ARV 771

Potent BET bromodomain PROTAC® degrader (DC50 = < 1nM). Comprises a BRD4-binding moiety joined by a linker to a ligand for Von Hippel-Lindau (VHL) protein. Degrades BRD2/3/4 in castration-resistant prostate cancer (CRPC) cell lines. Reduces androgen receptor levels and induces apoptosis in CRPC cells in vitro. Down-regulates BRD4 and induces tumor regression in CRPC xenografts in mice. Also reduces leukemia burden in a mouse model. Induces degradation of BRD-tagged CAR (chimeric antigen receptor) in T cells.

How to use

In Vitro:

ARV-771 is a potent small-molecule pan-BET degrader based on proteolysis-targeting chimera (PROTAC) technology, demonstrates dramatically improved efficacy in cellular models of CRPC as compared with BET inhibition. ARV-771 treatment of CRPC cells results in apoptosis.

In Vivo:

ARV-771 induces degradation in vivo. ARV-771 results in suppression of both AR signaling and AR levels and leads to tumor regression in a CRPC mouse xenograft model.
