COMPARAT IVE ANALYSIS OF GENOT OXIC EFFECT S OF NEW
PORPHYRINS IN COMET ASSAY IN VIVO
S u m ma r y
Comparative genotoxicity of new porphyrins TOEt4PyP and their Ag-,
Zn- and Co derivatives was estimated by Comet-assay in mice leukocytes
in vivo, depending on time of treatment. The increase of level of DNA
damage after 24 hours in comparison with 6 hours of porphyrins
administration confirms their cumulative effect, that can be applied in
chemotherapy of tumors.
