Description

Apalutamide (ARN-509) is a potent and competitive androgen receptor (AR) antagonist, binding AR with an IC50 of 16 nM[1].

IC50 & Target

IC50: 16 nM (Androgen receptor)[1]
In Vitro

Apalutamide (ARN-509) also exhibits low micromolar affinity (IC50 3 μM) for the GABAA receptor in radioligand binding-assays and thus may potentially antagonize GABAA at therapeutic dose levels[1]. Apalutamide is a potent androgen receptor (AR) antagonist that targets the AR ligand-binding domain and prevents AR nuclear translocation, DNA binding, and transcription of AR gene targets[2].

In Vivo

Apalutamide (ARN-509) exhibits low systemic clearance, high oral bioavailability and long plasma half-life in both mouse and dog, supporting once-daily oral dosing. Consistent with its long terminal-half-life, Apalutamide steady-state plasma-levels increases in repeat-dose studies, resulting in high C24hr levels and low peak:trough ratios (ratio:2.5). Castrate male mice bearing LNCaP/AR xenograft tumors are treated with either Apalutamide at doses of 1, 10 or 30 mg/kg/day. Thirteen of 20 Apalutamide (30 mg/kg/day)-treated animals exhibit >50% reduction in tumor-volume at day 28 versus 3 of 19 MDV3100 (30 mg/kg/day)-treated mice[1].

Cell Assay
[1]

Trypsinized VCaP cells are adjusted to a concentration of 100,000 cells per mL in phenol-red-free RPMI 1640 (with 5% CSS), and dispensed in 16 µL aliquots into CellBIND 384 well plates. Cells are incubated for 48 hours, after which ligand is added in a 16 µL volume to the RPMI culture medium. For the antagonist mode assay, the ligands are diluted in culture medium also containing 30 pM R1881. After 7 days’ incubation, 16 µL of CellTiter-Glo Luminescent Cell Viability Assay is added and Relative Luminescence Units (RLUs) measured[1].

Animal Administration
[1]

Mice[1]
In vivo xenograft experiments to determine anti-tumor response are carried out in SHO SCID male mice. Mice are orchiectomized under isoflorane anesthesia and are given 2-3 days to recover prior to tumor cell injection. LNCaP/AR(cs) cells are suspended in 50% RPMI, 50% Matrigel, and 5×106 cells/xenograft are injected in a volume of 100 μL. Animals are observed weekly until tumor growth is apparent. From 24 d post-injection, tumors are measured weekly, and after 40-60 days post-injection, animals are randomized into cohorts of equivalent mean (150-250 mm3) and range tumor burden. All compounds (e.g., Apalutamide, 30 mg/kg per day) are administered daily by oral gavage. Statistical analyses are performed using Graphpad Prism.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
