- . Keywords: aryloxyacetic acid; herbicidal activity; 4-hydroxyphenylpyruvate dioxygenase; modification; synthesis; Introduction 4-Hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD), which belongs to the family of non-heme FeII-containing enzymes, is a vital enzyme for tyrosine catabolism. This enzyme
- 2,4-D and the 1,3-dicarbonyl unit, we designed and synthesized a series of novel aryloxyacetic acid derivatives. In this context, these derivatives were subjected to HPPD inhibition, herbicidal activity, crop safety and structure–activity relationship (SAR) studies. As expected, many of the title
