    • 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. EDTA-distamycin-Fe(II)(ED.Fe(III)) contains EDTA attached to the carboxy terminus of the groove binder tripeptide, tris-N-methylpyrrolecarboxamide. ED.Fe(II) cleaves DNA contiguous to a five base pair A+T rich sequence. Penta-N-methylpyrrolecarboxamide-EDTA.Fe(II)(P5E.Fe(II)) cleaves DNA on opposite strand at the six base pair recognition level in a catalytic reaction. This is the first designed synthetic molecule that approximates the double strand sequence specific cleavage of DNA(4-6 bp recognition level) by the natural substance restriction enzymes, tools which make possible recombinant DNA manipulations. P5E.Fe(II) cuts DNA at sequences not available by the naturally occurring restriction enzymes.The dimers, bis(EDTA-distamycin.Fe(II) and EDTA-bisdistamycin.Fe(II) which double strand cleave DNA at the eight base pair recognition level (A+T rich).

    • Small molecule polyamides that specifically bind with subnanomolar affinity to any predetermined sequence in the human genome with potential use in molecular biology and human medicine are described. Further, the designed compounds which target the minor groove of B-form double helical DNA offer a general approach for the control of gene-expression. Simple rules are disclosed which provide for rational control of the DNA-binding sequence specificity of synthetic polyamides containing N-methylpyrrole and N-methylimidazole amino acids. A series of molecular templates for polyamide design are disclosed which provide for small molecules which recognize predetermined DNA sequences with affinities and specificities comparable to sequence-specific DNA-binding proteins such as transcription factors. These design rule are applied to provide a polyamide for specific targeting of a predetermined 7 base pair sequence from a conserved HIV gene promoter at subnanomolar concentration. The pyrrole-imidazole polyamides described herein represent the only class of designed small molecules to date that can bind any predetermined sequence of double helical DNA.
