我们报告了 Naphtho-Peroxyflor-1 (NPF1) 的合成、性质和细胞应用,这是一种基于发红光萘并荧光素平台的新型过氧化氢荧光指示剂。由于其硼酸盐笼,NPF1 对过氧化氢具有对一组生物相关活性氧 (ROS)(包括超氧化物和一氧化氮)的高选择性,以及可见光谱远红区域(> 600 nm)的激发和发射曲线。 RAW264.7 巨噬细胞中的流式细胞术实验表明,NPF1 可以报告活细胞中过氧化物水平的变化。
We report the synthesis, properties, and cellular application of Naphtho-Peroxyfluor-1 (NPF1), a new fluorescent indicator for hydrogen peroxide based on a red-emitting naphthofluorescein platform. Owing to its boronate cages, NPF1 features high selectivity for hydrogen peroxide over a panel of biologically relevant reactive oxygen species (ROS), including superoxide and nitric oxide, as well as excitation and emission profiles in the far-red region of the visible spectrum (>600 nm). Flow cytometry experiments in RAW264.7 macrophages establish that NPF1 can report changes in peroxide levels in living cells.
