Abstract
Abnormal and dysregulated cell death plays important roles in organ injury. Necroptosis and ferroptosis are two distinct types of regulated cell death that can trigger inflammation and are involved in organ injury. The inhibition of necroptosis and ferroptosis is proposed to be beneficial for treating multiple pathological conditions. To find out necroptosis and ferroptosis inhibitors, we used a small-molecule compound library for screening and identified a clinically advanced compound, Dovitinib (Dov), as a potent dual inhibitor of necroptosis and ferroptosis. Dov inhibited tumor necrosis factor (TNF)-induced necroptosis by regulating receptor-interacting protein kinase 1 (RIPK1) and alleviated TNF-mediated systemic inflammatory response syndrome. Additionally, Dov inhibited ferroptosis by regulating the NRF2/HMOX1 axis and lipid peroxidation and protected against concanavalin A-induced acute liver injury. Thus, our work revealed that Dov is a dual inhibitor of necroptosis and ferroptosis and provides a potential therapeutic drug or combination approach for treating necroptosis- and ferroptosis-related diseases.
期刊介绍:
ACS Chemical Biology provides an international forum for the rapid communication of research that broadly embraces the interface between chemistry and biology.
The journal also serves as a forum to facilitate the communication between biologists and chemists that will translate into new research opportunities and discoveries. Results will be published in which molecular reasoning has been used to probe questions through in vitro investigations, cell biological methods, or organismic studies.
We welcome mechanistic studies on proteins, nucleic acids, sugars, lipids, and nonbiological polymers. The journal serves a large scientific community, exploring cellular function from both chemical and biological perspectives. It is understood that submitted work is based upon original results and has not been published previously.
