environments. Therefore, the development of inhibitors that interfere with the bacterial fatty acid synthesis process is considered to be a promising tactic. In this study, 58 novel spirochromanone derivatives were prepared and their structure–activity relationship (SAR) was investigated. The bioassay results showed that all most of the compounds showed excellent biological activities, exampled by compounds
细菌的生存依赖于膜脂稳态,它能够调节脂质成分以适应和优化它们在不同环境中的生长。因此,干扰细菌脂肪酸合成过程的抑制剂的开发被认为是一种有前途的策略。在这项研究中,制备了 58 种新型螺环色满酮衍生物,并研究了它们的构效关系 (SAR)。生物测定结果表明,大多数化合物均表现出优异的生物活性,例如化合物B 14、C 1、B 15和B 13,它们对多种致病菌具有显着的抑制活性与EC0.78 μg/mL ∼3.48 μg/mL 的50 个值。通过一系列生化分析研究初步抗菌行为,包括但不限于荧光成像模式、GC - MS 分析、TEM 图像和荧光滴定实验。值得注意的是,化合物B 14降低了细胞膜的脂质含量,增加了细胞膜的通透性,从而破坏了细菌细胞膜的完整性。进一步的 qRT - PCR 结果表明化合物B 14干扰了脂肪酸合成过程中的 mRNA 表达水平-相关基因包括 ACC、ACP 和 Fab 家族基
