androgen receptor antagonist 1

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

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.

CDK9 Antagonist-1 (compounds 11c) is a potent and selective CDK9 degrader based on PROTAC, with an IC50 of 17 μM in MCF-7 cell lines. Natural product Wogonin binds ubiquitin E3 ligase cereblon (CRBN) via a linker to form PROTAC[1]. CDK9|17 μM (IC50, MCF-7 cells) [1]. Bian J , et al.

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].
