JJ-450

JJ-450 is a non-competitive antagonist androgen receptor (AR) that inhibits the transcriptional activity of wild-type AR and mutant ARF876L. JJ-450 has an IC50 of approximately 1-10 μM in inhibiting AR transcriptional activity in PC3 cells. It is selective for AR binding and does not compete with androgens for binding to the ligand binding domain (LBD) of AR. JJ-450 inhibits the transcriptional activity of AR and its splice variants (such as ARF876L) by inhibiting AR nuclear translocation and promoting the degradation of unliganded AR in the nucleus. JJ-450 can be used in castration-resistant prostate cancer (CRPC) studies that are resistant to Enzalutamide (MDV3100).
