吲哚信号是细菌中普遍存在的信号网络之一。我们研究了去甲酰氟溴胺(dFBr)衍生物通过调节大肠杆菌和金黄色葡萄球菌的吲哚信号网络来抑制生物膜的形成。我们已经发现dFBr衍生物的活性是吲哚本身的10-1000倍,这表明氟曲明家族的吲哚天然产物代表了设计分子来控制致病菌行为的特权支架。
Indole signaling is one of the putative universal signaling networks in bacteria. We have investigated the use of desformylflustrabromine (dFBr) derivatives for the inhibition of biofilm formation through modulation of the indole-signaling network in E. coli and S. aureus. We have found dFBr derivatives that are 10-1000 times more active than indole itself, demonstrating that the flustramine family of indolic natural products represent a privileged scaffold for the design of molecules to control pathogenic bacterial behavior.
