Protocol

Cell experiment [1]:

Cell lines

LNCaP, LNCaP-AR and VCaP cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

1 μM; 48 hrs

Applications

In LNCaP, LNCaP-AR and VCaP cells, ARN-509 increased DNA damage. In LNCaP cell line, ARN-509 decreased cell survival. In addition, ARN-509 significantly decreased C-NHEJ-mediated recombination (> 60%) in LNCaP cells that had been transfected with V(D)J recombination substrate along with RAG1 and RAG2 expression vectors.

Animal experiment [2]:

Animal models

Castrate male immunodeficient mice harboring LNCaP/AR-luc xenograft tumors

Dosage form

10 mg/kg/d; p.o.; for 17 days

Applications

In castrate male immunodeficient mice harboring LNCaP/AR-luc xenograft tumors, the 17-day Oral treatment with ARN-509 (10 mg/kg/d) consistently reduced androgen-driven luciferase reporter-gene activity. In addition, ARN-509 decreased the proliferative index and increased the apoptotic rate of tumors, respectively.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

ARN-509, a synthetic biaryl thiohydantoin compound, is a competitive androgen receptor (AR) inhibitor and fully antagonistic to AR overexpression. The IC50 of ARN-509 is 16 nmol/L [1].
AR, included in the steroid receptor superfamily, is important for prostate cell proliferation and male sexual differentiation [2]. AR overexpression is a common and important feature of castration resistant prostate cancer (CRPC) [1].
ARN-509 (1 μmol/L) treatment for 48 hours resulted in increased DNA damage in LNCaP cells, LNCaP-AR cells and VCaP cells. In LNCaP cell line, treatment with ARN-509 (1 μmol/L) resulted in decreased cell survival. Treatment with ARN-509 (1 μmol/L) for 48 hours significantly decreased C-NHEJ–mediated recombination (>60%) in LNCaP cells that had been transfected with V(D)J recombination substrate along with RAG1 and RAG2 expression vectors [3]. ARN-509 showed robust transcriptional and proliferative agonist activity in AR F876L–expressing cells, and promoted AR DNA binding in LNCaP/SRαF876L cells [4].
Orally treated with ARN-509 (10 mg/kg/d) for 17 days, androgendriven luciferase reporter–gene activity in castrate male immunodeficient mice harboring LNCaP/AR-luc xenograft tumors (coexpressing exogenous AR and the AR-dependent reporter ARR2-Pb-luc), was consistently reduced. This indicated that ARN-509 inhibited AR in vivo. ARN-509 made tumors exhibit a decrease in proliferative index and an increase in apoptotic rate [1].
