一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Ciclesonide is a prodrug of the potent glucocorticoid receptor agonist desisobutyryl-ciclesonide. Ciclesonide undergoes the hydrolysis process by ester cleavage at the C21 position to desisobutyryl-ciclesonide, followed by reversible formation of fatty acid esters in lung cells. Although both ciclesonide and desisobutyryl-ciclesonide are able to bind to the glucocorticoid receptor, the active metabolite desisobutyryl-ciclesonide (IC50 = 210 nM) is about 100-fold more potent than the parent compound ciclesonide (IC50 = 1.75 nM). Formulations containing ciclesonide have been used in the maintenance treatment of asthma and in the treatment of allergic rhinitis.

Cell experiment:[2] | |
Cell lines | Normal human bronchial epithelial (NHBE) cells |
Reaction Conditions | 5 μM ciclesonide for 24 h incubation |
Applications | Ciclesonide (5 μM) was rapidly hydrolyzed to desisobutyryl-ciclesonide by NHBE cells (approximately 30% conversion within the first 4 h), and 96% conversion of ciclesonide to desisobutyryl-ciclesonide was achieved at 24 h. |
Animal experiment:[3] | |
Animal models | Ovalbumin-sensitized and challenged Brown Norway rats |
Dosage form | 0 ~ 10 mg/kg Administered by the intratracheal route into the airways 24 and 1 h before exposure to inhaled antigen |
Applications | Ciclesonide dose-dependently suppressed the antigen-induced influx of eosinophils into the airway lumen, with an ED50 value of 0.75 mg/kg. Moreover, ciclesonide significantly inhibited eosinophil influx into the lung tissue, with an ED50 value of 0.49 mg/kg. |
