BETbromodomain inhibitor 1 is an orally active, selective inhibitor of bromodomain and extra-terminal (BET) proteins. It specifically inhibits BRD4 with an IC50 of 2.6 nM. Additionally, BETbromodomain inhibitor 1 demonstrates high affinities towards BRD2(2), BRD3(2), BRD4(1), BRD4(2), and BRDT(2) with Kd values of 1.3 nM, 1.0 nM, 3.0 nM, 1.6 nM, and 2.1 nM, respectively. This compound exhibits anti-cancer activity.
FKBP12 PROTAC dTAG-7 (dTAG-7) is a heterobifunctional compound that selectively degrades the BETbromodomain transcriptional co-activator BRD4 by connecting BETbromodomains to the E3 ubiquitin ligase CRBN. Additionally, it serves as a degrader of FKBP12F36V when FKBP12F36V is expressed in-frame with a targeted protein.
