Molecular engineering of G-quadruplex ligands based on solvent effect of polyethylene glycol
Nucleic Acids Res 2012 Sep 1;40(17):8711-20.PMID:22735707DOI:10.1093/nar/gks578.
Because various non-parallel G-quadruplexes of human telomeric sequences in K+ solution can be converted to a parallel G-quadruplex by adding polyethylene glycol (PEG) as a co-solvent, we have taken advantage of this property of PEG to study the covalent attachment of a PEG unit to a G-quadruplex ligand, 3,6-bis(1-methyl-4-vinylpyridinium) carbazole diiodide (BMVC). The hybrid ligand with the PEG unit, BMVC-8C3O or BMVC-6C2O by substituting either the tetraethylene glycol or the triethylene glycol terminated with a methyl-piperidinium cation in N-9 position of BMVC, not only induces structural change from different non-parallel G-quadruplexes to a parallel G-quadruplex but also increases the melting temperature of human telomeres in K+ solution by more than 45°C. In addition, our ligand work provides further confidence that the local water structure plays the key to induce conformational change of human telomere.
A novel transition pathway of ligand-induced topological conversion from hybrid forms to parallel forms of human telomeric G-quadruplexes
Nucleic Acids Res 2016 May 5;44(8):3958-68.PMID:26975658DOI:10.1093/nar/gkw145.
The folding topology of DNA G-quadruplexes (G4s) depends not only on their nucleotide sequences but also on environmental factors and/or ligand binding. Here, a G4 ligand, 3,6-bis(1-methyl-4-vinylpyridium iodide)-9-(1-(1-methyl-piperidinium iodide)-3,6,9-trioxaundecane) carbazole (BMVC-8C3O), can induce topological conversion of non-parallel to parallel forms in human telomeric DNA G4s. Nuclear magnetic resonance (NMR) spectroscopy with hydrogen-deuterium exchange (HDX) reveals the presence of persistent imino proton signals corresponding to the central G-quartet during topological conversion of Tel23 and Tel25 G4s from hybrid to parallel forms, implying that the transition pathway mainly involves local rearrangements. In contrast, rapid HDX was observed during the transition of 22-CTA G4 from an anti-parallel form to a parallel form, resulting in complete disappearance of all the imino proton signals, suggesting the involvement of substantial unfolding events associated with the topological transition. Site-specific imino proton NMR assignments of Tel23 G4 enable determination of the interconversion rates of individual guanine bases and detection of the presence of intermediate states. Since the rate of ligand binding is much higher than the rate of ligand-induced topological conversion, a three-state kinetic model was evoked to establish the associated energy diagram for the topological conversion of Tel23 G4 induced by BMVC-8C3O.
