Z-VRPR-FMK is a selective cell permeable and irreversible MALT1 inhibitor. It inhibits NF-kappaB-dependent gene expression and affects the growth, proliferation and survival of activated B cell-like diffuse large B cell lymphomas (ABC-DLBCL) and germinal center B cell like diffuse large B cell lymphoma (GCB-DLBCL) cell lines. Z-VRPR-FMK is shown to inhibit the autoprocessing activity of MCA2ac (calcium dependent) in Trypanosoma brucei.
