ARD-266 is a highly potent and VHL E3 ligase-based androgen receptor (AR) PROTAC degrader. ARD-266 effectively induces degradation of AR protein in AR-positive LNCaP, VCaP, and 22Rv1 prostate cancer cell lines with DC50 values of 0.2-1 nM[1].
ARD-266 (Compound 11; 100 nM; 1-24 hours; LNCaP and VCaP cells) treatment effectively reduces the AR protein level within 3 h and achieves near-complete AR elimination with a 6 h treatment in the LNCaP cells[1].ARD-266 (Compound 11; 1-10000 nM; 24 hours; LNCaP cells) treatment effectively suppresses the expression of PSA, TMPRSS2, and FKBP5 genes in a dosedependent manner and is capable of reducing the mRNA levels of PSA, TMPRSS2, and FKBP5 genes by >50% at 10 nM in the LNCaP cell line[1].

Discovery of Highly Potent and Efficient PROTAC Degraders of Androgen Receptor (AR) by Employing Weak Binding Affinity VHL E3 Ligase Ligands
J Med Chem 2019 Dec 26;62(24):11218-11231.PMID:31804827DOI:10.1021/acs.jmedchem.9b01393
Androgen receptor (AR) is a validated therapeutic target for the treatment of metastatic castration-resistant prostate cancer (mCRPC). We report herein our design, synthesis, and biological characterization of highly potent small-molecule proteolysis targeting chimera (PROTAC) AR degraders using a potent AR antagonist and E3 ligase ligands with weak binding affinities to VHL protein. Our study resulted in the discovery of 11 (ARD-266), which effectively induces degradation of AR protein in AR-positive (AR+) LNCaP, VCaP, and 22Rv1 prostate cancer cell lines with DC50 values of 0.2-1 nM. ARD-266 is capable of reducing the AR protein level by >95% in these AR+ prostate cancer cell lines and effectively reduces AR-regulated gene expression suppression. For the first time, we demonstrated that an E3 ligand with micromolar binding affinity to its E3 ligase complex can be successfully employed for the design of highly potent and efficient PROTAC degraders and this finding may have a significant implication for the field of PROTAC research.
