X-ray Crystal Structure of the Novel Enhanced-Affinity Glucocorticoid Agonist Fluticasone Furoate in the Glucocorticoid Receptor-Ligand Binding Domain.
J Med Chem. 2008 Jun 26;51(12):3349-52. Epub 2008 Jun 4.
An X-ray crystal structure is reported for the novel enhanced-affinity glucocorticoid agonist fluticasone furoate (FF) in the ligand binding domain of the glucocorticoid receptor. Comparison of this structure with those of dexamethasone and fluticasone propionate shows the 17alpha furoate ester to occupy more fully the lipophilic 17alpha pocket on the receptor, which may account for the enhanced glucocorticoid receptor binding of FF.
