Abstract
Ferroptosis is a newly identified form of regulated, non-apoptotic cell death caused by iron-dependent phospholipid peroxidation. Glutathione peroxidase 4 (GPX4) inactivation-induced ferroptosis is an efficient antitumor treatment. Currently, several GPX4 inhibitors have been identified. However, these inhibitors exhibit low selectivity and poor pharmacokinetic properties that preclude their clinical use. Targeted protein degradation (TPD) is an efficient strategy for discovering drugs and has unique advantages over target protein inhibition. Given GPX4's antitumor effects and the potential of TPD, researchers have explored GPX4-targeting TPDs, which outperform conventional inhibitors in several aspects, such as increased selectivity, strong anti-proliferative effects, overcoming drug resistance, and enhancing drug-like properties. In this review, we comprehensively summarize the progress in GPX4-targeting TPDs. In addition, we reviewed the changes and challenges related to the development of GPX4-targeting TPDs for cancer therapy.
期刊介绍:
Bioorganic & Medicinal Chemistry provides an international forum for the publication of full original research papers and critical reviews on molecular interactions in key biological targets such as receptors, channels, enzymes, nucleotides, lipids and saccharides.
The aim of the journal is to promote a better understanding at the molecular level of life processes, and living organisms, as well as the interaction of these with chemical agents. A special feature will be that colour illustrations will be reproduced at no charge to the author, provided that the Editor agrees that colour is essential to the information content of the illustration in question.
