Reactive oxygen species (ROS) often have significant roles in mediating redox modifications and other essential physiological processes, such as biological process regulation and signal transduction. Considering that H2O2 is a substantial member of ROS, detection and quantitation of H2O2 undertakes important but urgent responsibility. In this report, a bioluminescent probe for detecting H2O2 was well designed, synthesized, and evaluated. This probe was designed into three parts: a H2O2-sensitive aryl boronic acid, a bioluminescent aminoluciferin moiety, and a self-immolative linker. After extensive evaluation, this probe can selectively and sensitively react with H2O2 to release aminoluciferin. It should be pointed out that this probe is a potential bioluminescent sensor for H2O2 since it can provide a promising toolkit for real-time detection of the H2O2 level in vitro, in cellulo, and in vivo.
活性氧(ROS)在介导氧化还原修饰和其他重要生理过程(如生物过程调节和信号转导)中常常发挥重要作用。鉴于过氧化氢(H2O2)是ROS的重要成员,H2O2的检测和定量承担着重要但紧迫的责任。在本报告中,一种用于检测H2O2的生物发光探针被精心设计、合成和评估。该探针被设计为三个部分:一个对H2O2敏感的芳基硼酸、一个生物发光的氨基荧光素部分和一个自毁连接子。经过广泛评估,该探针能够选择性且灵敏地与H2O2反应以释放氨基荧光素。应当指出,该探针是一种潜在的H2O2生物发光传感器,因为它可为体外、细胞内和体内H2O2水平的实时检测提供一个有前景的工具包。
