초록
2,3,6-Tribromo-4,5-dihydroxybenzyl methyl ether (TDB) from the methanolic extract of the red alga Symphyocladia latiuscula exhibits major antioxidant activity. In this study, the activity of TDB against oxidative damage in deoxyribose and DNA was investigated in vitro for potential applications in preventing mutagenesis caused by DNA damage. TDB inhibited the oxidation of deoxyribose at concentrations of up to 1g/mL in the presence of Fe+3-EDTA/H2O2. Further-more, TDB showed no prooxidant activity as determined by absence of the reduction of bleomycin-Fe+3 to bleomycin-Fe+2, which leads to DNA damage. Based on these results, TDB demonstrated considerable antioxidant activity without prooxidant properties
