Mivebresib(ABBV-075) is a novel BET family bromodomain inhibitor. It binds bromodomains of BRD2/4/T with similar affinities (Ki of 1-2.2 nM) and highly selective for 18 bromodomain proteins tested (Kd > 1 μM more than 600-fold selectivity vs. BRD4), but exhibits roughly 10-fold weaker potency towards BRD3 (Ki of 12.2 nM) and has moderate activity towards CREBBP (Kd = 87 μM 54-fold selectivity vs. BRD4).
Citarinostat (ACY-241) is an orally available selective HDAC6 inhibitor with IC50 of 2.6 nM and 46 nM for HDAC6 and HDAC3, respectively. It has 13 to 18-fold selectivity towards HDAC6 in comparison to HDAC1-3.
LLY-283 is the potent and selective SAM-competitive chemical probe for PRMT5. It inhibits PRMT5 enzyme activity with IC50 of 20 nM for methylation of an H4R3 derived peptide substrate, and shows greater than 100-fold selectivity over other histone methyltransferases and non-epigenetic targets.
PF-06726304 is a selective EZH2 inhibitor with Ki values of 0.7 nM and 3 nM for WT EZH2 and Y641N respectively also inhibits H3K27me3 with the IC50 value of 15 nM.
WT161 is a potent, selective, and bioavailable HDAC6 inhibitor with IC50 values of 0.4 nM, 8.35 nM and 15.4 nM for HDAC6, HDAC1 and HDAC2, respectively shown to have >100-fold selectivity over other HDACs.
EED226 is a potent, selective, and orally bioavailable a novel allosteric Polycomb repressive complex 2 (PRC2) inhibitor with an IC50 of 23.4 nM when the H3K27me0 peptide was used as substrate and an IC50 of 53.5 nM when the mononucleosome was used as the substrate. It directly binds to the H3K27me3 binding pocket of EED.
Chidamide is a low nanomolar inhibitor of HDAC1, 2, 3, and 10, the HDAC isotypes well documented to be associated with the malignant phenotype with IC50 values of 95, 160, 67, 78 nM for HDAC1, 2, 3, 10 respectively.
CP2 is a cyclic peptide that inhibits the JmjC histone demethylases KDM4 with IC50 values of 42 nM and 29 nM for KDM4A and KDM4C, respectively.
