NCIt definition : A toluidine derivative and a nonsteroidal antiandrogen that is structurally related
to bicalutamide and nilutamide. Flutamide and its more potent active metabolite 2-hydroxyflutamide
competitively block dihydrotestosterone binding at androgen receptors, forming inactive
complexes which cannot translocate into the cell nucleus. Formation of inactive receptors
inhibits androgen-dependent DNA and protein synthesis, resulting in tumor cell growth
arrest or transient tumor regression. (NCI04);
Alternative definition : NCI-GLOSS: An anticancer drug that is a type of antiandrogen.;
