A PROTAC-based androgen receptor (AR) degrader is a bifunctional small molecule, consisting of an AR ligand that binds to AR protein, and a ligand that binds to and recruits an E3 ligase complex, tethered together through a linker. Researchers report the discovery of exceptionally potent and orally bioavailable PROTAC AR degrader ARD-2585 (Compound 43). ARD-2585 is a promising AR degrader for extensive investigations for the treatment of advanced prostate cancer.
