Mixed Lineage Kinase

MLKs

Mixed lineage kinases (MLKs) are mitogen activated protein kinase kinase kinases (MAPKKKs) with features of both serine-threonine and tyrosine kinases that regulate the c-Jun N-terminal kinase (JNK) mitogen activated protein kinase (MAPK) signaling cascade, and also regulate p38 and extracellular signal-regulated kinase (ERK).

MLK3 (MAP3K11) is the most widely expressed MLK family member, and is expressed in neurons (as well as other cell types). At the cellular level, MLK3 is activated by stress, including reactive oxygen species, ceramide, and TNFα. At the molecular level, it is activated by Cdc42 and Rac, which interact with MLK3, and can cause it to dimerize via a leucine zipper interface, resulting in autophosphorylation and enzyme activation.

    (E/Z)-Necrosulfonamide
    Inhibitor
    (E/Z)-Necrosulfonamide is a racemic compound of Necrosulfonamide (HY-100573). Necrosulfonamide is a necroptosis inhibitor acting by selectively targeting the mixed lineage kinase domain-like protein (MLKL). Necrosulfonamide prevents MLKL-RIP1-RIP3 necrosome complex from interacting with its downstream effectors. MLKL is a critical substrate of RIP3 during the induction of necrosis.

    MLKL-IN-1
    Inhibitor
    MLKL-IN-1 is a covalent MLKL inhibitor with a KD of 50 μM.

    RIPK3-IN-3
    Inhibitor
    RIPK3-IN-3 (compound 20) is a selective inhibitor of RIP kinase RIPK3 (IC50=10 nM). RIPK3 mediates the phosphorylation of Mixed Lineage Kinase (MLKL) and causes necroptosis, while RIPK3-IN-3 inhibits p-MLKL oligomerization and thereby inhibits necroptosis. RIPK3-IN-3 also downregulates CXCL5 secretion and inhibits AsPC-1 cell migration and invasion.

    MLKL-IN-4
    Inhibitor
    MLKL-IN-4 (compound 56) is a potent MLKL (Mixed lineage kinase domain-like protein) inhibitor. MLKL-IN-4 inhibits necroptosis in HT-29 cells and acts downstream of MLKL phosphorylation, with EC50 of 82 nM. MLKL-IN-4 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
