产品描述:
Spironolactone-d3 is intended for use as an internal standard for the quantification of spironolactone by GC- or LC-MS. Spironolactone is a steroidal mineralocorticoid receptor antagonist (IC50 = 24 nM) and a diuretic.{68137} It is selective for the mineralocorticoid receptor over the glucocorticoid receptor (IC50 = 2,410 nM) but also binds to the androgen receptor and progesterone receptor (IC50s = 77 and 743 nM, respectively). In vivo, spironolactone (37.5 mg/kg per day) administered in combination with lisinopril preserves ejection fraction in mice and reduces myocardial fibrosis in a mouse model of Duchenne muscular dystrophy (DMD).{51580} Formulations containing spironolactone have been used in the treatment of hypertension and heart failure.
