Broadened antibacterial activity was introduced to rhodanine derivatives targeting Mycobacterial tuberculosis enoyl-acyl carrier protein reductase (Mtb InhA) by recruiting feature of xacins to bring DNA Gyrase B inhibitory capability. This is significant for preventing further bacterial injections in the tuberculosis treatment. The most potent compound Cy14 suggested comparable bioactivity (IC50 = 3
通过募集Xacins的特征来赋予DNA促旋酶B抑制能力,将扩大的抗菌活性引入针对分枝杆菌结核烯酰酰基载体蛋白还原酶(Mtb InhA)的罗丹宁衍生物。这对于在结核病治疗中防止进一步的细菌注射具有重要意义。最有效的化合物Cy14建议具有与阳性对照相当的生物活性(Mtb InhA的IC50 = 3.18 µM; DNA促旋酶B的IC50 = 10 nM)。结构-活性关系的讨论和分子对接模型揭示了若丹宁部分和衍生的甲氧基在间位的重要性,指出了未来修饰的方向。
