mixed lineage kinase

(E)-Necrosulfonamide ((E)-Necrosulfonamide) is an inhibitor of necroptosis. Blocks mixed lineage kinase domain-like protein (MLKL), a critical substrate of receptor-interacting serine-threonine kinase 3 (RIP3) during necrosis. Prevents MLKL-RIP1-RIP3 necrosome complex from interacting with downstream necrosis effectors. Binds and inhibits gasdermin D. Inhibits pyroptosis.

GW806742X is an inhibitor of Mixed Lineage Kinase Domain-Like protein (MLKL) which binds the MLKL pseudokinase domain (Kd: 9.3 μM) with anti-necroptosis activity. GW806742X has activity against VEGFR2.

URMC-099 is an orally bioavailable, brain penetrant MLK inhibitor (IC50: 19 42 14 150 nM, for MLK1 MLK2 MLK3 DLK), and also inhibits LRRK2 activity (IC50: 11 nM).

PROTAC MLKL Degrader-2, a PROTAC that targets MLKL (Mixed Lineage Kinase), incorporates the PROTAC target protein ligand, E3 ligase ligand Thalidomide, and PROTAC Linker N-Methylpiperazine. The conjugate of the E3 ubiquitin ligase ligand and Linker is Thalidomide-N-Methylpiperazine. This compound exhibits antinecroptotic activity in human cell lines and effectively degrades MLKL in the HT-29 xenograft mouse model.

NecroIr1, an iridium(III) complex, acts as a necroptosis inducer in Cisplatin-resistant lung cancer cells (A549R). It selectively targets mitochondria, causing oxidative stress and reducing mitochondrial membrane potential (MMP). By activating receptor-interacting serine-threonine kinase 3 (RIPK3) and Mixed Lineage Kinase (MLKL), and modulating CDK4 expression, NecroIr1 facilitates cell death mechanisms [1].

MLK-IN-1 (US20140256733A1, compound 68) is a highly potent and selective inhibitor of mixed lineage kinase 3 (MLK-3). It exhibits excellent brain penetration and specifically targets MLK-3.

TC13172 is an inhibitor of mixed lineage kinase domain-like protein (EC50: 2 nM for HT-29 cells).

MLK-IN-2 (Compound 9a), with its 3H-imidazole [4,5-b] pyridine structure, serves as a potent Mixed Lineage Kinase 3 (MLK3) inhibitor with an IC50 value of 6 nM. This compound is valuable for research in cancer and neurodegenerative diseases [1].

MLKL-IN-6 (compound P28) is a mixed lineage kinase inhibitor that specifically targets the Mixed Lineage Kinase domain-like (MLKL) protein. It effectively prevents MLKL phosphorylation and oligomerization, which are critical steps in cell necrosis. Additionally, MLKL-IN-6 restrains immune cell death, diminishes adhesion factor expression, exhibits low cytotoxicity, impedes hepatic stellate cell activation, decreases liver fibrosis marker levels, and exerts anti-fibrotic effects [1].

MLK3-IN-1 (Compound 37) is a selective inhibitor of mixed-lineage kinase 3 (MLK3) with an IC50 of less than 1 nM. It also inhibits FAK with an IC50 of 15.5 μM. In both murine and human liver microsomes, MLK3-IN-1 demonstrates excellent metabolic stability.

NecroIr2, an iridium(III) complex, functions as a necroptosis inducer in cisplatin-resistant lung cancer cells (A549R). It preferentially accumulates in mitochondria, causing oxidative stress and a reduction in mitochondrial membrane potential (MMP). Moreover, NecroIr2 initiates the activation of receptor-interacting serine threonine kinase 3 (RIPK3) and mixed lineage kinase domain-like pseudokinase (MLKL), while also regulating CDK4 expression [1].
