MLKL-IN-1, a covalent inhibitor of MLKL, has a dissociation constant (Kd) of 50 μM.

MLKL-IN-5 is a potent small molecule inhibitor of MLKL. By specifically targeting MLKL, it prevents its phosphorylation by RIPK3 and subsequent oligomerization, thereby blocking the transmission of the necroptosis signaling pathway. It is an important pharmacological tool molecule for studying the pathological mechanisms of necroptosis in various inflammatory diseases, neurodegenerative diseases, and cancer.

MLKL-IN-6 (compound P28) is a mixed lineage kinase inhibitor that specifically targets the Mixed Lineage Kinase domain-like (MLKL) protein.

TC13172 is a potent and covalent inhibitor that specifically targets the mixed lineage kinase domain-like protein (MLKL), exhibiting significant selectivity for MLKL over the closely related receptor-interacting serine/threonine kinase 1 (RIPK1) and RIPK3 at a concentration of 10 µM.TC13172 effectively inhibits necroptosis induced by the TSZ combination (TNF-α, a Smac mimetic, and Z-VAD-FMK) in HT-29 cells with a EC50 of 2 nM and, at 100 nM, blocks TSZ-induced oligomerization and plasma membrane translocation of MLKL.

NecroX-2 is a cell-permeable necrosis inhibitor with antioxidant properties. NecroX-2 selectively suppresses necrotic cell death triggered by oxidative stress. NecroX-2 does not confer protection against apoptosis induced by staurosporine or etoposide but shows protective effects under conditions such as cold shock, hypoxia, and oxidative stress in vitro.

MBA-m1 is an MLKL inhibitor that suppresses necroptosis in Mlkl−/−NIH-3T3 cells. Additionally, MBA-m1 alleviates disease conditions in mouse models of dermatitis and abdominal aortic aneurysm induced by MLKL.
