Background:
Dexamethasone-d4is intended for use as an internal standard for the quantification of dexamethasone by GC- or LC-MS. Dexamethasone is a synthetic glucocorticoid that binds the human glucocorticoid receptor with a higher affinity than a natural ligand, cortisol (Kd= 5 nMversus17 nM, respectively).1Through receptor activation, dexamethasone has both transactivating and transrepressing effects on gene expression, producing, in general, anti-inflammatory results.2
