Macrocyclic Cu(II)tetraanhydroaminobenzaldehyde complex--antiproliferative activity in vitro and in vivo

The macrocyclic Cu(II)-tetraanhydroaminobenzaldehyde complex Cu(TAAB)C12 induces various cytotoxic effects in the dependence on a cell line, concentration and time of exposition. The highest complex concentration of 914 nmol/l induces degeneration of certain part of the HeLa cells population after 24 hours of cultivation. The concentration of 183 nmol/l causes a delayed cytotoxic effect on HeLa and HepG2 cells. After 24 hours of culturing 15.4-28.4% of cell population proliferated but after 48 and 72 hours 2.0-42.3% of the cell population degenerated. The cytotoxic effect on V79 cells is directly dependent on the actual concentration and time of the complex influence. The cytotoxic concentrations of Cu(TAAB)Cl2 induce an integrity damage of cytoplasmatic membrane and two phase unbalanced growth. Cu(TAAB)Cl2 possesses an antileukemic activity which at the dose of 10 mg/kg of body weight is not accompanied by side toxic effects on mice.
