Background:

Desisobutyryl-ciclesonide is the active metabolite of Ciclesonide. Desisobutyryl-ciclesonide has affinity for the glucocorticoid receptor. Glucocorticoid receptor[1]


Ciclesonide, an inhaled corticosteroid with almost no affinity for the glucocorticoid receptor, is highly effective in downregulating in vitro pro-inflammatory activities of airway parenchymal cells when converted into the active metabolite Desisobutyryl-ciclesonide. Peripheral blood mononuclear cell proliferation to C. albicans is dose-dependently inhibited by 0.3-3.0 μM Ciclesonide and Desisobutyryl-ciclesonide but inhibition by Desisobutyryl-ciclesonide is higher. A significant proliferation to PhlP5 is observed only in cultures from atopic subjects: an effective downregulation is already detected at 0.03 μM Ciclesonide and 0.003 μM Desisobutyryl-ciclesonide (complete inhibition at 3 μM Ciclesonide and 0.03 μM Desisobutyryl-ciclesonide). 3 μM Ciclesonide and Desisobutyryl-ciclesonide reduce the PhlP5-specific T-cell blast proliferation and interleukin 4-producing cell proportion. In PBMCs cultures from atopic patients, both Ciclesonide (CIC) and Desisobutyryl-ciclesonide (des-CIC) induce a dose-dependent downregulation of PhlP5-induced proliferation. The effect is already significantat 0.03 μM Ciclesonide and at 0.003 μM Desisobutyryl-ciclesonide (pPhlP5-induced PBMC proliferation is higher for Desisobutyryl-ciclesonide than for Ciclesonide at 0.003 μM (p<0.05), 0.03 μM (p<0.001) and 0.3 μM (p<0.05)[1].
