GSK591

GSK591 is a chemical probe for protein arginine methyltransferase 5 (PRMT5) that potently inhibits the PRMT5/MEP50 complex from methylating histone H4 (IC50 = 11 nM) in vitro. GSK591 is selective for PRMT5 (up to 50 µM) relative to a panel of other methyltransferases. In Z-138 cells, GSK591 inhibits the symmetric arginine methylation of SmD3 with an EC50 value of 56 nM.
