Area of Science:

• Genomics
• Molecular Biology
• Drug Discovery

Background:

• G-quadruplexes are unique secondary structures in guanine-rich genomic regions.
• These structures play critical roles in DNA replication, repair, transcription, and translation, particularly concerning oncogenes.
• Dysregulation of G-quadruplexes is implicated in cancer development.

Purpose of the Study:

• To review the potential of G-quadruplex ligands as anti-tumor therapeutics.
• To explore the feasibility of targeting G-quadruplexes from fundamental principles to practical applications.
• To highlight the significance of helicase interactions with G-quadruplexes in drug design.

Main Methods:

• Literature review focusing on G-quadruplex structure, function, and ligand development.
• Analysis of small molecules designed to interact with G-quadruplexes.
• Examination of the role of G-quadruplex-related proteins, especially helicases, in anti-cancer drug strategies.

Main Results:

• Various small molecules targeting G-quadruplexes have been identified as potential anti-cancer agents.
• Ligands can act by directly binding to G-quadruplexes or by interfering with protein-G-quadruplex interactions.
• Helicases represent a well-defined target class for G-quadruplex-mediated anti-cancer therapies.

Conclusions:

• G-quadruplex ligands represent a promising avenue for novel anti-tumor drug development.
• Understanding the interplay between G-quadruplexes and proteins like helicases is crucial for effective drug design.
• Targeting G-quadruplexes offers a viable strategy for cancer treatment.
