Overview

Information

iFSP1 iFSP1 is a potent, selective and glutathione-independent inhibitor of ferroptosis suppressor protein 1 (FSP1/AIFM2) with EC50 of 103 nM. iFSP1 selectively induces ferroptosis in GPX4-knockout Pfa1 and HT1080 cells that overexpresses FSP1.

Targets

FSP1/AIFM2 (Cell-free assay) 103 nM(EC50)

In vitro

iFSP1 selectively induces ferroptosis in GPX4-knockout Pfa1 and HT1080 cells that overexpressed FSP1. FSP1 is expressed in most tumour cell lines, and iFSP1 treatment robustly sensitizes these cells to RSL3-induced ferroptosis.
