Brilanestrant (ARN-810; GDC-0810) is an orally bioavailable selective estrogen receptor degrader (SERD) with IC50 of 0.7 nM.

IC50 & Target

IC50: 0.7 nM (estrogen receptor)

In Vitro

Brilanestrant (ARN-810; GDC-0810) is a potent ER-α binder (IC50=6.1 nM), a full transcriptional antagonist with no agonism (3× ERE, IC50=2 nM), and displays good potency and efficacy in ER-α degradation (EC50=0.7 nM) and MCF-7 breast cancer cell viability (IC50=2.5 nM) assays[1].Brilanestrant (ARN-810; GDC-0810) induces a distinct ERα conformation versus tamoxifen and other ER therapeutics, and does not exhibit tamoxifen-like ER agonism in MCF7 cells[2].

In Vivo

The pharmacokinetic profile of Brilanestrant (ARN-810) shows it is a olw clearance molecule across species, with good bioavailability (40%-60%). Brilanestrant (ARN-810) (3 mg/kg, p.o.) shows substantial tumor-growth inhibition in a tamoxifen-sensitive MCF-7 xenograft model, while at the highest dose of 100 mg/kg/day, all animals show tumor regression of more than 50% without weight loss[1].
Brilanestrant (ARN-810) exhibits low clearance (11 mL/min/kg) and 61% oral bioavailability. Brilanestrant (ARN-810) (1-100 mg/kg/day, p.o.) displays dose dependent efficacy in the MCF7 xenograft model[2].

Cell Assay

MCF-7 cells are adjusted to a concentration of 40000 cells per mL in RPMI containing 10% FBS and 20 mM HEPES. Then 16 μL of the cell suspension (640 cells) is added to each well of a 384-well plate, and the cells are incubated overnight to allow the cells to adhere. The following day a 10-point, serial 1:5 dilution of each compound is added to the cells in 16 μL at a final concentration ranging from 10 to 0.000005 μM. After 5 days' compound exposure, 16 μL of CellTiter-GLo is added to the cells, and the relative luminescence units of each well are determined. CellTiter-GLo added to 32 μL of medium without cells is used to obtain a background value. The percent viability of each sample is determined as follows: (RLU sample-RLU background/RLU untreated cells-RLU background ×100=%viability)

Animal Administration

Time release pellets containing 0.72 mg 17-β estradiol are subcutaneously implanted into nu/nu mice. MCF-7 cells are grown in RPMI containing 10% FBS at 5% CO2 37°C. Trypsinized cells are pelleted and resuspended in 50% RPMI(serum free)and 50% Matrigel at 1×107 cells/mL. MCF-7 cells are subcutaneously injected (100 μL/animal) on the right flank 2-3 days post pellet implantation. Tumor volume (length × width2/2) is monitored biweekly. When tumors reach an average volume of appr 200 mm3 animals are randomized and treatment is started. Animals are treated with vehicle or compound daily for 4 weeks. Tumor volume and body weight are monitored biweekly throughout the study.

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.
