Biochem/physiol Actions

EPZ015666 (GSK3235025) is a protein arginine methyltransferase PRMT5 inhibitor with an IC50 value of of 22 nM in biochemical assays and no inhibition up to the maximum tested concentration of 50 μM against a panel of 20 other protein methyltransferases. Inhibition was uncompetitive with respect to SAM. EPZ015666 showed dose-dependent antitumor activity in multiple in vitro and in vivo mantle cell lymphoma (MCL) models with treatment of MCL cell lines leading to inhibition of SmD3 methylation and cell death.
