Description: Potent inhibitor of androgen receptor (AR)
Chemical Name: (1β,11β,12α)-11,20-Epoxy-1,11,12-trihydroxypicrasa-3,13(21)-diene-2,16-dione
Purity: ≥98% (HPLC)

Biological Activity

Potent androgen receptor (AR) inhibitor (IC50 = 69 nM). Disrupts the AR-chaperone complex by binding p23 and blocking AR interaction with HSP90 causing UPS degradation of AR. Inhibits Huh7 cancer cell growth via G0/G1 cell cycle arrest and apoptosis in vitro and in vivo. Inhibits growth and metastasis of certain prostate cancer cell lines. Orally bioavailable.
