    • Competition FRET experiments were performed as described above for the G-quadruplex experiment but with addition of varying concentrations of double strand DNA from calf thymus, c.t. dsDNA (Sigma-Aldrich, UK) (Moorhouse, A. D.; Santos, A. M.; Gunaratnam, M.; Moore, M.; Neidle, S.; Moses, J. E. J. Am. Chem. Soc. 2006, 128, 15972). The ct dsDNA has a length of about 200 bp and was obtained by sonication.

    • 32P-radiolabelled TS (0.16 μM final concentration) and 1 μl/sample of Primer Mix, 2U Taq DNA polymerase (Taq DNA polymerase/HotMaster™) were added in each sample. 30 PCR cycles were performed (94°/10′, 92°/30″, 54°/30″, 72°/5′30″). Finally, the samples were loaded on a native 12% polyacrylamide gel. Samples without the compound and without the cell-extract were used as references. A 36 bp oligonucleotide (IS) was used as internal standard to evaluate PCR amplification efficiency.

    • 13 The concentrations of DNAs started at 400 μM so to have a DNA/drug molar ratio R equal to 20 and then were decreased up to 0.5 μM, by substituting a volume of drug/DNA solutions with an equal volume of 20 μM drug solution. Absorption spectra were performed with a Varian Cary 50 spectrophotometer, using a cell with a 1 cm path length. Each spectrum was acquired after the sample has been equilibrated for at least 4 min.

    • 16 CD spectra were recorded on JASCO 710 dichrograph using a 1.0 cm path length cell. Each spectrum was acquired after the sample had been equilibrated for at least 4 min. For each sample, the scan of the buffer alone was subtracted from the average scan. The reported spectrum was averaged from at least four different scans.
