MLK

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.

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-2 is an MLKL inhibitor with potential tumorigenic activity for the study of cellular necrosis-related diseases.

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.

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.

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

MLKL-IN-5 is a potent MLKL inhibitor that mediates necroptosis.

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].

PROTAC MLKL Degrader-1 (Compound 36) is a selective PROTAC degrader targeting MLKL, with a degradation maximum (D max) exceeding 90%. The compound incorporates modified cereblon (CRBN) ligands and a lenalidomide-linker within its structure, effectively inhibiting cell death in a TSZ-induced model of necroptosis.

(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.

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).

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.

PRT062607 hydrochloride (P505-15 Hydrochloride) is a selective inhibitor of Syk (IC50: 1 nM). It displays at least 80-fold selectivity for Syk over other kinases.

Cerdulatinib hydrochloride (PRT2070 hydrochloride) is an oral active, multi-targeted tyrosine kinase inhibitor with IC50 of 12 nM 6 nM 8 nM 0.5 nM and 32 nM for JAK1 JAK2 JAK3 TYK2 and Syk, respectively. Also inhibits 19 other tested kinases with IC50 less than 200 nM.

LY-364947 (HTS466284) is a potent ATP-competitive inhibitor of TGFβR-I.

(E Z)-Necrosulfonamide is a novel inhibitor of MLKL.

AZ7550, an active metabolite of AZD9291, inhibits the activity of IGF1R (IC50: 1.6 μM).

IM-54 is a cell-permeable, effective, and selective necrosis inhibitor.
