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.

ARD-1676 is an orally administered androgen receptor (AR) PROTAC degrader that combines an AR ligand with a cereblon ligand. It demonstrates AR-degrading activity both in vitro and in vivo, and effectively inhibits VCaP tumor growth in mouse xenograft models [1].

VHL Ligand 8, a VHL ligand essential for synthesizing ARD-266, acts as a highly potent VHL E3 ligase-based androgen receptor (AR) PROTAC degrader. It efficiently facilitates the degradation of AR protein in AR-positive prostate cancer cell lines LNCaP, VCaP, and 22Rv1, exhibiting DC50 values ranging from 0.2-1 nM [1].

ARD-2051 is a potent, orally active proteolysis-targeting chimera degrader of the androgen receptor (AR), exhibiting DC50 values of 0.6 nM in degrading AR protein within LNCaP and VCaP prostate cancer cell lines. It holds potential for prostate cancer research applications [1].

A031, a potent PROTAC androgen receptor (AR) degrader, demonstrates significant efficacy with an IC50 value under 0.25 μM for AR protein degradation. Additionally, it exhibits an inhibitory impact on tumor growth in zebrafish models of human prostate cancer (VCaP) [1].

ARD-69 is a Highly Potent Proteolysis Targeting Chimera (PROTAC) Degrader of Androgen Receptor (AR) for the Treatment of Prostate Cancer. ARD-69 induces degradation of AR protein in AR-positive prostate cancer cell lines in a dose- and time-dependent mann

PROTAC AR-NTD antagonist 1 (compound 18) is a small molecule belonging to 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, this compound effectively degrades AR-V7 protein and triggers apoptosis in prostate cancer (PC) cells, with degradation efficiencies in VCaP cells recorded at 62.2% (1 μM) and 71.1% (5 μM), as noted in reference [1].

ARD-2128 is a highly potent, orally bioavailable PROTAC (proteolysis-targeting chimera) degrader of the androgen receptor (AR), effectively diminishing AR protein levels, suppressing AR-regulated gene expression in tumor tissues, and inhibiting tumor growth without evident toxicity. This compound holds promise for prostate cancer research.

Boc-Pip-alkyne-Ph-COOH, a PROTAC linker characterized by its alkyl/ether composition, plays a crucial role in synthesizing PROTACs including ARD-266. This compound demonstrates significant efficacy in promoting the degradation of androgen receptor (AR) protein across AR-positive prostate cancer cell lines such as LNCaP, VCaP, and 22Rv1, showcasing DC50 values ranging from 0.2-1 nM[1].

ARD-266 is a highly potent and VHL E3 ligase-based androgen receptor (AR) PROTAC degrader. ARD-266 effectively induces the degradation of AR protein in AR-positive LNCaP, VCaP, and 22Rv1 prostate cancer cell lines (DC50s: 0.2-1 nM).
