and Proteus vulgaris) and three fungal strains (Candida albicans, Cryptococcus terreus and Saccharomyces cerevisiae) by two-fold serial dilution technique. The results of bioactive assay showed that some of the synthesized coumarins displayed comparable or even better antibacterial and antifungal activities against tested strains in comparison with reference drugs erythromycin, novobiocin and amphotericin
合成了一系列4-甲基-7-O取代的香豆素(3-12),并评估了其对两种革兰氏阳性细菌(金黄色葡萄球菌和枯草芽孢杆菌),四种革兰氏阴性细菌(铜绿假单胞菌,大肠杆菌,肺炎克雷伯菌和寻常变形杆菌)和三种真菌菌株(白色念珠菌,土壤隐球菌和酿酒酵母)通过两次连续稀释技术进行鉴定。生物活性测定的结果表明,与参考药物红霉素,新霉素和两性霉素B相比,某些合成的香豆素对被测菌株显示出相当甚至更好的抗菌和抗真菌活性。化合物9对所检测的九种微生物菌株中的七种显示出有效的抗菌活性在这项研究中,MIC值介于1之间。09和25 µg / mL,是该系列中活性最高的化合物。本工作还描述了取代基对生物活性的影响。
