产品描述:
Ciclesonide-d7 is intended for use as an internal standard for the quantification of ciclesonide (CIC; Item No. 18227) by GC- or LC-MS. Ciclesonide is a prodrug form of the glucocorticoid receptor agonist desisobutyryl-CIC (des-CIC).{29504} CIC binds to the glucocorticoid receptor with a Ki value of 37 nM.{29502} It is selective for the glucocorticoid receptor over the estrogen, progesterone, and testosterone receptors. CIC inhibits eosinophil influx into the lung (ED50 = 0.49 mg/kg) and reduces sephadex-induced lung edema (ED50 = 0.72 mg/kg) in a rat model of ovalbumin-sensitized and -challenged airway inflammation. Formulations containing CIC have been used in the maintenance treatment of asthma and in the treatment of allergic rhinitis.
