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

Formation of a unique cluster of G-quadruplex structures in the HIV-1 Nef coding region: implications for antiviral activity. [PDF]
G-quadruplexes are tetraplex structures of nucleic acids that can form in G-rich sequences. Their presence and functional role have been established in telomeres, oncogene promoters and coding regions of the human chromosome.

Kinetic Target‐Guided Synthesis of Small‐Molecule G‐Quadruplex Stabilizers [PDF]
The formation of a G‐quadruplex motif in the promoter region of the c‐MYC protooncogene prevents its expression. Accordingly, G‐quadruplex stabilization by a suitable ligand may be a viable approach for anticancer therapy.

G-quadruplex structures mark human regulatory chromatin [PDF]
G-quadruplex (G4) structural motifs have been linked to transcription, replication and genome instability and are implicated in cancer and other diseases. However, it is crucial to demonstrate the bona fide formation of G4 structures within an endogenous

The Presence and Localization of G-Quadruplex Forming Sequences in the Domain of Bacteria
The role of local DNA structures in the regulation of basic cellular processes is an emerging field of research. Amongst local non-B DNA structures, the significance of G-quadruplexes was demonstrated in the last decade, and their presence and functional

G-Quadruplexes in Human Telomere: Structures, Properties, and Applications
G-quadruplexes, intricate four-stranded structures composed of G-tetrads formed by four guanine bases, are prevalent in both DNA and RNA. Notably, these structures play pivotal roles in human telomeres, contributing to essential cellular functions ...
