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.

    ZBP1/RIP3/MLKL activator 1
    Activator 99.73%
    ZBP1/RIP3/MLKL activator 1 (compound 3a) is a synthetically derived quinoline compound. ZBP1/RIP3/MLKL Activator 1 induces DNA damage, enhances intracellular levels of reactive oxygen species (ROS), and triggers apoptosis via the caspase pathway. Furthermore, when apoptosis is inhibited, ZBP1/RIP3/MLKL Activator 1 promotes necroptotic cell death through the ZBP1-RIP3-MLKL pathway. ZBP1/RIP3/MLKL Activator 1 is utilized in oncological research, particularly in the selective targeting of cells with impaired apoptotic function.

    (E/Z)-Necrosulfonamide
    Inhibitor 98.84%
    (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.

    NecroIr2
    Activator 98.99%
    NecroIr2 is an iridium(III) complex, serves as necroptosis inducers in Cisplatin (HY-17394)-resistant lung cancer cells (A549R). NecroIr2 selectively accumulates in mitochondria, leading to oxidative stress and loss of mitochondrial membrane potential (MMP). NecroIr2 activates receptor-interacting serine-threonine kinase 3 (RIPK3) and mixed lineage kinase domain-like pseudokinase (MLKL), and regulates CDK4 expression.
