| Abstract: | There was no direct inhibition of DNA synthesis in ascites hepatoma 22A cells after intraperitoneal injection of single doses of copper (II) complexes with amino acids into tumor-bearing C3HA mice. Meanwhile cis-dichlorodiamine platinum (II) (DDP) as well as sarcolysine showed such inhibition. Copper (II) complexes with alpha-amino acids displayed as significant superoxide dismutase-like activity at concentrations corresponding to therapeutic doses of these compounds. The complexes of copper (II) combined with DDP give an additive antitumor effect in solid tumors of mice. |
