dBET57 is a hybrid compound that drives the selective proteasomal degradation of bromodomain-containing protein 4 (BRD4).1 It is characterized as a proteolysis-targeting chimera (PROTAC) and contains JQ1, which binds bromo- and extra-terminal domain (BET) proteins, linked to thalidomide, a ligand for the E3 ubiquitin ligase cereblon. dBET57 is selective for inhibiting the interaction between cereblon and bromodomain 1 of BRD4 (BRD4BD1) over the interaction between cereblon and BRD4BD2 with apparent cooperativity factor α (αapp) values of 0.8 and less than 0.1, respectively, in an assay using purified bromodomains. It reduces BRD4BD1 protein levels in vitro with a half-maximal degradation (DC50) value of approximately 500 nM after five hours but does not reduce levels of BRD4BD2.

The BRD4 Inhibitor dBET57 Exerts Anticancer Effects by Targeting Superenhancer-Related Genes in Neuroblastoma
J Immunol Res 2022 Nov 16;2022:7945884.PMID:36438198DOI:PMC9691391
Neuroblastoma (NB) is the most common solid tumor of the neural crest cell origin in children and has a poor prognosis in high-risk patients. The oncogene MYCN was found to be amplified at extremely high levels in approximately 20% of neuroblastoma cases. In recent years, research on the targeted hydrolysis of BRD4 to indirectly inhibit the transcription of the MYCN created by proteolysis targeting chimaera (PROTAC) technology has become very popular. dBET57 (S0137, Selleck, TX, USA) is a novel and potent heterobifunctional small molecule degrader based on PROTAC technology. The purpose of this study was to investigate the therapeutic effect of dBET57 in NB and its potential mechanism. In this study, we found that dBET57 can target BRD4 ubiquitination and disrupt the proliferation ability of NB cells. At the same time, dBET57 can also induce apoptosis, cell cycle arrest, and decrease migration. Furthermore, dBET57 also has a strong antiproliferation function in xenograft tumor models in vivo. In terms of mechanism, dBET57 targets the BET protein family and the MYCN protein family by associating with CRBN and destroys the SE landscape of NB cells. Combined with RNA-seq and ChIP-seq public database analysis, we identified the superenhancer-related genes TBX3 and ZMYND8 in NB as potential downstream targets of dBET57 and experimentally verified that they play an important role in the occurrence and development of NB. In conclusion, these results suggest that dBET57 may be an effective new therapeutic drug for the treatment of NB.
