Abstract

The protective effects of 3,3″-di-OH-terphenyllin (3,3″-DHT) and 3-OH-terphenyllin (3-HT), two secondary metabolites produced by Aspergillus candidus (CCRC31543), against hydrogen peroxide-induced oxidative damage to Int 407 cells, were evaluated. The results showed that H 2O 2 caused an increase in lactate dehydrogenase (LDH) leakage and DNA damage in Int 407 cells; however, the addition of 3,3″-DHT and 3-HT significantly reduced this effect (P0.05), but oxidized glutathione levels increased when Int 407 cells were pre-incubated with these two compounds. These findings suggest that 3,3″-DHT and 3-HT have the ability to protect against oxidative damage to Int 407 cells and that this protective effect may be associated with the ability to reduce ROS formation and increase catalase activity.
