The indiscriminate use of herbicides makes weeds resistant, increasing the demand for more efficient herbicides. Novel potential herbicides were prepared from sorbic acid, being 8 dienamides and 6 epoxides. Subsequently, phytotoxic activities of sorbic acid and 14 synthesized compounds were evaluated against sorghum, onion, cucumber, lettuce, and beggartick seeds. Furthermore, the protein target of
除草剂的滥用使杂草产生抗药性,增加了对更高效除草剂的需求。以山梨酸为原料,制备了8种二酰胺类和6种环氧化物类新型潜在除草剂。随后,评估了山梨酸和 14 种合成化合物对高粱、洋葱、黄瓜、生菜和 beggartick 种子的植物毒性活性。此外,通过计算机技术鉴定了植物中最活跃物质的蛋白质靶标。受试化合物中,(2E,4E)-N-(对氟苯基)六-2,4-二烯酰胺(2c)、(2E,4E)-N-(邻萘基)六-2,4-二烯酰胺( 2d),(E)-N-甲基苯基-3-((2R,3R)-3-甲基环氧乙烷-2-基)丙烯酰胺(3b),(E)-N-溴苯基-3-((2R,3R)- 3-甲基环氧乙烷-2-基)丙烯酰胺(3e)和(E)-N-甲氧基苯基3-((2R,3R)-3-甲基环氧乙烷-2-基)丙烯酰胺(3f)对芽和芽均表现出明显的抑制活性。根,使它们成为有前途的除草剂的候选者。所有化合物都改变了种子发育,并且化合物 2c、2d、3b、3e
