AZD2906, a selective glucocorticoidreceptor (GR) agonist, demonstrates inhibitory concentrations (IC50s) of 2.2 nM in human GR, 0.3 nM in rat peripheral blood mononuclear cells (PBMC), 41.6 nM in humanwholeblood, and 7.5 nM in rat wholeblood, respectively[1]. Additionally, it induces an increase in micronucleated immature erythrocytes within rat bone marrow.
