precursors were tested against a broad panel of bacteria and were found to display Gram-positive selective, growth inhibitory activity (μM), indicating that this approach is suitable for the convergent syntheses and screening of novel sideromycins.
通过制备铁载体去铁胺 B 的马来酰亚胺连接衍生物,并将相应的 Ga 3+复合物与新鲜制备的含硫醇的抗生素:氯卡头孢菌素、环丙沙星和那氟沙星反应,合成了三种铁载体-药物偶联物(铁霉素)。结合物及其合成前体针对广泛的细菌进行了测试,发现显示出革兰氏阳性选择性生长抑制活性 (μM),表明这种方法适用于会聚合成和筛选新型铁霉素。
