MALT1-MI-2 (MI-2) --- MALT1 inhibitor

MALT1-MI-2 (MI-2) is a highly potent and selective small molecule directly binding to MALT1 and irreversibly suppressing its protease function. MI-2 concentrated within human ABC-DLBCL cells and irreversibly inhibited cleavage of MALT1 substrates with EC50 < 1 µM (HBL-1 ~200 nM; TMD8 ~500 nM). This was accompanied by NF-κB pathway suppression, c-REL nuclear localization inhibition, and NF-κB target gene downregulation. MI-2 was nontoxic to mice, and displayed selective activity against ABC-DLBCL cell lines in vitro and xenotransplanted ABC-DLBCL tumors in vivo. It was also effective against primary human non-germinal center B cell-like DLBCLs ex vivo.
