Targeting the DNA cleavage activity of copper phenanthroline and clip-phen to A.T tracts via linkage to a poly-N-methylpyrrole.
To target DNA A.T tracts, a three-ring polyamide containing an N-methylpyrrole amino acid has been linked, on solid support, to carboxylic derivatives of phenanthroline and dimers of phenanthroline: 2-Clip-Phen, 3-Clip-Phen, or 2-Clip-Phen containing a long tether. After metalation by CuCl(2), the DNA cleavage activities of the different conjugates were compared on a restriction fragment. Cleavage patterns showed that the polyamide moiety of conjugates directs the cleavage activity in the vicinity of A.T tracts but the precise cleavage selectivity of these conjugates was dependent on the type of phenanthroline residue linked to the poly-N-methylpyrrole entity.
