GSK126 (GSK2816126A) is a excellently specific EZH2 methyltransferase inhibitor ( IC50=9.9 nM).

XY1 is a close analogue of SGC707 (a potent, selective, and non-competitive inhibitor of PRMT3 with IC50 of 31 nM), intended as a negative control for SGC707 in studies involving PRMT3 action.

AMI-1 free acid is a potent, cell-permeable, and reversible inhibitor of protein arginine N-methyltransferases (PRMTs), with inhibitory concentration 50 (IC50) values of 8.8 μM for human PRMT1 and 3.0 μM for yeast-Hmt1p. It achieves its PRMTs inhibitory activity by obstructing peptide-substrate binding [1].

MS37452 is a competitive inhibitor of CBX7 chromodomain binding to H3K27me3 (Ki = 43 µM).

BIX-01294 trihydrochloride is an inhibitor of G9a histone methyltransferase.In a cell-free assay, the IC50=2.7 μM for G9a histone methyltransferase.

UNC 0631 is a effectvie histone methyltransferase G9a inhibitor (IC50=4 nM).

EZM 2302 (GSK3359088) is a selective, and orally available arginine methyltransferase CARM1 inhibitor (IC50: 6 nM).[1]

Tazemetostat hydrobromide (E-7438 hydrobromide) is a potent and selective EZH2 inhibitor. Tazemetostat hydrobromide inhibits the activity of human polycomb repressive complex 2 (PRC2)-containing wild-type EZH2 (Ki: 2.5 nM). Tazemetostat hydrobromide also inhibits EZH1 (IC50: 392 nM).
