title: [Interaction of the complex copper compound Cu-2 with liver monooxygenases].
abstract: It has been shown that the antitumour drug Cu-2 (copper complex compound) inhibited the activity of liver monooxygenases in male CBA mice. The in vivo experiments have revealed a considerably increased duration of sleep in mice treated with hexenal after the administration of different Cu-2 doses. In vitro, after the incubation of intact mouse liver microsomal fractions with different concentrations of Cu-2 the level of cytochrome Y-450 was decreased and a non-active form of hemoprotein--cytochrome P-420--appeared. At the same time, after the incubation of Cu-2 with liver microsomal fractions stabilized by 20% glycerol type I spectral changes (Ks 330 microM) were registered. This shows the possible metabolism of Cu-2 by cytochrome P-450. The role of the revealed interaction of Cu-2 with liver microsomes is being discussed for the chemotherapy of cancer.
