The active metabolite of Flutamide, is Flutamide-OH. Both of them directly bind rat anterior pituitary androgen receptor (Ki=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].
Flutamide has cytotoxic activity against PC3 and LNCap (IC50s 20 μM and 12 μM, respectively). Flutamide (10 μM, 5 μM; 48 h) induces apoptosis and reduces cell migration and colonization in PC3 and LNCap cells[4].
Flutamide also downregulates the expression of KLK2 and EMT pathway genes in cells[4].

Flutamide (12.5-50 mg/kg; sc; once daily for 3 days) alleviates heat stroke in heat-stressed mice[6].
