产品描述:
Dexamethasone-d4 is intended for use as an internal standard for the quantification of dexamethasone (Item No. 11015) 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 nM versus 17 nM, respectively).{20150} Through receptor activation, dexamethasone has both transactivating and transrepressing effects on gene expression, producing, in general, anti-inflammatory results.{20149}
