제목 Polymeric micellar nanoplatform for Fenton reaction as novel antibacterial therapeutics agents
초록 Reactive oxygen species produced by host phagocytes exert antibacterial action against pathogens. ROS-induced oxidative stress is the governing mechanism for the antibacterial activity of antibiotics. Especially, hydroxyl radical is a strong oxidant which can damage. Ferrous ion is known to convert H2O2 into hydroxyl radicals, referred to as Fenton reaction. Herein, we report a novel antibacterial agent composed of H2O2-generating polymer (PCAE) and iron-containing ferrocene. PCAE was designed to incorporate H2O2-generating cinnamaldehyde through acid-cleavable linkages and self-assemble to form micelles that encapsulate ferrocene. All the experiments in vitro display that ferrocene-loaded PCAE micelles produce hydroxyl radicals to kill E. coli and P. aeruginosa. In addtion, ferrocene-loaded PCAE micelles reduced the lung damages and therefore increased the survival rate of mice. We anticipate that ferrocene-loaded PCAE micelles hold great potential as a novel of antibacterial agents.
