Description
Cyproterone acetate (CPA) is a synthetic steroid that acts as an antagonist/partial agonist of the androgen receptor (IC50 = 26 nM in humans). Androgen receptor antagonists such as CPA have been shown to have clinical use in androgen-dependent conditions such as prostate cancer, hirsutism, and alopecia. However, high doses of CPA (10 mg/animal/day) can suppress accessory sexual glands and fertility in adult male rats. CPA promotes hepatomitogenic activity and has been reported to induce apoptosis of hepatocytes in rats at 0.3 μM after 72 hours exposure.Related product price
