A series of twelve 2,5-bis(alkylamino)-1,4-benzoquinones were prepared in yields ranging from 9-58% via the reaction between p-benzoquinone and various amines. The structures of the synthesized compounds were confirmed by IR, 1H- and 13C-NMR and MS analyses. The phytotoxicity of the 2,5-bis(alkylamino)-1,4-benzoquinones was evaluated against two crop species, Cucumis sativus and Sorgum bicolor, at
通过对苯醌与各种胺之间的反应,以 9-58% 的产率制备了一系列 12 种 2,5-双(烷基氨基)-1,4-苯醌。合成化合物的结构通过IR、1H-和13C-NMR和MS分析证实。2,5-双(烷基氨基)-1,4-苯醌对两种作物物种、Cucumis sativus 和双色高粱的植物毒性进行了评估,浓度为 1.0 x 10(-3) mol/L。一般来说,醌类对双子叶植物 C. sativus (7-74%) 显示出抑制作用。另一方面,在双色链球菌(单子叶植物)上观察到刺激作用。在对杂草物种 Ipomoea grandifolia(双子叶)和 Brachiaria decumbens(单子叶)进行的生物测定中观察到类似的结果。此外,2,5-双(烷基氨基)-1的细胞毒性,4-苯醌针对 HL-60(白血病)、MDA-MB-435(黑色素瘤)、SF-295(脑)和 HCT-8(结肠)人癌细胞系和人外周血单核细胞
