EZM2302

EZM2302 is an inhibitor of protein arginine methyltransferase 4 (PRMT4, IC50 = 6 nM). It decreases asymmetric methylation of the PRMT4 substrate PABP1 (IC50 = 0.038 µM) and increases levels of demethylated SmB (EC50 = 0.018 µM) in RPMI-8226 multiple myeloma cells. EZM2302 inhibits proliferation in a panel of 36 hematopoietic cancer cell lines, with IC50 values of less than 100 µM for nine of the 15 multiple myeloma cell lines included in the panel. It reduces tumor growth and decreases asymmetric PABP1 methylation in tumor tissue in an RPMI-8226 mouse xenograft model when administered at doses of 75, 150, and 300 mg/kg twice per day. Intrathecal injection of EZM2302 (10 µg) reduces acute mechanical allodynia and thermal hyperalgesia in a mouse model of neuropathic pain induced by chronic constriction injury (CCI).Formal Name: 2-[2-[2-chloro-5-[(2R)-2-hydroxy-3-(methylamino)propoxy]phenyl]-6-(3,5-dimethyl-4-isoxazolyl)-5-methyl-4-pyrimidinyl]-2,7-diazaspiro[3.5]nonane-7-carboxylic acid, methyl ester.
