Guanine-rich nucleic acid sequences can adopt G-quadruplex structures stabilized by layers of four Hoogsteen-paired guanine residues.
Quadruplex-prone sequences are found in many regions of human genome and in the telomeres of all eukaryotic organisms.
Since small molecules that target G-quadruplexes have been found to be effective telomerase inhibitors, the identification of new specific ligands for G-quadruplexes is emerging as a promising approach to develop new anticancer drugs.
Distamycin A is known to bind to AT-rich sequences of duplex DNA, but it has recently been shown to interact also with G-quadruplexes.
Here, isothermal titration calorimetry (ITC) and NMR techniques have been employed to characterize the interaction between a dicationic derivative of distamycin A (compound 1) and the [d(TGGGGT)]4 quadruplex.
Additionally, to compare the binding behaviour of netropsin and compound 1 to the same target, a calometric study of the interaction between netropsin and [d(TGGGGT)]4 has been performed.
Experiments show that netropsin and compound 1 are able to bind to [d(TGGGGT)]4 with good affinity and comparable thermodynamic profiles.
In both cases the interactions are entropically driven processes with a small favourable enthalpic contribution.
Interestingly, the structural modifications of compound 1 decrease the affinity of the ligand toward the duplex, enhancing the selectivity.
