摘    要:合成了水杨酸铜络合物并分析了其组成,提纯了Tween-20,-40,-60,-80,并测定了它们在pH7.4的磷酸缓冲液中的CMC。用Cyt.c还原法分别测定了水杨酸铜络合物在不同介质中的SOD样活性。详细研究了表面活性剂与水杨酸铜络合物协同清除O-2的作用。观察到在胶束体系中水杨酸铜络合物的SOD样活性明显高于缓冲液体系无表面活性剂时的SOD样活性,表面活性剂本身也具有清除O-2的功能。抗红细胞膜脂质过氧化实验也得到类似结果。这可用胶束催化解释。水杨酸铜-Tween体系可能是一种潜在的抗炎药物。

关 键 词:超氧阴离子自由基;羟自由基;胶束催化;SOD样活性;铜络合物

Abstract:opper salicylate complex has been synthesized and its composition was analyzed. The four surfactants(Tween 20, 40, 60, 80) were purified and their critical micelle concentrations(CMC) in phosphate buffer (pH=7.4) were measured. The SOD like activity of copper salicylate complex was assayed using the cytochrome c reduction method in different media. The cooperative effect of the complex with micelles was studied in detail. SOD like activity of the complex was enhanced in the presence of surfactants. The four surfactants themselves display SOD like activities to a certain extent. Similar results were obtained in the experiment for the antilipid peroxidation of red cell membrane. These results might be explained by the fact of micellar catalysis. It was suggested that the copper salicylate Tween system used as a potential antiinflammatory drug might be worthwhile to be further studied.
Keywords:Superoxide anion radical  Hydroxide radical  Micellar catalysis  SOD like activity  Copper complex
