A novel fluorescent probe 8-HB was developed with a BODIPY as a fluorophore and 8-substituted hydrazine as a reactive site for sensitive and selective detection of nitric oxide (NO), generating major fluorescent dehydrazinated BODIPY and minor non-fluorescent azide BODIPY. Moreover, 8-HB can achieve specific imaging of endogenous NO in living cells.
开发了一种新型荧光探针8-HB,其中BODIPY作为荧光团,而8-取代的
肼作为反应位点,用于敏感和选择性地检测
一氧化氮(NO),生成主要的荧光脱
水肼BODIPY和次要的非荧光
叠氮化物BODIPY。此外,8-HB可以实现活细胞中内源性NO的特异性成像。
