摘要:原卟啉原氧化酶(ppo,Ec 1.3.3.4)是几种结构多样的除草剂的主要作用靶标.作为我们在开发新的抑制ppo的除草剂方面的研究工作的延续,一系列新型的3-(2'-卤代5'-取代-苯并噻唑-1'-基)-1-甲基-6-(三氟甲基) )设计并合成了嘧啶-2,4-二酮9.生物测定结果表明,许多新合成的化合物对烟草ppo(mtppo)的抑制活性均高于对照,苯氟磺草胺和次磺隆.化合物9F-5被确定为最有效的抑制剂,对mtppo的ki值为0.0072μm,分别显示出比次磺隆(ki = 0.03μm)和沙氟芬那西(ki = 0.01μm)高约4.2倍和1.4倍的效力.另外的温室分析表明,化合物9F-6(ki = 0.012μm)甚至在低至37.5 G活性成分(ai)/ Ha的浓度下,仍显示出最有希望的出苗后除草活性,具有广谱性.玉米在150 G Ai / Ha的剂量下表现出对化合物9F-6的相对耐受性,但是即使在75
