Ciclesonide Chemical Properties,Uses,Production


Ciclesonide, a new inhaled corticosteroid (ICS), is indicated for the prophylactic treatment of persistent asthma. ICS treatment is a widely accepted standard of care for maintenance therapy of chronic asthma, and the currently available agents include fluticasone propionate, budesonide, triamcinolone acetonide, flunisolide, and beclomethasone dipropionate. These agents exert their potent anti-inflammatory effects via modulation of the glucocorticoid receptor (GR). Although ICS drugs are generally safe and well tolerated compared with oral corticosteroids, many have measurable systemic exposures, and concerns over potential side effects resulting from it severely limit the dose at which they can be administered for long-term therapy. Systemic adverse effects associated with corticosteroids include HPA axis suppression, osteoporosis, abnormal glucose metabolism, cataracts, and glaucoma, some of which could potentially occur with the long-term use of high dose ICS. The key differentiators for ciclesonide relative to other ICS drugs are its longer duration of action and lower systemic exposure. Ciclesonide is an isobutyryl ester prodrug. It is cleaved by the endogenous esterases in the lung to des-isobutyryl ciclesonide (des- CIC), which is a potent GR agonist. The binding affinity of des-CIC for human GR (Ki=0.31 nM) is similar to other ICS such as budesonide (Ki=0.44nM) and fluticasone propionate (Ki=0.24nM), while ciclesonide itself has about 100-fold lower affinity (Ki=37nM). In lung tissue, des-CIC undergoes reversible lipid conjugation to form oleate and palmitate ester conjugates, which act as a slow-release pool for the drug and increase the pulmonary residence time. This, in turn, contributes to the enhanced local effects and the long duration of action.
Inhaled ciclesonide was generally well tolerated in these clinical studies. Ciclesonide did not suppress biochemical markers of adrenal function in 52-week studies; however, the long-term (>52 weeks) systemic effects remain unknown. Ciclesonide is chemically produced via a semi-synthesis starting from 16-α-hydroxyprednisolone by first converting to a triisobutyryl ester intermediate with isobutyric anhydride, and subsequent reaction of the triester with cyclohexane carboxaldehyde and hydrochloric acid in dioxane. The latter step produces the cyclic ketal as a mixture of diastereomers, which is subjected to HPLC and fractional crystallization to produce ciclesonide.

General Description

Ciclesonide (Omnaris) is a prodrug that requireshydrolysis of the isobutyrate ester at C21 to form theactive corticosteroid (des-ciclesonide). It has minimal oralbioavailability due to extensive metabolism, mainly byCYP3A4. The metabolites of ciclesonide have not beenfully characterized.
