EN219 is a synthetic recruiter of the E3 ubiquitin ligase RNF114.1It binds to cysteine 8 (C8) in the intrinsically disordered region of RNF114 (RNF114-C8; IC50= 470 nM) and inhibits RNF114-induced autoubiquitination and p21 ubiquitination in a cell-free assay when used at a concentration of 50 μM. EN219 (1 μM) also interacts with cysteine residues in the tubulin β1 chain (TUBB1), heat shock protein 60 (Hsp60), also known as Hsp family D member 1 (HspD1), and histone H3.1 (HIST1H3A) in 231MFP human breast cancer cells in a proteomic profiling assay. It has been linked to the bromodomain and extra terminal domain (BET) inhibitor ligand (+)-JQ1 for use as a proteolysis-targeting chimera (PROTAC) to degrade bromodomain-containing protein 4 (BRD4) in 231MFP cells. 1.Luo, M., Spradlin, J.N., Boike, L., et al.Chemoproteomics-enabled discovery of covalent RNF114-based degraders that mimic natural product functionCell Chem.

GNE-207 is a selective and orally bioavailable inhibitor of the bromodomain of CBP (IC50: 1 nM). It has a selective index of >2500-fold against BRD4 (1). GNE-207 displays excellent CBP potency (EC50: 18 nM for MYC expression in MV-4-11 cells).

PROTAC BRD4 Degrader-17 (compound 13i), a potent inhibitor, exhibits IC50 values of 29.54 nM (BRD4 (BD1)) and 3.82 nM (BRD4 (BD2)), effectively reducing Cyclin B1 expression linked with G2 M phase progression and significantly inducing apoptosis in MV-4-11 cells [1].

CAY17c is an inhibitor of bromodomain-containing protein 4 (BRD4; IC50= 0.71 μM), as well as class I histone deacetylases (HDACs; IC50s = 0.046, 0.058, 0.075, and 0.167 μM for HDAC1, -2, -3, and -8, respectively) and class IIb HDACs (IC50s = 0.073 and 0.923 μM for HDAC6 and HDAC10, respectively).1It is selective for these enzymes over BRD2, -3, and -T (IC50s = >20 μM for all), as well as over HDAC4, -5, -7, -9, and -11 (IC50s = >10 μM for all). CAY17c inhibits the proliferation of HCT116, SW620, and DLD-1 colorectal cancer cells (IC50s = 0.45, 1.78, and 2.11 μM, respectively), as well as induces apoptosis and autophagy in HCT116 cells. It reduces tumor growth in an HCT116 mouse xenograft model when administered at doses of 15 and 30 mg/kg. 1.Pan, Z., Li, X., Wang, Y., et al.Discovery of thieno[2,3-d]pyrimidine-based hydroxamic acid derivatives as bromodomain-containing protein 4/histone deacetylase dual inhibitors induce autophagic cell death in colorectal carcinoma cellsJ.
