Novel derivatives of chromenone bearing an $N$-carbamothioyl moiety were synthesized and evaluated for their soybean 15-LOX inhibitory activity. Synthesis of the target compounds was started from 7-hydroxy-2$H$-chromen-2-one. It was reacted with 1-fluoro-2(4)-nitrobenzene to obtain the corresponding nitrophenoxy-chromenone derivative. Reduction of the nitro group was achieved in the presence of Zn/NH$_4}$Cl and reaction of the latter compound with in situ prepared benzoyl isothiocyanate led to the formation of the title compounds. All compounds were characterized and tested against soybean 15-LOX. Among them, 4-methyl-$N$-((4-((2-oxo-2$H$-chromen-7-yl)oxy)phenyl)carbamothioyl)benzamide (7l) showed the best activity as potent as the reference drug, quercetin.
合成了带有 N$-氨基硫酰基的色原酮新衍生物,并评估了它们对大豆 15-LOX 的抑制活性。目标化合物的合成从 7-hydroxy-2$H$-chromen-2-one 开始。它与 1-氟-2(4)-硝基苯反应,得到相应的硝基苯氧基苯并吡喃酮衍生物。在 Zn/NH$_4}$Cl 的存在下,硝基实现了还原,而后一种化合物与原位制备的异硫氰酸苯甲酰酯反应生成了标题化合物。对所有化合物进行了表征,并针对大豆 15-LOX 进行了测试。其中,4-甲基-$N$-((4-((2-氧代-2$H$-色烯-7-基)氧基)苯基)氨基硫酰基)苯甲酰胺(7l)显示出与参考药物槲皮素相同的最佳活性。
