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

open access: yesPharmaceuticals, 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

Formation of a unique cluster of G-quadruplex structures in the HIV-1 Nef coding region: implications for antiviral activity. [PDF]

open access: yesPLoS ONE, 2013
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]

open access: goldChemistryOpen, 2020
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]

open access: yesNature Genetics, 2016
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

Developing Novel G-Quadruplex Ligands: from Interaction with Nucleic Acids to Interfering with Nucleic Acid–Protein Interaction

open access: yesMolecules, 2019
G-quadruplex is a special secondary structure of nucleic acids in guanine-rich sequences of genome. G-quadruplexes have been proved to be involved in the regulation of replication, DNA damage repair, and transcription and translation of oncogenes or ...

Genomic G-quadruplex folding triggers a cytokine-mediated inflammatory feedback loop to aggravate inflammatory diseases

open access: yesiScience, 2022
Summary: DNA G-quadruplex is a non-canonical secondary structure that could epigenetically regulate gene expression. To investigate the regulating role of G-quadruplex, we devised an integrating method to perform the algorithm profiling and genome-wide ...

G-Quadruplexes in Human Telomere: Structures, Properties, and Applications

open access: yesMolecules, 2023
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 ...

Evaluating RHAU140-CFP molecule for specific recognition of parallel DNA G-Quadruplex by the fluorescence spectrophotometer

open access: yesTạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Kỹ thuật và Công nghệ, 2023
Determination of G-quadruplex formation in DNA is required for the design of small molecules (drugs) targeting G-quadruplex. In previous studies, we used the fluorescent protein RHAU53-CFP capable of recognizing parallel G-quadruplex structures through a
