A cell-permeable BET proteins degrader that inhibits castrate-resistent prostate cancer growth both in vitro and in vivo by downregulating AR and c-Myc levels.
ARV-771 is a bromodomain and extraterminal (BET) proteins degrader with a HIF-1?-derived von Hippel–Landau (VHL) E3 ligase-binding hydroxyproline and a BET-binding triazolo-diazepine acetamide. ARV-771 induces BET proteins degradation in castrate-resistent prostate cancer (CRPC) cultures (BRD2/3/4 DC50 <5 nM; 22Rv1, VCaP & LnCaP95) and reduces downstream c-Myc transcription with 10-500-fold higher potency than JQ-1, OTX015, and dBET1. ARV-771, but not JQ-1 or OTX015, effectively downregulates CRPC androgen receptor (30-300 nM) and causes CRPC tumor growth retardation/regression in mice in vivo (30 mg/kg s.c.; 22Rv1 and VCaP).
Bromodomain extraterminal protein (BETP) inhibitors transcriptionally repress oncoproteins and nuclear factor-κB (NF-κB) target genes that undermines the growth and survival of mantle cell lymphoma (MCL) cells. However, BET bromodomain inhibitor (BETi) treatment causes accumulation of BETPs, associated with reversible binding

BET bromodomain inhibitors have emerged as a promising therapy for numerous cancer types in preclinical studies, including neurofibromatosis type 1 (NF1)-associated malignant peripheral nerve sheath tumor (MPNST). However, potential mechanisms underlying resistance to these inhibitors in different cancers are not
The activated B cell (ABC-like) subtype of diffuse large B cell lymphoma (DLBCL) is characterized by chronic activation of signaling initiated by immunoglobulin μ (IgM). By analyzing the DNA copy number profiles of 1000 DLBCL tumors, we identified gains of

Proteolysis-targeting chimeras (PROTAC) are bifunctional molecules that hijack endogenous E3 ubiquitin ligases to induce ubiquitination and subsequent degradation of protein of interest. Recently, it has been shown that PROTACs with robust in vitro and in vivo activities and, in some

Proteolysis targeting chimeras are bifunctional small molecules capable of recruiting a target protein of interest to an E3 ubiquitin ligase that facilitates target ubiquitination followed by proteasome-mediated degradation. The first molecules acting on this novel therapeutic paradigm have just entered
