摘要
以３种钌卟啉［Ｒｕ（ＴＰＰ）（ＣＯ），Ｒｕ（ＯＥＰ）（ＣＯ），Ｒｕ（４－Ｃｌ－ＴＰＰ）（ＣＯ）］作为超氧化物歧化酶（ＳＯＤ）和过氧化氢酶（ＣＡＴ）双功能模拟酶．核黄素－蛋氨酸光照法证实它们在１０－６～１０－５ｍｏｌ·Ｌ－１浓度范围内有清除Ｏ－·２的作用；分光光度法证实它们能催化Ｈ２Ｏ２的分解，且分解率随浓度增大而增大；用小鼠肝匀浆法测定Ｒｕ（ＴＰＰ）（ＣＯ）、ＳＯＤ和ＣＡＴ。
In this article ,three Ru porphines[Ru(TPP)(CO),Ru(4 Cl TPP)(CO),Ru(OEP)(CO)]were considered as two mimic of superoxide dismutaes(SOD) and catalase (CAT).The catalytic efficiency of them on the disproportionaion of O 2 -· have been proved by using riboflavin methionine photoreduction method in the concentration range of 10 -6 ～10 -5 mol·L -1 .The catalytic efficiency of them at decomposing H 2O 2 have been performed by spectrophotometry.The percentage of decomposing H 2O 2 while the increasing the concentration of the imitating compounds.The lipid peroxidation produced in liver homogenated of mice was determined by spectrophotometry detecting the content of MDA.
