BIX01294 is an inhibitor of G9a histone methyltransferase with IC50 of 2.7 μM in a cell-free assay, reduces H3K9me2 of bulk histones, also weakly inhibits GLP (primarily H3K9me3), no significant activity observed at other histone methyltransferases.
(H) Fold change of miR-200c expression in MCF7 cells under leptin and S3I-201/BIX01294 treatment (n=3, asterisk indicates P<0.05). Error bars denote ±SD.
UNC0638 is a potent, selective and cell-penetrant chemical probe for G9a and GLP with IC50 of <15 nM and 19 nM, respectively, shows selectivity over a wide range of epigenetic and non-epigenetic targets.
UNC0642 is a potent, selective inhibitor of histone methyltransferases G9a/GLP with IC50s less than 2.5 nM for G9a and GLP and shows more than 300-fold selective for G9a and GLP over a broad range of kinases, GPCRs, transporters, and ion channels.
Chaetocin, a natural product from Chaetomium species, is a histone methyltransferase inhibitor with IC50 of 0.8 μM, 2.5 μM and 3 μM for dSU(VAR)3-9, mouse G9a and Neurospora crassa DIM5, respectively.
