Endogenous hydrogen peroxide in vivo is related to many diseases, including cancer, diabetes, cardiovascular disease, and neurodegenerative disorders. Although many probes for detection of H2O2 have been explored, rapid response probes are still expected for in vivo application. Here, a new probe (PAM-BN-PB) was designed based on an intramolecular charge transfer (ICT) process with three parts: phenanthroimidazole
体内内源性过氧化氢与许多疾病有关,包括癌症,糖尿病,心血管疾病和神经退行性疾病。尽管已经探索了许多用于检测H 2 O 2的探针,但是仍然期望在体内应用快速反应探针。在这里,基于分子内电荷转移(ICT)过程设计了一种新的探针(PAM-BN-PB),该过程分为三个部分:菲并咪唑,苄腈和硼酸苯酯。通过对PAM-BN-PB进行ICT调制处理,可以选择性地检测溶液系统中的H 2 O 2。外源性和内源性H 2 O 2 在正常的活细胞,缺血再灌注损伤细胞和动物中,都可以通过PAM-BN-PB成像。
