidants
importance in governing the inhibitory potency. An increase in the electron donating property of substituents toward the phenolic hydroxyl group enhanced the antioxidative activity by the stabilization of an electron-deficient radical-type transition state. The steric shielding by ortho-substituents stabilized the phenoxyradicals formed following the transition state. Derivatives having the carboxyl group
