Free radical scavenging activity of flavonyl-thiazolidine-2,4-dione compounds has been evaluated using chemiluminescence, electron spin resonance spectroscopy with 5,5-dimethyl-1-pyrroline-1-oxide as spin trap and DPPH (2,2′-diphenyl-1-picrylhydrazyl) method. The examined compounds exhibited 28–50% scavenging superoxide anion radical (), 16.7–76.7% hydroxyl radical (HO•) and 9–40% DPPH radical. Compounds containing carbonyl group in their structure can be considered as antioxidants with high relevance and great biological importance. Copyright © 2009 John Wiley & Sons, Ltd.
采用化学发光法、以 5,5 二甲基-1-吡咯啉-1-氧化物为自旋阱的电子自旋共振光谱法和 DPPH(2,2′-二苯基-1-苦基肼)法评估了黄酮噻唑烷-2,4-二酮化合物清除自由基的活性。所研究的化合物对超氧阴离子自由基()的清除率为 28-50%,对羟自由基(HO-)的清除率为 16.7-76.7%,对 DPPH 自由基的清除率为 9-40%。结构中含有羰基的化合物可被视为具有高度相关性和重要生物学意义的抗氧化剂。Copyright © 2009 John Wiley & Sons, Ltd. All Rights Reserved.
