A Confocal microscopy images of 4T1 cells after incubation with MTG and FEP or FEPT. Scale bar: 10 µm. B Intensity profiles of linear regions of interest between FEP or FEPT and MTG. Fluorescence imaging of C intracellular ROS burst production, and D JC-1 stained cells under different conditions. The cells were co-stained with DCFH-DA (10 µM) or JC-1 (2 µM). Scale bar: 20 μm
