In the present work, we measured survival and the platinum on the genome after treatment of repair-proficient or repair-deficient Escherichia coli strains with trans-[PtCl(2)(E-iminoether)(2)] and compared these results with the effects of "classical" cisplatin. We found that toxicity of antitumor trans-[PtCl(2)(E-iminoether)(2)] in repair-deficient trains was much less than that of cisplatin. This markedly reduced toxicity was not a consequence of the reduced uptake or low levels of DNA binding in the bacteria cells but rather appeared to reflect DNA binding mode of this trans-platinum drug different from that of cisplatin.
