  Effects of electron-withdrawing substituents on DPPH radical scavenging reactions of protocatechuic acid and its analogues in alcoholic solvents

  摘要：

  The DPPH (2,2-diphenyl-l-picrylhydrazyl) radical scavenging activity of protocatechuic acid (3,4-dihydroxybenzoic acid) and its related catechols was examined. Compounds possessing strong electron-withdrawing substituents showed high activity. NMR analysis of the reaction mixtures of catechols and DPPH radical in methanol showed the formation of methanol adducts. The results suggest that high radical scavenging activity of catechols in alcohol is due to a nucleophilic addition of an alcohol molecule on o-quinones, which leads to a regeneration of a catechol structure. Furthermore, the radical scavenging activity in alcohols would largely depend on the electron-withdrawing/donating substituents, Since they affect the susceptibility toward nucleophilic attacks on o-quinone.

  mostother natural licochalcones possess the group on ring B. Total synthesis of licochalcone D has not been reportedeven possessing the strongest anti-inflammatory activity. Therefore, the first total synthesis of licochalcone Dhas been developed by using water-accelerated [3,3]-sigmatropic rearrangement method.Key Words : Licochalcone D, Anti-inflammatory activity, Glycyrrhiza inflata, Water-accelerated
