| Bioactivity | Ciclesonide (RPR251526) is a glucocorticoid with an potent anti-inflammatory activity. Ciclesonide can be used for asthma research[1]. | ||||||||||||
| Invitro | Ciclesonide, the parent compound, undergoes hydrolysis by ester cleavage at the C21 position to the active metabolite, desisobutyryl-ciclesonide (des-CIC), followed by reversible formation of fatty acid esters within the lung cells. Ciclesonide (5 μM) is rapidly hydrolyzed by normal human bronchial epithelial (NHBE) cells (approximately 30% conversion at 4h), with almost complete conversion by 24 h[1]. | ||||||||||||
