Patent number: 4665184Abstract: Novel bifunctional molecules having a DNA intercalator or DNA groove binder linked to ethylene diamine tetraacetic acid such as compounds having the formula: ##STR1## wherein R is methyl or ethyl. Also, the method of cleaving DNA by contact with one of the above-identified molecules in the presence of ferrous ion and oxygen.The process of preparing said molecules by the reaction of P-carboxy methidium halide, p-carboxy ethidium halide, or other DNA intercalator or DNA groove binder with 1-3-diaminopropane followed by condensation with ethylenediamine tetraacetic acid.Distamycin-EDTA.Fe(II)(DE.FE(II)) contains EDTA attached to the amino terminus of the groove binder tripeptide (tris-N-methylpyrrolecarboxamide). DE.Fe(II) cleaves DNA contiguous to a five base pair A+T rich sequence. This is a novel and unique molecule and superior in sequence specificity to the naturally occurring antitumor compound used in man, bleomycin which cleaves DNA at a two base pair recognition site.
