protac ar degrader-8

PROTAC AR Degrader-8 (Compound NP18) functions as a PROTAC degrader targeting the androgen receptor (AR) and effectively degrades AR-FL in both 22Rv1 and LNCaP cells with DC50 values of 0.018 μM and 0.14 μM, respectively. It also degrades AR-V7 in 22Rv1 cells with a DC50 of 0.026 μM. Additionally, PROTAC AR Degrader-8 inhibits the proliferation of 22Rv1 and LNCaP cancer cells, exhibiting IC50 values of 0.038 μM and 1.11 μM. It induces cell cycle arrest at the G2 M phase and triggers apoptosis in 22Rv1 cells (apoptosis). Demonstrating anticancer efficacy, PROTAC AR Degrader-8 shows activity in both mouse and zebrafish models.

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].

AR ligand-33 is a ligand for the androgen receptor (AR), and it can be used as a target protein ligand for the synthesis of PROTAC AR Degrader-8.
