EPI-001, a selective inhibitor of Androgen Receptor (AR), targets transactivation unit 5 (Tau-5) of the AR. EPI-001 can inhibit transactivation of the AR amino-terminal domain (NTD), with an IC50 of ~6 μM. EPI-001 is also a selective modulator of PPARγ. EPI-001 is active against castration-resistant prostate cancer.

How to use

In Vitro:

EPI-001 (5-100 μM; 7 d) inhibits PCa/CRPC cell growth in a dose-dependent manner. EPI-001 (50 μM) inhibits endogenous AR mRNA and protein expression in PCa and CRPC cell lines. EPI-001 (50 μM) inhibits transcriptional activity of both AR TAU1 and TAU5.

In Vivo:

EPI-00 (20 mg/kg; i.v. every 5 d for 25 d) inhibits the growth of tumors and has no general toxicity in vivo. EPI-00 (50 mg/kg; i.v.) blocks the androgen-axis and inhibits androgen-dependent tumor growth.
