Discovery of new G-quadruplex binding chemotypes

Area of Science:

• Medicinal Chemistry
• Molecular Biology
• Drug Discovery

Background:

• G-quadruplexes are non-canonical DNA secondary structures implicated in various cellular processes.
• Targeting G-quadruplexes is a promising strategy for developing novel therapeutics.

Purpose of the Study:

• To report the discovery of a novel class of non-macrocyclic, low molecular weight compounds.
• To evaluate the G-quadruplex stabilizing properties and anti-proliferative activity of these novel compounds.

Main Methods:

• Synthesis of novel furan-based compounds.
• Assessment of G-quadruplex stabilization using biophysical methods.
• Evaluation of in vitro anti-proliferative activity against cancer cell lines.

Main Results:

• Identification of a novel chemotype with a furan core.
• Compounds demonstrated high G-quadruplex stabilization and selectivity.
• Lead compounds exhibited potent in vitro anti-proliferative activity.

Conclusions:

• The novel non-macrocyclic compounds represent a promising new class of G-quadruplex stabilizers.
• These findings support further development of these compounds as potential anti-cancer agents.
