class of selective anti-Helicobacter pylori agents, 2-oxo-2H-chromene-3-carboxamide derivatives, were prepared and evaluated for their anti-bacterial activity. All synthesized compounds showed little or no activity against different species of Gram-positive and Gram-negative bacteria and against various strains of pathogenic fungi. Some of them exhibited a potent and specific inhibitory effect on the growth
制备了一类新型的选择性抗幽门螺杆菌药物2-oxo-2H-苯甲基-3-羧酰胺衍生物,并对其抗菌活性进行了评估。所有合成的化合物对不同种类的革兰氏阳性细菌和革兰氏阴性细菌以及各种病原真菌菌株都几乎没有或没有活性。其中一些在0.0039-16 microg / mL MIC范围内对幽门螺杆菌的生长表现出有效而特异性的抑制作用,包括对甲硝唑具有抗性的菌株。还通过锥虫蓝染料排除试验对最具活性的化合物作为抗H进行了细胞毒性筛选。幽门螺杆菌制剂。在检查其细胞毒性潜力的衍生物中,许多衍生物诱导了低细胞毒性作用。
