concentration is critical to human health and diseases. Here we report the design, syntheses, and biological applications of HKPerox-Red and HKPerox-Ratio for quantitative measurement of H2O2. Both probes were successfully applied to detect endogenous H2O2 fluxes in living cells or zebrafish, and biological effects of multiple stress inducers including rotenone, arsenic trioxide, and starvation were
过氧化氢(H 2 O 2)在氧化还原信号和氧化应激中起重要作用,其动态浓度对人类健康和疾病至关重要。在此,我们报告HKPerox-Red和HKPerox-Ratio的设计,合成及其在H 2 O 2定量测量中的
生物学应用。两种探针均成功地用于检测活细胞或斑马鱼中的内源性H 2 O 2通量,并研究了
鱼藤酮,
三氧化二砷和饥饿等多种应激诱导物的
生物学效应。作为H 2 O 2是氧化酶氧化的常见副产物,已开发出一种通用检测方法,可用于各种代谢物(
葡萄糖,
尿酸和
肌氨酸)的超灵敏检测。此外,通过将流式细胞仪与活细胞校准相结合,首次实现了细胞H 2 O 2的测量。这项研究为高级H 2 O 2
生物成像和分析开发提供了一对独特的分子工具。
