Parallel tetramolecular quadruplexes may be formed with short oligodeoxynucleotides bearing a block of three or more guanines. We analyze the properties of sequence variants of parallel quadruplexes in which each guanine of the central block was systematically substituted with a different base. Twelve types of substitutions were assessed in more than 100 different sequences. We conducted a comparative kinetic analysis of all tetramers. Electrospray mass spectrometry was used to count the number of inner cations, which is an indicator of the number of effective tetrads. In general, the presence of a single substitution has a strong deleterious impact on quadruplex stability, resulting in reduced quadruplex lifetime/ thermal stability and in decreased association rate constants. We demonstrate extremely large differences in the association rate constants of these quadruplexes depending on modification position and type. These results demonstrate that most guanine substitutions are deleterious to tetramolecular quadruplex structure. Despite the presence of well- defined non- guanine base quartets in a number of NMR and X- ray structures, our data suggest that most non- guanine quartets do not participate favorably in structural stability, and that these quartets are formed only by virtue of the docking platform provided by neighboring G- quartets. Two notable exceptions were found with 8- bromoguanine ( X) and 6- methyl- isoxanthopterin ( P) substitutions, which accelerate quadruplex formation by a factor of 10 when present at the 50 end. The thermodynamic and kinetic data compiled here are highly valuable for the design of DNA quadruplex assemblies with tunable association/ dissociation properties. [less ▲]

A promising approach for anticancer strategies is the stabilization of telomeric DNA into a G-quadruplex structure. To explore the intrinsic stabilization of folded G-quadruplexes, we combined electrospray ionization mass spectrometry, ion mobility spectrometry, and molecular modeling studies to study different DNA sequences known to form quadruplexes. Two telomeric DNA sequences of different lengths and two DNA sequences derived from the NHE III1 region of the c-myc oncogene (Pu22 and Pu27) were studied. NH4+ and the ligands PIPER, TMPyP4, and the three quinacridines MMQ1, MMQ3, and BOQ1 were complexed with the DNA sequences to determine their effect on the stability of the G-quadruplexes. Our results demonstrate that G-quadruplex intramolecular folds are stabilized by NH4+ cations and the ligands listed. Furthermore, the ligands can be classified according to their ability to stabilize the quadruplexes and end stacking is shown to be the dominant mode for ligand attachment. In all cases our solvent-free experimental observations and theoretical modeling reveal structures that are highly relevant to the solution-phase structures. [less ▲]
