AR antagonist 4
AR antagonist 4 is an orally active androgen receptor (AR) antagonist with a DC50 of 2.84 μM in LNCaP human prostate cancer cells. AR antagonist 4 inhibits dihydrotestosterone-induced AR transcriptional activity, promotes proteasome-dependent AR degradation, and dose-dependently promotes AR-V7 degradation. AR antagonist 4 can be used for the research of metastatic castration-resistant prostate cancer.
