除草剂安全剂可增强农作物的除草剂解毒作用,而不会降低其对目标杂草的除草功效。为了减轻磺酰脲类除草剂烟嘧磺隆对玉米的伤害,通过生物立体异构和活性亚基组合合理设计了一系列1,3-二取代的咪唑烷或六氢嘧啶衍生物。使用高效一锅法和低成本原料合成了30种新型化合物,并通过IR,1 H NMR,13进行了表征13 C NMR和高分辨率质谱仪(HRMS)。评估了生物活性和构效关系(SAR),以测试烟嘧磺隆伤害的除草剂安全剂。大多数化合物可有效保护敏感玉米免受烟嘧磺隆的损害。目标化合物的母体骨架和取代基都实质上影响了其安全性。与更安全的异恶二芬-乙基相比,化合物I-3表现出优异的生物活性。分子对接模拟表明,化合物I-3与烟嘧磺隆竞争乙酰乳酸合酶活性位点,并证明这是安全剂的保护机制。目标化合物I-3 在玉米中具有强大的除草剂安全剂活性,因此是开发新型除草剂安全剂的潜在候选者。
