Understanding the mechanism by which Artemisinin conjugated with phototheranostic probes for reducing side effects (AC-Pr-RSE) will guide endeavor to improve the therapeutic outcomes. Herein, the first report describes the application of a cytotoxic artemisinin derivative and N-methyliminodiacetic acid (MIDA) boronates conjugated with a naphthalimide fluorophore for the detection of H2O2 in the Golgi apparatus. A comparative analysis of the localization signals from the fluorescent artemisinin derivative and organelle-specific dyes uncovered that the Golgi apparatus functions as the primary site of its accumulation, which could efficiently enhance the intracellular reactive oxygen species (ROS) level and induce cell apoptosis. This work highlights the potential of AC-Pr-RSE study, which enables us to optimize the design of theranostic probes to improve their biological activities during oxidative stress.
