BWA-522 is an orally available small molecule protein-targeting chimera (PROTACs) with significant degradation effect on AR-FL and AR-V7. BWA-522 antagonizes the N-terminal domain (AR-NTD) of the androgen receptor (Androgen Receptor) and induces apoptosis in PC cells. BWA-522 inhibits tumor growth in LNCaP xenograft model studies (60 mg/kg, po; TGI=76%). The efficiencies of BWA-522 in degrading AR-V7 and AR-FL were 77.3% (1 μM) and 72.0% (5 μM) in VCaP and LNCaP cells, respectively.
