    Description: Spironolactone (SC9420; SC-9420; SC 9420; Spiresis; Spiridon) is a potent androgen receptor/AR antagonist with potential antineoplastic activity. It inhibits AR with an IC50 of 77 nM. Spironolactone has been approved for the treatment of fluid build-up caused by heart failure, liver scarring, or kidney disease. It can also be used to treat high blood pressure, low blood potassium that does not improve with supplementation, early puberty, excessive hair growth in women, and as a component of hormone replacement therapy for trans women.

    In Vitro

    In vitro activity: Spironolactone is a strong AR antagonist (IC50 ~ 77 nM), a weak GR antagonist (IC50 ~ 2.4 μM), and a weak PR agonist (EC50 ~ 740 nM). Spironolactone inhibits androstanolone binding in rat prostate nuclei and androstanolone specific binding in rat prostate cytosol.

    In VivoSpironolactone (1 mg/day) exerts anti-androgenic activity in rats. A single pretreatment of spironolactone (1 mg/rat) inhibits specific and saturable uptake of hormone into prostate induced by tracer dose administration of [3H]testosterone.
