Abstract: A series of synthesized quinoxalinone compounds have been investigated for their inhibition of lipid peroxidation. The activity data of in vitro and in vivo inhibition of lipid peroxidation has been obtained. These quinoxalinone compounds were found to have excellent antioxidant activity. 2-(3-(3-methoxy-4-hydroxystyryl)-2-oxoquinoxalin-1(2H)-yl) acetic acid showed appreciable antioxidant properties, much more potent than other tested compounds, with the inhibition value of 57.7%. Further structure activity relationship analysis demonstrates the importance of the para-hydroxystyryl structure for the quinoxaline derivatives in the antioxidant activity.

Key words: organic compounds, quinoxalinone, antioxidant, pharmaceuticals

摘要: 研究了一系列先前合成的喹喔啉化合物的抑制脂质过氧化活性,实验得到了这些化合物的体内和体外脂质过氧化抗氧化活性数据,发现这类喹喔啉化合物具有优异的抗氧化活性,其中,脂质过氧化清除率最高的化合物是2-(3-(3-甲氧基-4-羟基苯基)-2氧喹喔啉-1(2H)-烷基)乙酸,它在浓度为100μmol/L时,对应的清除率达到了57.7%。构效关系研究认为对羟基苯乙烯这一结构单元对于喹喔啉化合物在提高抗氧化活性有重要意义。
