Abstract: A comparative study on the genotoxic activity of cisplatin versus morfozol, the first representative of a new class of cation-anion complexes of palladium [AH] [PdCl ] (where A-methylmorpholine) has been performed using human lymphocytes in vitro. The results of the DNA-DNA cross-linking activity investigations showed that both compounds studied exhibited biphasic dose-effect relationship: a linear decrease in the DNA percent in the comet tail and the region of the "plateau". However, in the "plateau" region, morfozol reduced the DNA percent in the comet tail up to 6 times while cisplatin caused a 2-fold decrease only. Morfozol, like cisplatin, inducing DNA-protein cross-linking and generating reactive oxygen species, was more effective than cisplatin.
