Research progress on GPX4 targeted compounds

Area of Science:

• Biochemistry
• Oncology
• Pharmacology

Background:

• The System Xc-/glutathione/GPX4 pathway is crucial for cell survival.
• GPX4 is a key regulator of ferroptosis, a form of programmed cell death.
• Targeting GPX4 offers a novel strategy for cancer therapy.

Purpose of the Study:

• To review compounds that directly target the GPX4 protein.
• To explore inhibitors, activators, and degraders of GPX4.
• To discuss combination therapies involving GPX4 targeting agents.

Main Methods:

• Literature search for compounds targeting GPX4.
• Categorization of compounds based on their mechanism of action (inhibitors, activators, degraders).
• Analysis of current research on GPX4-targeting agents and combination therapies.

Main Results:

• Several classes of compounds directly targeting GPX4 have been identified.
• These include small molecule inhibitors, activators, and novel degraders (small molecule and chimeric).
• Combination therapies show promise in enhancing anti-tumor effects.

Conclusions:

• Direct targeting of GPX4 is a viable strategy for inducing ferroptosis in cancer cells.
• Further research into GPX4-targeting compounds and combination therapies is warranted.
• This approach holds potential for developing new cancer treatments.
