Biological Activity

Description MS049 is a potent and selective inhibitor of PRMT4 and PRMT6 with IC50s of 34 nM and 43 nM, respectively.
PRMT4 [1]
(Cell-free assay)
PRMT6 [1]
(Cell-free assay)
34 nM 43 nM
In vitro

MS049 does not inhibit any of the methyltransferases at 50 μM or demethylases at 10 μM and does not display appreciable binding to any of the methyllysine/methylarginine reader proteins using the DSF assay at 200 μM. MS049 demonstrated excellent selectivity over a broad range of epigenetic and nonepigenetic targets. In cellular assays, MS049 potently inhibits the methyltransferase activity of PRMT4 and PRMT6 and reduces levels of Med12me2a and H3R2me2a in HEK293 cells[1].

Protocol (from reference)

Cell Research:


  • Cell lines: HEK293 cells
  • Concentrations: 0, 1, 10, and 50 μM
  • Incubation Time: 96 h
  • Method:

    HEK293 cells grown in DMEM supplemented with 10% FBS, penicillin (100 U/mL), and streptomycin (100 μg/mL) were seeded on 96-well plates at density 3000/well and treated with compounds at 0, 1, 10, and 50 μM concentrations for 96 h. The confluency was measured using IncuCyte ZOOM live cell imaging device and analyzed with IncuCyte ZOOM software based on phase contrast images.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
