MLT-748

Research use only, not for human use.

MLT-748 (MLT748) is a potent, selective, allosteric inhibitor of MALT1 paracaspase with IC50 of 5 nM.

MLT-748 (MLT748) is a potent, selective, allosteric inhibitor of MALT1 paracaspase with IC50 of 5 nM, does not show inhibitory activity against 22 other tested human proteases (IC50>100 uM); binds MALT1 in the allosteric Trp580 pocket, reversibly binds and stabilizes human mutant MALT1-W580S with Kd of 13 nM, with affinity similar to that of the wild type MALT1 (Kd=42 nM); stabilizes MALT1-W580S in MALT1mut/mut B cells with EC50 of 69 nM, blocks cleavage of MALT1 substrates in human lymphocytes, including HOIL1, RelB, CYLD, and BCL10 (BCL10 cleavage IC50=31 nM), rescues MALT1 function in patient MALT1mut/mut lymphocytes.

Western Blot Analysis Cell Line:MALT1mut/mut patient immortalized B cells Concentration:2 μM Incubation Time:24 hours Result:Increased NF-κB signaling phosphorylation of both p65 and IκBα as early as 5 min after stimulation with PMA and ionomycin.
