(a) Intracellular ROS was detected in A375 cells after treatment with vehicle control and complexes for 24 h; (b) Quantification of the flow cytometric results in (a) showing the percentage of cells with increased intracellular DCF oxidation compared to control cells. Results are the mean ± S.E.M (n = 3) *p < 0.05, **p < 0.01, ***p < 0.001.
