Cytotoxic activity of copper(II) complexes. Expressed as a percentage of the amount of untransformed resazurin to resorufin after 3 h of incubation with copper(II) complexes. Comparison with C+ control was performed by t-test Significance levels: ***0.000 < P < 0.001; **0.001 < P < 0.01; *0.01 < P < 0.05
