Biological Activity

Description EPI-001 is an androgen receptor N-terminal domain antagonist with IC50 of ∼6 μM and a selective PPAR-gamma modulator.
Targets
PPARγ [2] Androgen Receptor [1]
(in LNCaP cells)
~6 μM
In vitro EPI-001 blocks transactivation of the AR NTD, interacts with the AF-1 region, inhibits protein-protein interactions with AR, and reduces AR interaction with androgen-response elements on target genes. In LNCaP cells, EPI-001 inhibits both androgen-dependent and androgen-independent (OCM-induced) cell proliferation. [1] In LNCaP cells, EPI-001 also acts as a PPAR-gamma modulator to result in inhibition of androgen receptor expression and activity, which inhibits prostate cancer growth. [2]
In vivo In male mice bearing CRPC LNCaP s.c. xenografts, EPI-001 (50 mg/kg, i.v.) blocks the androgen-axis and inhibits androgen-dependent tumor growth by reducing proliferation and increasing apoptosis. [1]

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    LNCaP cells

  • Concentrations

    10 μg/mL

  • Incubation Time

    4 days

  • Method

    LNCaP cells are treated with bicalutamide (BIC) or EPI-001 for 1 hr before the addition of R1881 (0.1 nM) for 4 days. LNCaP cells are treated with OCM (50%) with, or without, EPI-001 for 3 days (serum-free, androgen-free, phenol red-free conditions).
Animal Study:[1]
  • Animal Models

    Male mice bearing LNCaP s.c. xenografts

  • Dosages

    50 mg/kg

  • Administration
