Derivatives 3-6 of stallimycin (distamycin A) rnodified a t the C-terminal amidine moiety and tethered to a bis-epoxyethyl moiety (as DNA alkylating unit) at the N-terminal position have been prepared and tested for in vitro cytotoxic activity against two different leukemik cell lines, K562 and L1210. None of the compounds without epoxide was active. A comparison of the biological activity related to the diepoxy compounds 3-6 with different non-basic amidine modified moieties, showed low activity for the carbamoyl and N-methyl carbamoyl derivatives (compounds 5 and 6, respectively), moderate activity for the amidoxime analogue 4, good activity for the cyanamidine derivative 3.
