Steroids and Derivatives

Tasimelteon (BMS-214778) is a melatonin receptor agonist that is used for the treatment of non-24 hour sleep-wake disorder in blind individuals.

Applications Eplerenone 7-Carboxylic Acid is an impurity of Eplerenone (E588775). Eplerenone is a 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. References de Gasparo, M., et al.: J. Pharmacol. Exp.

Applications Spironolactone-d3 is the labeled analogue of Spironolactone (S683000), a synthetic 17-lactone steroid which is a renal competitive aldosterone antagonist in a class of pharmaceuticals called potassium-sparing diuretics, used primarily to treat ascites in patients with liver disease, low-renin hypertension, hypokalemia, and Conn’s syndrome.

Prednisolone acetate (Omnipred) is the acetate salt form of prednisolone, a synthetic glucocorticoid with anti-inflammatory and immunomodulating properties.

Nicotinamide riboside increases NAD[+] levels and activates SIRT1 and SIRT3, culminating in enhanced oxidative metabolism and protection against high fat diet-

Fluorometholone delta 9,11 is a drug product that is used as an analytical reference standard for the quantitative determination of impurities in drugs. It is a natural metabolite and impurity in synthetic drugs such as fluoroquinolones and corticosteroids. Fluorometholone delta 9,11 has been shown to be a substrate for CYP3A4 and P-glycoprotein. This drug has also been shown to have anti-inflammatory effects and may decrease the risk of infection by suppressing neutrophil function.
