Dexamethasone (Dex) is a potent and long-acting glucocorticoid in terms of anti-inflammatory activity without substantial sodium retaining effect. Here, we examine the ability of the 11beta-hydroxyglucocorticoids Dex and cortisol and their 11-keto forms 11-ketodexamethasone (11-ketoDex) and cortisone to bind to glucocorticoid receptors (GR) and mineralocorticoid receptors (MR) and to mediate nuclear translocation and transactivation of a reporter-gene. Unlike cortisone, the 11-ketosteroid 11-ketoDex acts as a potent GR agonist, comparable to Dex and cortisol. Transactivation of MR by Dex or 11-ketoDex was weak or undetectable, despite efficient binding and induction of nuclear translocation. 11beta-HSD2 protects MR and GR from inappropriate occupation by cortisol; it is, however, unable to prevent activation of GR by 11-ketoDex. The finding that 11-ketoDex is a specific GR agonist may explain the potent glucocorticoid effect of Dex in tissues expressing 11beta-HSD2 including kidney and colon and also in certain tumor cells.
