MI 2

MI 2 is an inhibitor of the paracaspase MALT1 with an IC50 value of 5.84 µM in a fluorescence assay. It inhibits the growth of MALT1-dependent activated B cell-like diffuse large B cell lymphoma (ABC-DLBCL) cell lines (GI50s = 0.2, 0.5, 0.4, and 0.4 µM for HBL-1, TMD8, OCI-Ly3, and OCI-Ly10 cells, respectively). MI 2 inhibits cleavage of the MALT1 target protein CYLD in a dose-dependent manner in HBL-1 cells but does not inhibit caspase-3, caspase-8, and caspase-9, which are structurally similar to MALT1. MI 2 (25 mg/kg, i.v.) reduces tumor size in TMD8 and HBL-1 mouse xenograft models.Formal Name: 2-chloro-N-[4-[5-(3,4-dichlorophenyl)-3-(2-methoxyethoxy)-1H-1,2,4-triazol-1-yl]phenyl]-acetamide.
