White powder. Soluble in DMSO (20mg/ml) or DMF (20mg/ml). Chemical. CAS: 80474-14-2. Formula: C25H31F3O5S. MW: 500.57. Fluticasone propionate is a synthetic corticosteroid. It is a high affinity, selective glucocorticoid receptor agonist (Kd = 0.5nM). It is used as an anti-inflammatory agent for asthma. It has low systemic bioavailability and has been investigated for effectiveness as an inhaled or intranasal corticosteroid to reduce airflow obstruction related to asthma, allergic rhinitis and other airway diseases. It potently stimulates glucocorticoid receptor-mediated transactivation of gene expression and enhances human eosinophil apoptosis in vitro. It also potentiates KV1 channels (EC50 = 37nM).
