DNA-binding hairpin pyrrole-imidazole polyamides with γ-aminobutyric acid as a turn-forming residue tolerate A · T or T · A base pairs under the turn. U-pins - polyamides with a different turn - have been synthesized and their DNA binding properties were studied. The two turn-forming residues are connected via the ring nitrogens using variable length aliphatic linkers ((CH2)n, n = 3-6). Through optimization of the linker length and the substituents at the 2-position of the pyrrole residue on the U-turn, polyamides with G · C/C · G tolerant turns could be found, which bind to DNA in a predictable manner.
