摘要
介绍了脲嘧啶类除草剂的作用特点、机制及研究进展。脲嘧啶类除草剂属于原卟啉原氧化酶抑制剂。原卟啉原氧化酶在亚铁原卟啉与叶绿素生物合成中催化原卟啉原IX氧化成原卟啉IX,此种酶受到需光除草剂的专门抑制,迅速造成细胞受害与干枯。同时还介绍了研发此类化合物的创制经纬并对部分化合物的活性给以概述,为以后该类化合物的优化工作提供依据。
The development,mode of action,and features of uracil derivatives was discussed.Plant protoporphyrinogen oxidase（protox） catalyzes the oxidation of protoporphyrinogen IX to protoporphyrin IX in the biosynthesis of hemes and chlorophyll.This enzyme is specifically inhibited by light-dependent herbicides（protox inhibitors）.This paper made an overview about the biological activity of some compounds.The history of discovery and structure-activity relationship of protoporphyrinogen oxidase-inhibiting herbicides were summarized.
