MLKL-IN-4 (compound 56) is a potentMLKL(Mixed lineage kinase domain-like protein) inhibitor. MLKL-IN-4 inhibitsnecroptosisin HT-29 cells and acts downstream of MLKL phosphorylation, withEC₅₀of 82 nM^[1].

MLKL-IN-4 (compound 56) (10 μM) slightly inhibits RIPK1, does not affect the phosphorylation status of RIPK1 and MLKL^[1].
MLKL-IN-4 (1 μM, 24 h) inhibits the translocation of MLKL to cell membranes in HT-29 cells^[1].

MLKL-IN-4 (compound 56) shows T1/2 over 48 h and more than 150-fold lower reaction rates with glutathione (GSH), which potentially decreased their off-target effects and cell toxicity^[1].
