Common Name2-hydroxyflutamide
ClassSmall Molecule
Description2-hydroxyflutamide is a metabolite of flutamide. Flutamide is an oral nonsteroidal antiandrogen drug primarily used to treat prostate cancer. It competes with testosterone and its powerful metabolite, dihydrotestosterone (DHT) for binding to androgen receptors in the prostate gland. By doing so, it prevents them from stimulating the prostate cancer cells to grow. Flutamide has been largely replaced by a newer member of this class, bicalutamide, due to a better side-effect profile. (Wikipedia)

Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityHydroxyflutamide is an antiandrogen. Antiandrogens alter the androgen pathway by blocking the appropriate receptors, competing for binding sites on the cell's surface, or affecting androgen production. Antiandrogens are classified as steroidal or nonsteroidal. Steroidal antiandrogens not only counter androgens, but also affect secondary sex characteristics. Steroidal antiandrogens directly affect gene expression due to their fat-soluble nature that allows them to diffuse through the plasma membrane's phospholipid bilayer and prevent the binding of testosterone and dihydrotestosterone (DHT) to the androgen receptor. Inhibition of androgen production occurs through a unique mechanism for each antiandrogen. (Wikipedia)

Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesIn men, antiandrogens are most frequently used to treat prostate cancer. In women, antiandrogens are used to decrease levels of male hormones causing symptoms of hyperandrogenism. (Wikipedia)
Minimum Risk LevelNot Available
Health EffectsEnvironmental antiandrogens can have harmful effects on reproductive organ development in fetuses exposed in utero as well as their offspring. (Wikipedia)
