Mepazine hydrochloride (Pecazine hydrochloride) is a potent and selective MALT1 protease inhibitor with IC50s of 0.83 and 0.42 μM for GSTMALT1 full length and GSTMALT1 325-760, respectively. Mepazine hydrochloride affects viability of ABC-DLBCL cells by enhancing apoptosis.

How to use

In Vitro:

Mepazine (5-20 μM; 4 days) causes a decrease of cell viability in the activated B cell subtype of diffuse large B cell lymphoma (ABCDLBCL) cells, without significantly affecting GCB-DLBCL cells.

In Vivo:

Mepazine (16 mg/kg; intraperitoneal administration) interferes with growth and induces apoptosis of ABC-DLBCL cell line OCI-Ly10 in NOD/scid IL-2Rgnull (NSG) mice with a murine DLBCL xenogeneic tumor model. Daily administration of Mepazine strongly impairs the expansion of the ABC-DLBCL cell line OCI-Ly10.
