MS049 (hydrochloride)

MS049 is a potent and selective inhibitor of protein arginine methyltransferase 4 (PRMT4; IC₅₀ = 34 nM) and PRMT6 (IC₅₀ = 43 nM).¹ It is less active against additional type I PRMTs (IC₅₀s = >13, >22, and 1.6 µM for PRMT1, PRMT3, and PRMT8, respectively) and displays no inhibition against type II or type III PRMTs nor any additional methyltransferases or nonepigenetic targets tested.¹ MS049 has been shown to reduce the H3R2me2a mark in HEK293 cells with an IC₅₀ value of 0.97 µM and also, unexpectedly, to reduce H4R3me2a in HEK293 cells.¹ For more information on MS049 please visit the Structural Genomics Consortium (SGC). The negative control, MS049N, for MS049 is also available exclusively through the SGC. You can submit a request to receive the negative control here.
