inhibit biofilm formation 2- to 4-times more than both reference drugs. Compounds were evaluated also for their antifungal activity against eight species. The evaluation revealed that all compounds exhibited antifungal activity better than the reference drugs bifonazole and ketoconazole. Molecular docking studies on antibacterial and antifungal targets were performed in order to elucidate the mechanism
背景:传染病象征着全球对公共卫生安全造成的后果性压力,并对世界各地的社会经济稳定产生影响。对当前抗菌治疗的耐药性日益增加,迫切需要发现和开发具有不同作用模式的感染治疗新实体,这些实体可以同时针对敏感菌株和耐药菌株。方法:使用有机合成的经典方法合成化合物。结果:所有 20 种合成化合物均显示出对 8 种革兰氏阳性和革兰氏阴性细菌的抗菌活性。应该提到的是,所有化合物对所有测试的细菌都表现出比氨苄青霉素更好的抗菌效力。此外,18 种化合物似乎比链霉素更有效地对抗金黄色葡萄球菌、阴沟肠杆菌、铜绿假单胞菌、单核细胞增生李斯特菌和大肠杆菌。三种最活跃的化合物 4h、5b 和 5g 似乎比氨苄青霉素更有效地对抗 MRSA,而链霉素没有显示任何杀菌活性。与氨苄青霉素相比,所有三种化合物对铜绿假单胞菌和大肠杆菌的耐药菌株也显示出更好的活性。此外,所有化合物都能够比两种参考药物抑制生物膜形成多 2 到 4 倍
