The human colon adenocarcinoma-derived cell line CaCo-2 was used as a model
system to study the effects of copper (II), tetradentate N-alkyl ligand (H
2L) and their complex. The stimulatory effect of the complex was obtained w
ith lower concentrations from 10(-7) to 10(-17) mol.L-1 while inhibiting ef
fects occur from 10(-4) to 10(-6) mol.L-1. According to this study, copper
(II) and free ligand were toxic for cultured cells. Our data suggested that
the complex, according to our toxicity assays in mice, could be used as an
antimitotic agent.
