Recent progress and future potential for metal complexes as anticancer drugs targeting G-quadruplex DNA

Area of Science:

• Medicinal Chemistry
• Biochemistry
• Oncology

Background:

• Cisplatin analogs are effective chemotherapy but cause significant toxicities and resistance.
• G-quadruplexes are crucial in cancer and stabilizing them inhibits oncogenes.
• Metal complexes show potential as selective anticancer agents targeting G-quadruplex DNA.

Purpose of the Study:

• To review recent advancements in metal complexes as anticancer drugs targeting G-quadruplex DNA.
• To discuss the potential of these novel agents in medical applications.
• To explore various metal complexes including Ruthenium, Nickel, Zinc, Manganese, Copper, and Palladium/Platinum.

Main Methods:

• Literature review of metal complexes interacting with G-quadruplex DNA.
• Analysis of studies on the anticancer activity of these complexes.
• Categorization of metal complexes based on the metal ion involved.

Main Results:

• Metal complexes can strongly and selectively bind to G-quadruplex DNA.
• Several metal complexes demonstrate significant anticancer activity.
• The review covers complexes of Ruthenium(II), Nickel(II), Zinc(II), Manganese(III), Copper(II), and Palladium(II)/Platinum(II).

Conclusions:

• Metal complexes represent a promising avenue for developing new anticancer therapies.
• Targeting G-quadruplex DNA with metal complexes offers a strategy to overcome cisplatin resistance and toxicity.
• Further research into metal complexes holds significant potential for future cancer treatment.
