α-氧代膦酸衍生物生物活性机理的探讨──O,O-二甲基-α-[2,4-二氯苯氧丙酰氧基]丙基膦酸酯对绿豆幼根抗氧化酶的影响

Study on mechanism of biological activities of α-oxophosphonic acid derivatives──Effects of α-oxophosphonic acid derivatives (HJCE) on antioxidase of mung bean roots

以不同浓度O，O-二甲基-α-［2，4-二氯苯氧丙酰氧基］丙基膦酸酯处理绿豆幼根，其过氧化物酶（POD）、超氧化物歧化酶（SOD）活性及其同工酶均发生相应变化，高浓度HJCE对POD和SOD均有较强的抑制作用，低浓度则对其抑制较弱或有一定的激活作用．同时，不同浓度的HJCE对绿豆幼根细胞相对存活率也有相似的影响．

Mung bean roots were treated with various concentration of HJCE. Both the activity and isoenzyme of their peroxidase (POD) and superoxide dismutase (SOD) changed respectively. The two enzymes were inhibited evidently in high concentrations of HJCE and increased slightly in low concentrations. In the meantime, various concentration of HJCE have the similiar effects on the survival rate of mung bean roots.
