Eleven amino‐substituted 1,4‐naphthoquinones were synthesized via the reaction of 1,4‐naphthoquinone with different primary and secondary mono‐ and diamines in the presence of dichloromethane ethanol (1:2) solvent at room temperature. All compounds were purified by flash column chromatography, characterized by TLC, HPLC, 13C‐NMR, 1H‐NMR, and FT‐IR spectral analysis and were evaluated in vitro for antifilarial
在室温下,在二氯甲烷乙醇(1:2)溶剂中,通过1,4-萘醌与不同的伯,仲单胺和二胺反应,合成了11个氨基取代的1,4-萘醌。所有化合物均通过快速柱色谱法纯化,通过TLC,HPLC,13 C-NMR,1 H-NMR和FT-IR光谱分析进行表征,并使用成年牛丝状蠕虫Setaria digitata进行体外抗丝虫活性评估。通过评估蠕虫蠕动和MTT(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴化物)的减少情况。11种化合物中的7种具有大丝杀菌活性,化合物9(2-[((1,3-二甲基丁基)氨基]萘-1,4-二酮)和11种(2-(4-甲基哌嗪-1-基)萘-1, 4-二酮)具有最大活性(48小时ED 50值分别为0.91和1.2 µM)。讨论了不同取代对抗丝活性的影响。Drug Dev Res2009。©2009 Wiley-Liss,Inc.
