    Product Description

    RU-58841 is a non-steroidal antiandrogen that binds to the androgen receptor (Kd = 1.8, 1.1, 5.6, 1.3, and 1.4 nM for human, rat, mouse, hamster prostate, and hamster flank organ receptors, respectively).1 In vivo, topical administration of RU-58841 (1-100 μg per animal) reduces size of the flank organ without affecting sex organs in a dose-dependent manner in hamsters. It has no effect on sex organ weight in intact rats when administered percutaneously, subcutaneously, or orally at doses up to 1 mg per animal. RU-58841 (5% v/v) also induces hair regrowth in the bald frontal scalps of postpubertal stumptailed macaques, a model for male pattern baldness.2
