ARD-61 is a highly potent, effective and specific PROTAC androgen receptor (AR) degrader. ARD-61 potently and effectively induces AR and progesterone receptors (PR) degradation in AR+ cancer cell lines. ARD-61 induces apoptosis and effectively induces tumor growth inhibition in the MDA-MB-453 xenograft model in mice.

体外研究(In Vitro)
ARD-61 binds to AR protein through its AR antagonist portion and von Hippel-Lindau (VHL)/cullin 2 E3 ligase through its VHL ligand portion to recruit AR protein to cullin 2 for ubiquitination, followed by proteasome-dependent AR degradation. ARD-61 (0.001-100 μM; for 7?days) has IC50 values of 235?nM and 121?nM in the MDA-MB-453 and HCC1428 cell lines, which have the highest AR expression, respectively. ARD-61 demonstrates partial cell growth inhibition, delivering IC50 values of 39, 147, and 380?nM, respectively, in the MCF-7, BT-549 and MDA-MB-415 cell lines, which have a moderate level of AR protein. ARD-61 (25-100000 nM; 6-72 h) induces G2/M cell cycle arrest in a dose- and time-dependent manner in each of these three AR+ breast cancer cell lines. ARD-61 (25-100000 nM; 72 h) induces apoptosis in the MDA-MB-453 and HCC1428 cell lines.
体内研究(In Vivo)
ARD-61 (25, 50?mg/kg/day; ip; for 75 days) effectively inhibits tumor growthin the MDA-MB-453 xenograft tumor model in male SCID mice.
ARD-61 (25?mg/kg; ip; single dose) effectively and rapidly reduces the AR protein in the MDA-MB-453 xenograft tissue, with the effect persisting for at least 24?h. ARD-61 is very effective in reducing the mRNA level of WNT7B in a time-dependent manner. has not independently confirmed the accuracy of these methods. They are for reference only.
