    Product Description

    Apararenone is a non-steroidal mineralocorticoid receptor antagonist (Ki = 0.104 µM for the human receptor).1 It is selective for mineralocorticoid receptors over estrogen receptor α (ERα) and ERβ and glucocorticoid, progesterone, and androgen receptors (IC50s = >100 µM for all). Apararenone increases the urinary ratio of sodium to potassium in adrenalectomized rats in a dose-dependent manner. It inhibits aldosterone- and nephrectomy-induced increases in systolic blood pressure and urinary albumin levels, as well as myocardial necrosis and fibrosis, cardiac arterial degeneration, and renal tubule damage, in a rat model of renal hypertension when administered at doses of 3 or 10 mg/kg per day.

    WARNING This product is not for human or veterinary use.
