- Abstract
- In the present study, the antioxidative properties of tectorigenin, a metabolite formed by transformation of tectoridin by intestinal microflora, were investigated. Tectorigenin was found to scavenge intracellular reactive oxygen species, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, and thus prevented lipid peroxidation. The radical scavenging activity of tectorigenin protected the viability of Chinese hamster lung fibroblast (V79-4) cells exposed to hydrogen peroxide (H2O2) via activation of extracellular signal regulated kinase (ERK) pathway. Furthermore, tectorigenin reduced the apoptotic cells formation and cell cycle arrest at G2/M phase induced by H2O2. Tectorigenin increased the activities of cellular antioxidant enzymes like superoxide dismutase, catalase, glutathione peroxidase, and also increased their protein level. Taken together, these findings suggest that tectorigenin protected V79-4 cells against H 2O2 damage, by enhancing the antioxidative activity and by activating ERK pathway. © 2005 Elsevier B.V.
