(Ki = 0.011 µM) and I23 (Ki = 0.012 µM), which exhibit similar activities to that of mesotrione, a commercial HPPD herbicide (Ki = 0.013 µM). Furthermore, the newly synthesized compounds show significant greenhouse herbicidal activities against tested weeds at dosages of 150 g ai/ha. In particular, II4 exhibited high herbicidal activity for pre-emergence treatment that was slightly better than that
设计并合成了一系列芳氧基乙酸衍生物,作为4-羟基苯基丙酮酸双加氧酶(HPPD)抑制剂。初步的生物测定结果表明,这些衍生物是有前途的拟南芥HPPD(At HPPD)抑制剂,特别是化合物I12(K i = 0.011 µM)和I23(K i = 0.012 µM),其活性与市售甲基磺草酮相似。 HPPD除草剂(K i = 0.013 µM)。此外,新合成的化合物在150 g ai / ha的剂量下对被测杂草显示出显着的温室除草活性。特别是II4在芽前处理中表现出较高的除草活性,略高于甲基磺草酮。此外,化合物II4对于玉米田中150 g ai / ha的杂草防治是安全的,并且被确定为新型HPPD抑制剂除草剂的最有效候选者。本文所述的化合物可为设计新的抑制HPPD的除草剂及其修饰提供有用的指导。
