A series of 2,5-substituent hydroquinone derivatives were designed and synthesized. Their structures were identified by elemental analysis, 1H NMR, IR spectra. Their assayed antibacterial (Escherichia coli, Bacillus subtilis) and antifungal (Candida albicans) activities were also evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method. The results of biological test showed compounds 1 and 10 have favorable antimicrobial activity with MICs of 20.5, 24.6, 18.9 and 28.6 μg/mL against Escherichia coli and Bacillus subtilis, respectively.
设计并合成了一系列2,5-取代的对苯二酚衍生物。通过元素分析、1H NMR和红外光谱确定其结构。还通过MTT(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴化物)法评估了它们的抗菌(大肠杆菌, 枯草芽孢杆菌)和抗真菌(白色念珠菌)活性。生物测试结果显示,化合物1和10对大肠杆菌和枯草芽孢杆菌具有良好的抗微生物活性,其最低抑菌浓度(MIC)分别为20.5、24.6、18.9和28.6 μg/mL。
