Visualization of G-quadruplexes by using a BODIPY-labeled macrocyclic heptaoxazole.

چکیده
A BODIPY-labeled macrocyclic heptaoxazole, L1BOD-7OTD, was developed as a fluorescent ligand for G-quadruplexes. The results of the study show that L1BOD-7OTD both selectively induces the formation of intramolecular G-quadruplexes from some G-quadruplex forming oligonucleotides (GFOs). In addition, the labelled macrocyclic heptaozaxole strongly binds to and stabilizes intramolecular G-quadruplexes. Moreover, this substance can be used to directly visualize the G-quadruplexes in the form of green fluorescence. Finally, the possibility that G-quadruplexes form in the cells was demonstrated by using of L1BOD-7OTD.

Targeting DNA G-Quadruplexes with Helical Small Molecules
We previously identified quinoline-based oligoamide helical foldamers and a trimeric macrocycle as selective ligands of DNA quadruplexes. Their helical structures might permit targeting of the backbone loops and grooves of G-quadruplexes instead of the G-tetrads. Given the vast array of morphologies G-quadruplex structures can adopt, this might be a way to achieve sequence selective binding. He...
متن کاملSynthesis of Macrocyclic Hexaoxazole (6OTD) Dimers, Containing Guanidine and Amine Functionalized Side Chains, and an Evaluation of Their Telomeric G4 Stabilizing Properties
Structure-activity relationship studies were carried out on macrocyclic hexaoxazole (6OTD) dimers, whose core structure stabilizes telomeric G-quadruplexes (G4). Two new 6OTD dimers having side chain amine and guanidine functional groups were synthesized and evaluated for their stabilizing ability against a telomeric G4 DNA sequence. The results show that the 6OTD dimers interact with the DNA t...

متن کامل“One Ring to Bind Them All”—Part I: The Efficiency of the Macrocyclic Scaffold for G-Quadruplex DNA Recognition
Macrocyclic scaffolds are particularly attractive for designing selective G-quadruplex ligands essentially because, on one hand, they show a poor affinity for the "standard" B-DNA conformation and, on the other hand, they fit nicely with the external G-quartets of quadruplexes. Stimulated by the pioneering studies on the cationic porphyrin TMPyP4 and the natural product telomestatin, follow-up ...
متن کاملSingle-cell analysis of phosphoinositide 3-kinase and phosphatase and tensin homolog activation.
A single-cell assay was developed to measure the activation of phosphoinositide 3-kinase (PI3K) using microanalytical chemical separations and a fluorescently labeled lipid substrate. Phosphatidyl-inositol 4,5 bisphosphate labeled on its acyl chain with Bodipy fluorescein (Bodipy Fl PIP(2)) was utilized as a substrate for both in vitro and cell-based assays. Detection limits for the substrate a...
