    用于检测一氧化氮的一类小分子荧光探针及其应用
    摘要:
    本发明公开了用于检测一氧化氮的一类小分子荧光探针及其应用。该探针是基于邻苯二胺结构优化的探针构建策略,改变邻苯二胺反应基团与荧光团的连接结构以及邻苯二胺的不同取代基,提高对一氧化氮的灵敏度和响应速率;改变荧光团的结构,得到绿色可见光和近红外光区域具有不同荧光颜色的一氧化氮荧光探针,用于缓冲液中一氧化氮检测和活细胞中一氧化氮荧光成像。本申请设计的一氧化氮荧光探针构建策略的模块化和普遍性得到了系统验证。未来还可将邻苯二胺反应基团通过碳酰胺结构连接到更多不同波长和光学性质的荧光团上,从而方便快捷地开发一系列一氧化氮荧光探针。
