Patent ID: 7452730

Claim:
A DNA-binding polymer comprising: a first terminus, an oligomeric backbone optionally containing a linking element, and a second terminus; wherein: said first terminus is an optionally substituted thiophene-containing moiety; said oligomeric backbone comprises a plurality of optionally substituted monomer elements; said second terminus is selected from the group consisting of optionally substituted N-methylpyrrole, optionally substituted N-methylimidazole, and optionally substituted benzimidazole moiety; said DNA-binding polymer is effective to bind to a double-stranded DNA sequence having a number of DNA base pairs in the range (n/2) to (2n) where n is the number of monomer elements in said DNA-binding polymer; and said first terminus and said second terminus of said DNA-binding polymer are effective in combination to bind to a T•A DNA base pair.
