Ferroptosis-related small-molecule compounds in cancer therapy: Strategies and applications

Area of Science:

• Biochemistry
• Cell Biology
• Oncology

Background:

• Ferroptosis is a regulated cell death pathway characterized by iron-dependent lipid peroxidation.
• Research in ferroptosis has rapidly expanded since its definition in 2012.
• Small-molecule drugs inducing ferroptosis show potential in reducing tumor growth.

Purpose of the Study:

• To review the interplay between ferroptosis and cancer signaling pathways.
• To summarize small-molecule compounds that induce ferroptosis in cancer cells.
• To highlight the future development of ferroptosis-based anticancer therapeutics.

Main Methods:

• Literature review of ferroptosis research.
• Analysis of small-molecule compounds targeting ferroptosis.
• Discussion of ferroptosis's role in tumor biology.

Main Results:

• Sorafenib induces ferroptosis in hepatocellular carcinoma cell lines.
• Sulfasalazine inhibits cancer cell proliferation by targeting system Xc- mediated cystine transport.
• Various small molecules demonstrate ferroptosis-inducing capabilities.

Conclusions:

• Ferroptosis is a critical mechanism in cancer cell death.
• Understanding ferroptosis crosstalk with signaling pathways is key for drug development.
• Ferroptosis inducers represent a promising avenue for novel anticancer drug discovery.
