    • Inhibitor of necroptosis, by blocking mixed lineage kinase domain-like protein (MLKL), a key substrate of receptor-interacting serine-threonine kinase 3 (RIP3). Shown to prevent the MLKL-RIP1-RIP3 necrosome complex from interacting with downstream necrosis effectors.
    • Potent inhibitor of gasdermin D that works well for mice studies. It binds directly to gasdermin D and inhibits the oligomerization of the N-terminus and therefore the pore formation and pyroptosis.
    • Displayed neuroprotective effects after ischemic brain injury, prevented cystine-starvation-induced necroptosis and ferroptosis in human triple negative breast cancer cells and rescued cells from TLR3 ligand-induced death.
