Notes: ARV-771 is a proteolysis-targeting chimera (PROTAC) that drives the degradation of bromodomain and extra terminal domain (BET) family proteins.{33349} It is comprised of a BET-binding moiety conjugated via a linker to a von Hippel-Lindau (VHL) E3 ligase-binding moiety. ARV-771 induces degradation of bromodomain-containing protein 2 (BRD2), BRD3, and BRD4 in 22Rv1 castration-resistant prostate cancer (CRPC) cells with half-maximal degradation (DC50) values of less than 5 nM for all. It inhibits proliferation of and increases poly(ADP-ribose) polymerase (PARP) cleavage in 22Rv1 cells in a concentration-dependent manner. ARV-771 reduces full-length androgen receptor protein levels and prevents increases in ERG induced by the synthetic androgen R1881 in VCaP cells in a concentration-dependent manner. ARV-771 (30 mg/kg per day, s.c.) induces tumor regression in a 22Rv1 mouse xenograft model.
