  • Active Stat5a/b increases nuclear levels of antiandrogen-liganded AR in PC-3 cells. PC-3 cells were infected with AdAR, AdPrlR and AdWTStat5a, serum-starved for 12 h, and pretreated with 1 nM DHT, 10 μM Bicalutamide (Bic), 10 μM Flutamide (Flu) or 10 μM MDV3100 (MDV) for 1 h before stimulation with 10 nM Prl for 30 min, where indicated. Immunostaining depicts DAPI, Stat5a/b, AR and merged imaging of Stat5a/b and AR.

Biological Activity

Description Flutamide (SCH-13521) is an antiandrogen drug, with its active metablolite binding at androgen receptor with Ki values of 55 nM, and primarily used to treat prostate cancer.
Androgen Receptor [1]
55 nM(Ki)
In vitro

Flutamide (Eulexin) is an antiandrogen drug. Flutamide-OH, the active metabolite of flutamide, directly binds at rat anterior pituitary androgen receptor with Ki values of 55 nM. [1] Flutamide does not affect the proliferation of an androgen-sensitive clone of the mouse mammary carcinoma Shionogi SC-l 15 cells in culture, shows only antiandrogenic effect, but not androgenic effect. [2] Flutamide provides treatment for prostate cancer when used along with leuprolide. [3]

In vivo Flutamide causes a markedly reduction in rat ventral prostate weight from 319 mg to 245 mg. A combination of flutamide and LHRH agonist induces an additive effect with a decrease in prostate weight to 101 mg, and an marked drop in prostatic ODC activity. [4]


Kinase Assay:[1]
- Collapse

Androgen Receptor Assay:

Aliquots of 100 μl cytosol are incubated at 0-4°C for 18 h with 100 μl of the indicated saturating concentration of [3H]T in the presence or absence of increasing concentrations of nonlabeled T, DHT, flutamide (FLU) or flutamide-OH (FLU-OH). At the end of the incubation, free and bound T are separated by the addition of 200 μl dextran-coated charcoal (1 % charcoal, 0.1% dextran T-70, 0.1% gelatin, 1.5 mM EDTA and 50 mM Tris (pH 7.4)) for 15 min before centrifugation at 2300 × g for another 15 min at 0-4°C. Aliquots (350 μl) of the supernatant are transferred to scintillation vials with 10 ml of an aqueous counting solution before counting in a Beckman LS 330 counter.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
