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.

    Necrosulfonamide
    Inhibitor 99.47%
    Necrosulfonamide is a MLKL and Gasdermin D (GSDMD) inhibitor, capable of separately inhibiting necroptosis and pyroptosis of cells. Necrosulfonamide does not affect the activation of upstream signals, but specifically inhibits the downstream executor oligomerization step. Necrosulfonamide reduces the expression of the key kinases NLRP3 and caspase-1 involved in necroptosis and pyroptosis, activate the Nrf2 pathway and the downstream antioxidant enzymes, and also downregulates a variety of inflammatory factors. Necrosulfonamide plays significant roles in various diseases such as neurodegenerative diseases (such as Parkinson’s disease), tissue damage and ischemia-reperfusion injury, inflammatory bowel disease, osteoarthritis and fracture repair, and hair loss by regulating two important programmed necrosis pathways.
