Biological Activity: Dexamethasone phosphate (Dexamethasone 21-phosphate) is a prodrug form of the glucocorticoid Dexamethasone (HY-14648). Dexamethasone phosphate is prepared by introducing a phosphate ester group to the hydroxyl group at position 21 of the Dexamethasone molecule. Dexamethasone phosphate inhibits LPS (HY-D1056)-induced degradation of IRAK-1 and IRAK-4, and blocks LPS-induced activation of TRAF6, p-TAK1 and p-JNK. Dexamethasone phosphate inhibits the secretion of RANTES, TGF-β1 and NO, promotes the production of MIP-1α and IL-10, and blocks microglial migration. Dexamethasone phosphate is almost completely converted to Dexamethasone in rat blood, and supports transdermal delivery via iontophoresis. Dexamethasone phosphate can be used in research related to steroid-dependent ulcerative colitis, chemotherapy-induced vomiting, allergic asthma and acute colitis (inflammatory bowel disease)[1][2][3][4][5][6].
