STIM1-TFR1-IN-1 is an inhibitor of the STIM1-transferrin receptor 1 (TFR1) protein complex, exhibiting a binding affinity (Kd) of 2.18 μM to the STIM1-CD protein. This compound effectively disrupts the STIM1-TFR1 interaction, thereby decreasing TFR1-mediated iron uptake while inhibiting ferroptosis, lipid peroxidation, and reactive oxygen species (ROS) production. STIM1-TFR1-IN-1 also enhances glutathione peroxidase 4 (GPX4) activity and improves the glutathione/oxidized glutathione ratio, promoting neuroprotective effects and mitigating brain injury. This reagent is particularly relevant for studies focusing on intracerebral hemorrhage.
