Used in research to modulate glucocorticoid receptor activity, enabling studies on anti-inflammatory pathways and immune response regulation. Its phosphate group enhances cellular uptake, while the Gly-Glu-Br moiety supports targeted delivery and receptor binding. Commonly applied in assays investigating steroid signaling, inflammation models, and metabolic effects in cell cultures. Also explored for prodrug development due to its cleavable dipeptide structure, allowing controlled release of active glucocorticoid agents.
