compromising weed control efficacy. Alternatively, herbicide safeners may effectively improve herbicide selectivity. To address tembotrione-induced Zea mays injury, a series of novel ester-substituted cyclohexenone derivatives were designed using the fragment splicing method. In total, 35 title compounds were synthesized via acylation reactions. All the compounds were characterized using infrared spectroscopy
Tembotrione 是一种 4-羟基苯基丙酮酸双加氧酶 (HPPD) 抑制剂,已广泛用于多种植物。已报道 Tembotrione 可能对某些玉米杂交种造成伤害和植物死亡。安全剂与除草剂共同使用以保护某些作物而不影响杂草控制效果。或者,除草剂安全剂可以有效地提高除草剂的选择性。为了解决环硫酮诱导的玉米损伤,采用片段拼接法设计了一系列新型酯取代环己烯酮衍生物。通过酰化反应总共合成了 35 种标题化合物。所有化合物均通过红外光谱、1 H 和13C核磁共振波谱和高分辨率质谱。使用单晶 X 射线衍射确认化合物II-15的构型。生物活性测定证明,大多数标题化合物都可以降低 tembotrione 对玉米的植物毒性。特别是,化合物II-14表现出最高的抗环硫酮活性。分子结构比较以及吸收、分布、代谢、排泄和毒性预测表明,化合物II-14表现出与商业安全剂异恶草醚相似的药代动力学特性。分子对接模型表明化
