EPI-001 is a small-molecule inhibitor of androgen receptor N-terminal domain. EPI-001 could target the amino terminal domain of the AR and inhibit the protein-protein interactions which are necessary for AR transcriptional activity. The androgen receptor (AR) is involved in mediating the actions of male sex steroids. Amplification and over-expression of androgen receptor gene may result in hormone-refractory prostate cancer [1].
In vitro: EPI-001 inhibited the ligand-dependent ARGal4 transcriptional activity in LNCaP cells and the ligand-independent ARGal4 transcriptional activity in the CRPC C4-2 cell line. In a panel of cell lines, EPI-001 treatment decreased the mRNA expression level of AR protein after 8 and 16 h treatment, such as androgen sensitive PCa, CRPC, LNCap, C4-2, and LAPC4 cell line. EPI-001 dose-dependently inhibited the PCa/CRPC cell growth [2].
In vivo: Intravenous injection of EPI-001 significantly reduced the weight of benign prostates and blocked the growth of prostate cancer xenograft from noncastrated mature mice. EPI-001 caused tumor regression of CRPC. In male mice bearing LNCaP xenografts, after treated with EPI- 001 by i.v. injection for 2 weeks, the tumor size was less than half of the control group [3].
