Biological Activity

Description EPI-001 is an androgen receptor N-terminal domain antagonist with IC50 of ∼6 μM and a selective PPAR-gamma modulator.
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 Research:[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 Research:[1]
  • Animal Models: Male mice bearing LNCaP s.c. xenografts
  • Dosages: 50 mg/kg
  • Administration: i.v.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
