Resumo
Copper compounds exhibit interesting biological properties. Nitroimidazoles show radiosensitizer properties for
radiotherapy tumor treatment. In the present work, the effect of binding metronidazole (1-(2-hidroxyethyl)-2-
methyl-5-nitroimidazole = MTZ) to copper-acetate on the radiosensitizer properties has been investigated. A
compound of copper-acetate-MTZ was prepared and characterized. The experiments were carried out by
gamma-irradiation of Hep2 (human larynx cancer) cells under hypoxic conditions. The radiation doses for 50%
cell survival in the presence of radiosensitizer were about 8.2 Gy for CuAcMTZ or free MTZ. The effect of
binding metronidazole to copper acetate on radiosensitizer properties is mainly related to the radiosensitizer
process which involves two events for CuAcMTZ in contrast to one event observed for the MTZ free drug.
