ZEN-3411 is an orally available and potent BET inhibitor that inhibits BRD4(BD1), BRD4(BD2), and BRD4(BD1BD2) and suppresses the growth of tumor cells overproducing BET proteins.

(S)-GNE-987 binds to the BRD4 BD1(IC50=4 nM) and BD2 (3.9 nM) bromodomains and can be used to design PROTAC-Antibody Conjugate (PAC).

ZEN-3862 (Willardiine) is an inhibitor of BET(IC50s of 0.16 and 0.13 μM for BRD4(BD1) and BRD4(BD2) , respectively). ZEN-3862 can be used to form PROTACs to induce degradation of BRD4.

BY27, a potent and selective BET BD2 inhibitor (Ki: 3.1 nM) with anticancer activity, inhibits BD1/BD2 of BRD2, BRD3, BRD4, and BRDT, and suppresses tumor growth.

CF53 is a highly potent, selective, and orally active inhibitor of BET protein, with a Ki of <1 nM, Kd of 2.2 nM, and an IC50 of 2 nM for BRD4 BD1. CF53 binds to both the BD1 and BD2 domains of BRD2, BRD3, BRD4, and BRDT BET proteins with high affinities, being very selective over non-BET bromodomain-containing proteins. CF53 exhibits potent anti-tumor activity both in vitro and in vivo.

MS417 (GTPL7512) is an inhibitor of BET-specific BRD4(BRD4-BD1 and BRD4-BD2 with IC50s of 30, 46 nM and Kds of 36.1, 25.4 nM, respectively), with weak selectivity at CBP BRD with IC50 of 32.7 μM.

BRD4 Inhibitor-20 is a potent bromodomain protein 4 (BRD4) inhibitor with oral activity, demonstrating antiproliferative effects in cancer cell lines and used in studies of various cancers, including colon cancer.

MS402 is a novel BD1-selective BET BrD inhibitor.

BRD4 Inhibitor-10 is an inhibitor of BRD4-BD1 (IC50: 8 nM).

HJB97 is used for the design of potential PROTAC BET degrader. It also has antitumor activity. HJB97 is a high-affinity inhibitor of BET (Kis: 0.9 nM (BRD2 BD1), 0.27 nM (BRD2 BD2), 0.18 nM (BRD3 BD1), 0.21 nM (BRD3 BD2), 0.5 nM (BRD4 BD1), 1.0 nM (BRD4 BD2), respectively).

NI-42 is a structurally orthogonal chemical probe for the BRPFs and is biased. It effective inhibitor of the BRD of the BRPFs (IC50s of BRPF1/2/3=7.9/48/260 nM; Kds of BRPF1/2/3=40/210/940 nM). It also has excellent selectivity over nonclass IV BRD protei

GSK778 is a potent and selective inhibitor of BD1 bromodomain such as BRD2 BD1 (IC50s = 75 nM), BRD3 BD1 (IC50s = 41 nM), BRD4 BD1 (IC50s = 41 nM), and BRDT BD1 (IC50s = 143 nM). GSK778 inhibits proliferation, induces a cell cycle arrest and apoptosis.

ZEN-3219 is a BET inhibitor, which has inhibitory effect on BRD4(BD1), BRD4(BD2) and BRD4(BD1BD2). ZEN-3219 has inhibitory effect on BRD4(BD1), The IC50 values of BRD4(BD2) and BRD4(BD1BD2) were 0.48, 0.16 and 0.47 μM, respectively. ZEN-3219 is a component of PROTAC molecule and can induce BRD4 degradation.

PROTAC BRD4 Degrader-1 is an efficacious degrader of BRD4(BRD4 BD1,IC50 of 41.8 nM).

dBET57 is heterobifunctional degrader of BRD4 based on the PROTAC technology, exhibits significant degradation of BRD4BD1 with a DC50 5h of 500 nM ,and inactive on BRD4BD2

SRX3212 is a Novel BRD4 PI3Kα inhibitor, displaying an IC50 of 3.7 nM toward BRD4BD1 and 32 nM toward BRD4BD2, and therefore was~65-fold more potent inhibitor of BRD4BD1 and~48-fold more potent inhibitor of BRD4BD2 than SF2523 (GLXC-10641), retaining its high inhibitory activity for PI3Kα (IC50: 22 nM).

PROTAC BRD4 Degrader-14, a PROTAC (Proteolysis Targeting Chimera) linked by ligands to von Hippel-Lindau and BRD4, exhibits IC50 values of 1.8 nM and 1.7 nM for BRD4 BD1 and BD2, respectively. This compound effectively degrades the BRD4 protein in PC3 prostate cancer cells [1].

GSK737 is a dual inhibitor of BRD4 BD1 and BD2, exhibiting pIC50 values of 5.3 and 7.3, respectively. It demonstrates low clearance, along with favorable solubility and permeability in rats [1].
