Polyphenols bind G4-Quadruplex structures and act as epigenetic modifiers with anti-cancer effects.

Area of Science:

• Biochemistry
• Molecular Biology
• Pharmacology

Background:

• G-quadruplexes (G4s) are non-canonical nucleic acid structures found in DNA and RNA.
• G4s are present in oncogenic promoters and telomeres, making them key targets for anticancer drug design.
• G4s also function as epigenetic modulators, influencing gene expression.

Purpose of the Study:

• To review natural compounds, particularly dietary polyphenols, as G-quadruplex (G4) targeted ligands.
• To explore the structural chemistry of polyphenols for G4 ligand potential.
• To investigate polyphenols' mechanisms in regulating epigenetic machinery through G4 binding for cancer therapy.

Main Methods:

• Literature review focusing on natural compounds and G-quadruplexes.
• Analysis of dietary polyphenols' structural features relevant to G4 binding.
• Exploration of G4-binding mechanisms in epigenetic regulation.

Main Results:

• Natural products, especially dietary polyphenols, are investigated as G4 ligands.
• Polyphenols possess structural characteristics suitable for G4 targeting.
• Polyphenols show potential in modulating epigenetic processes via G4 interaction.

Conclusions:

• Dietary polyphenols represent a promising class of natural compounds for G4-targeted anticancer drug development.
• Understanding polyphenol-G4 interactions can lead to novel epigenetic therapies.
• Further research into polyphenols could yield safe and effective anticancer agents.
