1-芳基-3-(3-(4-氧香豆素基)苯基)硫脲衍生物的合成及抑菌活性
Synthesis and Antibacterial Activity of 1-Aryl-3-(3-((2-oxo-2H-Chromen-4-yl)oxy)phenyl)thiourea Derivatives
摘要
Abstract
In order to develop thiourea derivatives with antibacterial activities, a series of novel 1-aryl-3-(3-((2-oxo-2H-chromen-4-yl)oxy)phenyl)thiourea derivative was synthesized from 4-hydroxycoumarin via chlorination, etherification, isothiocyanate formation and addition reactions.The structures of the title compounds were characterized by infrared spectroscopy(IR), nuclear magnetic resonance spectrocopy(NMR) and mass spectrometry(MS).The results show that title compounds exhibit excellent antibacterial activities against Xanthomonas oryzae pv.oryzae(Xoo) and Xanthomonas citri subsp.Citri(Xcc).Among of them, compounds 4k, 4l, 4m and 4n show excellent antibacterial activities against Xoo, with the EC50 values 137.42, 131.05, 129.23 and 117.43 mg/L, respectively, which were better than that of the control agent thiodiazole-copper(195.24 mg/L).Compounds 4k, 4l, 4m and 4n display considerable antibacterial activities against Xcc, with the EC50 values of 97.02, 94.31, 102.28 and 90.52 mg/L, respectively, which are better than that of thiodiazole-copper(120.25 mg/L).关键词
