Fluorescence-based duplex–quadruplex competition test to screen for telomerase RNA quadruplex ligands
RNA and DNA guanine-rich sequences can adopt unusual structures called Guanine quadruplexes (G4). A quadruplex-prone RNA sequence is present at the 5'-end of the 451-nt-long RNA component of telomerase, hTERC. As this quadruplex may interfere with P1 helix formation, a key structural element for this RNA, we are seeking molecules that would alter this RNA duplex-quadruplex equilibrium. In this ...
متن کاملQuadruplex ligands may act as molecular chaperones for tetramolecular quadruplex formation
G-quadruplexes are a family of four-stranded DNA structures, stabilized by G-quartets, that form in the presence of monovalent cations. Efforts are currently being made to identify ligands that selectively bind to G-quadruplex motifs as these compounds may interfere with the telomere structure, telomere elongation/replication and proliferation of cancer cells. The kinetics of quadruplex-ligands...
متن کاملMolecular docking based screening of triterpenoids as potential G-quadruplex stabilizing ligands with anti-cancer activity
Triterpenoids isolated from Ganoderma lucidum (GLTs) exhibit a broad spectrum of anti-cancer properties, including anti-proliferative, anti-metastatic and anti-angiogenic activities. Current research studies revealed the role by GLTs in inducing apoptosis and suppression of telomerase activity of cancer cells with much lower toxicity to healthy cells. Compounds selectively binding and stabilizi...
متن کاملA new method for the study of G-quadruplex ligands.
A new method for the study of G-quadruplex ligands was developed, in which the interaction of G-quadruplexes with ligands can be judged by the naked eye, eliminating the need for any expensive machines.
متن کاملG-quadruplex ligands exhibit differential G-tetrad selectivity.
A rapid and simple equilibrium-binding assay mediated by ligand-induced fluorescence quenching of fluorophore-labelled G-quadruplex (G4) structures enabled quantitative interrogation of mutually exclusive ligand binding interactions at opposed G-tetrads. This technique revealed that the ligands TmPyP4, PhenDC3, and PDS have differential chemotype-specific binding preferences for individual G-te...
