exerted superior or comparable activity to all the reference drugs. In the cell division inhibitory activity, all the compounds showed the same trend as their in vitro antibacterial activity, exhibiting better activity against S. aureus ATCC25923 than the other strains. Additionally, compounds 3, 6, 7 and 8 displayed potent cell division inhibitory activity with an MIC value of below 1 μg/mL, over 256-fold
为了发现潜在的抗细菌耐药性增强剂,设计,合成和评估了新型肉桂醛衍生物作为FtsZ抑制剂,使用肉汤微稀释法评估了其对九种重要病原体的抗菌活性,以及它们对四种代表性菌株的细胞分裂抑制活性。在体外抗菌活性中,新合成的化合物一般对金黄色葡萄球菌ATCC25923显示出比其他化合物更好的功效。特别是化合物3,8和10发挥了优于所有参比药物的活性。在细胞分裂抑制活性中,所有化合物均显示出与其体外抗菌活性相同的趋势,与其他菌株相比,其对金黄色葡萄球菌ATCC25923的活性更好。此外,化合物3,6,7和8中显示强效的细胞分裂的抑制活性具有低于1微克/毫升,超过256倍更好所有参考药物的MIC值。
