Small molecule antioxidants such as ascorbic acid (AscH(2)) prevent the oxidative damage of biological molecules by scavenging reactive oxygen species. A carbonyl-conjugated ene-diol structure is essential for the antioxidant activity of AscH(2). As such, we synthesized novel AscH(2) analogs containing a carbonyl conjugated ene-diol structure and evaluated their radical scavenging activities. When the 1,2-dihydroxyethyl group was removed, radical scavenging activity equal to AscH(2) was observed. Analogs containing an endocyclic nitrogen atom instead of a ring oxygen displayed higher radical scavenging activities than AscH(2). Therefore, the electron donating effect of the carbonyl conjugated ene-diol structure greatly increased the radical scavenging activity of AscH(2) analogs.
