Description

ARCC 4 is a PROTAC, acting as an androgen receptor degrader. ARCC-4 is a low-nanomolar androgen receptor degrader able to degrade about 95% of cellular androgen receptors. ARCC-4 inhibits prostate tumor cell proliferation, degrades clinically relevant androgen receptor point mutants and unlike enzalutamide, retains antiproliferative effect in a high androgen environment. Thus, ARCC-4 exemplifies how protein degradation can address the drug resistance hurdles of enzalutamide.

How to use

In Vitro:

ARCC-4 induces apoptosis and inhibiting proliferation of AR-amplified prostate cancer cells. ARCC-4 enhances protein-protein interactions between AR and VHL, thereby promoting the association of the trimeric complex. ARCC-4 (0.1-10, 000 nM; 20 hours) potently degrades AR with a D50 of 5 nM and Dmax of over 95%. ARCC-4 (100 nM; 12 hours) shows near complete AR degradation (>98%) in prostate cancer cells. ARCC-4 selectively degrades AR via the proteasome but not PR-A or PR-B suppression. ARCC-4 shows efficacy against clinically relevant AR mutations. ARCC-4 maintains activity despite elevated androgen levels.
