Solubility (25°C)* In vitro DMSO 76 mg/mL (199.74 mM)
Ethanol 76 mg/mL (199.74 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
0.95mg/ml Taking the 1 mL working solution as an example, add 50 μL of 19 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.8mg/ml Taking the 1 mL working solution as an example, add 50 μL of 76 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description GSK591 (EPZ015866, GSK3203591) is a potent selective inhibitor of the arginine methyltransferase PRMT5 with IC50 of 4 nM.
Targets
PRMT5 [1]
(Cell-free assay)
4 nM
In vitro

In an in vitro biochemical assay, GSK591 potently inhibits the PRMT5/MEP50 complex from methylating (histone) H4 with IC50 = 11 nM. In Z-138 cells, GSK591 inhibits the symmetric arginine methylation of SmD3 with EC50 = 56 nM. Further, GSK591 is selective for PRMT5 (up to 50 micromolar) relative to a panel of methyltransferases[2][3].
