BETd-246 is an inhibitor of second-generation and PROTAC-based BET bromodomain (BRD), show antitumor activity.

PROTAC BRD4 ligand-1, a component of Protac GNE-987, is a ligand for BRD4 and acts as an inhibitor of BET.

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.

MS402 is a novel BD1-selective BET BrD inhibitor.

SNIPER(BRD)-1 is a chemical compound composed of a derivative of the IAP antagonist LCL-161 and the BET inhibitor (+)-JQ-1, linked together. It promotes the degradation of BRD4 through the ubiquitin-proteasome pathway and effectively degrades cIAP1, cIAP2, and XIAP with IC50 values of 6.8 nM, 17 nM, and 49nM, respectively[1].

BTR2004 is a selective PROTAC degrader targeting the BET family (BRD2/3/4) proteins. It facilitates the formation of a ternary complex with BRD proteins and KLHL20, leading to ubiquitination and proteasomal degradation via the UPS pathway. BTR2004 shows potential for research in PC3 prostate cancer and MDA-MB-231 breast cancer cell lines.

Mivebresib (ABBV-075), also known as ABBV-075, is a potent BET inhibitor (bromodomain (BRD)-containing protein) with potential antineoplastic activity. Upon administration, the bromodomain inhibitor ABBV-075 binds to the acetyl-lysine binding site in the BRD of certain BRD-containing protein(s), thereby preventing the interaction between those proteins and acetylated histones. This disrupts chromatin remodeling, prevents the expression of certain growth-promoting genes, and leads to an inhibition of cell growth in susceptible tumors. Also a potent inhibitor of MYC and the TMPRSS2-ETS fusion proteins.

BRD PHOTAC-I-3 is a photoswitchable BET bromodomain degrader (PHOTAC, PHOtochemically TArgeting Chimera). BRD PHOTAC-I-3 comprises a ligand for an E3 ligase, a photoswitch, and the BET bromodomain targeting ligand (+)-JQ1. Exhibits cytotoxicity and degrades BRD4, BRD3 and to a lesser extent BRD2 in lymphoblast cells upon irradiation with 390 nm light, but not in the dark.

I-BRD9 (GSK602) is the first selective cellular inhibitor for BRD9 with pIC50 of 7.3.
