molecule. These compounds were evaluated for antimicrobial activities. Docking simulations have been performed to position compounds into the FtsZ active site to determine their probable binding models. All of the compounds exhibited better antibacterial activities. Interestingly, compound 5c and 5d exhibited better antibacterial activities with IC 50 values of 0.03 and 0.05 μmol/mL against Staphylococcus
摘要 设计了七种靛红衍生物,并通过单晶X射线衍射、 1 H NMR、MS和元素分析对其化学结构进行了表征。结构稳定,然后是分子内和分子间 H 键,使这些分子成为分子识别中与单个分子内的自互补供体和受体单元的完美例子。评价这些化合物的抗微生物活性。已执行对接模拟以将化合物定位到 FtsZ 活性位点,以确定它们可能的结合模型。所有化合物均表现出较好的抗菌活性。有趣的是,化合物5c和5d对金黄色葡萄球菌表现出更好的抗菌活性,IC 50 值分别为0.03和0.05 μmol/mL。
