Mechanism of Action

Targets/IC₅₀/Ki	Androgen receptor 11 nM(Ki)
In vitro	In AR-HEK293 cells stably expressing full-length hAR, Darolutamide (ODM-201) inhibits human AR (hAR) with IC50 of 26 nM. It inhibits VCaP cell proliferation with IC50 of 230 nM, while has no effect on the viability of AR-negative cell lines tested, DU-145 prostate cancer cells and H1581 lung cancer cells.
Kinase Assay	AR binding affinity
Kinase Assay	AR binding affinities of test compounds, including Darolutamide (ODM-201), are studied in cytosolic lysates obtained from ventral prostates of castrated rats by a competition binding assay. Fresh prostates are minced and homogenized with Buffer A containing protease inhibitors. The homogenates are centrifuged and the resultant supernatants are treated with a dextran-coated charcoal solution to remove endogenous steroids. The dissociation constant of the radio ligand [³H]mibolerone for isolated rat ARs is determined in a saturation binding experiment. For the determination of Ki values, prostate cytosol preparations and 1 nM [³H]mibolerone are incubated with increasing concentrations of test compounds overnight. After the incubation, bound and free steroids are separated by treatment with 100 μL of dextran-coated charcoal suspension. Bound radioactivity is determined by counting 100 μL of supernatant fraction in 200 μL of scintillation fluid using a microbeta counter. All procedures are carried out at 0–4 °C.
In vivo	In mice bearing VCaP xenografts, Darolutamide (ODM-201) (50 mg/kg, p.o.) significantly inhibits castration-resistant prostate tumor growth.
