Complexes 1–6 -induced DNA damage in Hep-G2 cells.

Cells were treated with complexes 1 (8 μM), 2 (15 μM), 3 (5 μM), 4 (18 μM), 5 (28 μM) and 6 (14 μM) with the indicated concentrations for 24 h and analyzed by comet assay, respectively. The length of the tail reflects the DNA damage in Hep-G2 cells.
