ar antagonist-1

AR antagonist 1 is a potent antagonist of the androgen receptor. It binds to E3 ligase ligands with weak binding affinities to VHL protein in the synthesis of PROTAC ARD-266.

Androgen receptor antagonist 1, an orally available full androgen receptor antagonist (IC50: 59 nM), is utilized in the synthesis of PROTAC AR degraders, achieving 24% and 47% AR protein degradation in LNCaP cells at concentrations of 1 μM and 10 μM, respectively.

PROTAC AR-NTD antagonist 1 (compound 18) is a small molecule from the protein-targeting chimeras (PROTACs) that selectively targets the N-terminal domain (AR-NTD) of the Androgen Receptor variant AR-V7. By antagonizing AR-NTD, it effectively degrades AR-V7 protein and induces apoptosis in prostate cancer (PC) cells, with degradation efficiencies of 62.2% (1 μM) and 71.1% (5 μM) in VCaP cells [1].
