AR antagonist 1 (compound 29) is a potent androgen receptor (AR) antagonist and binds to E3 ligase ligands with weak binding affinities to VHL protein in the synthesis of PROTAC ARD-266 (HY-133020).AR antagonist 1 (compound 29) is the ligand for target ligase of ARD-266. ARD-266 is a highly potent and VHL E3 ligase-based androgen receptor (AR) PROTAC degrader.
AR antagonist 1 exhibits micromolar binding affinity to its E3 ligase complex, it can be successfully employed for the design of highly potent and efficient PROTAC degraders.
PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein.PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
