Eplerenone Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Eplerenone is a mineralocorticoid receptor antagonist. It is selective for the mineralocorticoid receptor over glucocorticoid, androgen, progesterone, and estrogen receptors in radioligand binding assays (IC
50s = 138, 6,920, 523, >10,000, and 5,702 nM, respectively). Eplerenone inhibits aldosterone-induced mineralocorticoid activity in a luciferase assay (IC
50 = 122 nM).
In vivo, eplerenone (100 mg/kg per day) reduces urinary albumin secretion and glomerulosclerosis in the Dahl salt-sensitive rat model of hypertension and nephropathy. It reduces myocardial IL-1β levels and collagen deposition, as well as improves left ventricular systolic dysfunction in a mouse model of acute myocardial infarction. Formulations containing eplerenone have been used in the treatment of hypertension and heart failure after myocardial infarction.
Chemische Eigenschaften
White Solid
Verwenden
Selective aldosterone receptor antagonist (SARA), structurally similar to Spiranolactone. Eplerenone is used alone or in combination with other medications to treat high blood pressure. Eplerenone is in a class of medications called mineralocorticoid receptor antagonists. It works by blocking the action of aldosterone, a natural substance in the body that raises blood pressure.
Allgemeine Beschreibung
Eplerenone, 9,11α-epoxy-17α-hydroxy-3-oxopregn-4-ene-7α,21-dicarboxylic acid, γ-lactone,methyl ester (Inspra), is a newer aldosterone antagonist that isused for the treatment of hypertension.
Biologische Aktivität
Selective mineralocorticoid (aldosterone) receptor antagonist (IC 50 = 360 nM). Displays > 27-fold selectivity over androgen, progesterone and estrogen receptors (IC 50 > 10 μ M). Orally active antihypertensive in vivo .
Clinical Use
A newer drug, eplerenone, has a structure similar to that of spironolactone and a similar mechanism of action. It was initially approved for use in the treatment of
hypertension but it can now be used in the treatment of patients with left ventricular systolic dysfunction and congestive heart failure after myocardial infarction.
