High-Resolution Three-Dimensional NMR Structure Of The KRAS Proto-Oncogene Promoter Reveals Key Features Of A G-Quadruplex Involved In Transcriptional Regulation [PDF]

, 2017
Non-canonical base pairing within guanine-rich DNA and RNA sequences can produce G-quartets, whose stacking leads to the formation of a G-quadruplex (G4).

Control of the polyamine biosynthesis pathway by G2-quadruplexes

eLife, 2018
G-quadruplexes are naturally-occurring structures found in RNAs and DNAs. Regular RNA G-quadruplexes are highly stable due to stacked planar arrangements connected by short loops.

Conserved presence of G-quadruplex forming sequences in the Long Terminal Repeat Promoter of Lentiviruses [PDF]

, 2017
G-quadruplexes (G4s) are secondary structures of nucleic acids that epigenetically regulate cellular processes. In the human immunodeficiency lentivirus 1 (HIV-1), dynamic G4s are located in the unique viral LTR promoter.

1,1’,1’’,1’’’-[Porphyrin-5,10,15,20-tetrayltetrakis(3,1-phenylenemethylene)]tetraquinolinium Tetrabromide

Molbank, 2010
Cationic porphyrins interact strongly with guanine quadruplex DNA (G-quadruplex). We herein report the preparation of a cationic porphyrin bearing quinolinium side arms, 1,1’,1’’,1’’’-[porphyrin-5,10,15,20-tetrayltetrakis(3,1-phenylenemethylene)]­tetra ...

Fluorescent Detection of the Ubiquitous Bacterial Messenger 3′,5′ Cyclic Diguanylic Acid by Using a Small Aromatic Molecule

Frontiers in Microbiology, 2020
3′,5′ Cyclic diguanylic acid (c-di-GMP) has been shown to play a central role in the regulation of bacterial physiological processes such as biofilm formation and virulence production, and is regarded as a potential target for the development of anti ...

Ligand selectivity in stabilising tandem parallel folded G-quadruplex motifs in human telomeric DNA sequences [PDF]

, 2014
Biophysical studies of ligand interactions with three human telomeric repeat sequences (d(AGGG(TTAGGG)n, n = 3, 7 and 11)) show that an oxazole-based ‘click’ ligand, which induces parallel folded quadruplexes, preferentially stabilises longer telomeric ...

Structured Waters Mediate Small Molecule Binding to G-Quadruplex Nucleic Acids

Pharmaceuticals, 2021
The role of G-quadruplexes in human cancers is increasingly well-defined. Accordingly, G-quadruplexes can be suitable drug targets and many small molecules have been identified to date as G-quadruplex binders, some using computer-based design methods and

Rudimentary G-Quadruplex-Based Telomere Capping In Saccharomyces Cerevisiae [PDF]

, 2011
Telomere capping conceals chromosome ends from exonucleases and checkpoints, but the full range of capping mechanisms is not well defined. Telomeres have the potential to form G-quadruplex (G4) DNA, although evidence for telomere G4 DNA function in vivo ...

New trends for metal complexes with anticancer activity [PDF]

, 2008
Medicinal inorganic chemistry can exploit the unique properties of metal ions for the design of new drugs. This has, for instance, led to the clinical application of chemotherapeutic agents for cancer treatment, such as cisplatin. The use of cisplatin is,
