Dexamethasone phosphate disodium
Based on 12 publication(s) in Google Scholar
Dexamethasone phosphate (Dexamethasone 21-phosphate) disodium is a prodrug form of the glucocorticoid Dexamethasone (HY-14648). Dexamethasone phosphate disodium is produced by introducing a phosphate ester group at the 21-position of the Dexamethasone molecule, forming a salt with sodium ions, thereby significantly improving water solubility. Dexamethasone phosphate disodium 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 disodium inhibits the secretion of RANTES, TGF-β1 and NO, promotes the production of MIP-1α and IL-10, and blocks microglial migration. Dexamethasone phosphate disodium is almost completely converted to Dexamethasone in rat blood, and supports transdermal delivery via iontophoresis. Dexamethasone phosphate disodium can be used in research related to steroid-dependent ulcerative colitis, chemotherapy-induced vomiting, allergic asthma and acute colitis (inflammatory bowel disease).

Biological Activity
Glucocorticoid receptor[1]
Dexamethasone phosphate disodium (1, 2, 4 μM; 23 h) does not induce cytotoxicity in BV-2 microglial cells[1].
Dexamethasone phosphate disodium (1, 2, 4 μM; 3 h pre-incubation, followed by 24 h LPS co-incubation) dampens LPS-induced secretion of RANTES, TGF-β1, and NO in BV-2 microglial cells, while dexamethasone phosphate disodium (4 μM; 24 h incubation alone) has no inhibitory effect on these mediators[1].
Dexamethasone phosphate disodium (4 μM; 3 h pre-incubation, followed by 24 h LPS co-incubation) increases LPS-reduced production of IL-10 and MIP-1α in BV-2 microglial cells, while dexamethasone phosphate disodium (4 μM; 24 h incubation alone) reduces IL-10 production in untreated BV-2 microglial cells[1].
Dexamethasone phosphate disodium (4 μM; 3 h pre-incubation in lower chambers, followed by 18 h LPS co-incubation) mitigates LPS-induced migration of BV-2 microglial cells, while having no effect on migration of untreated BV-2 microglial cells when used at 4 μM for 18 h incubation alone[1].
Dexamethasone phosphate disodium (1, 2, 4 μM; 3 h pre-incubation, followed by 30 min LPS co-incubation) ameliorates LPS-induced degradation of IRAK-1 and IRAK-4, and inhibits LPS-induced activation of TRAF6, p-TAK1, and p-JNK in BV-2 microglial cells[1].
Dexamethasone phosphate disodium (5×10-6 M; 5-min intervals at 37°C) undergoes hydrolysis to Dexamethasone free alcohol in human whole blood in vitro with a first-order rate constant of 0.162 hr-1, which is 25-fold slower than its in vivo conversion rate[3].
Dexamethasone phosphate disodium (200 μM; 7 h) shows good stability with limited hydrolysis when incubated with human, porcine, or rat dermis for 7 hours, with 72.5-82.2% of the prodrug remaining intact[4].
Dexamethasone phosphate disodium (50.8-51.8% drug loading; heated at 20 °C min-1) intercalated into MgAl layered double hydroxides enhances the thermal stability of dexamethasone phosphate disodium, with its decomposition occurring at temperatures higher than those of free sexamethasone phosphate disodium[5].
Dexamethasone phosphate disodium (50.8-51.8% drug loading) is successfully intercalated into MgAl layered double hydroxides via electrostatic interactions, with no denaturation of the drug molecules, as confirmed by preserved characteristic FT-IR bands and shifted phosphate group vibrations[5].
Dexamethasone phosphate disodium (1.5 mg/mL; 50 hours) is efficiently encapsulated by the NPA2 coacervate, which mediates sustained release of the drug over 50 hours in a cell-free in vitro system[6].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Dexamethasone phosphate disodium (0.25 mg/kg; i.p.; daily; 8 days) reduces asthma-related inflammation, cytokine production, and airway hyperresponsiveness in OVA-induced allergic asthma rats[5].
Dexamethasone phosphate disodium (1.15 mg; p.o.; on days 1, 3, and 5) loaded in NPA2 coacervate significantly reduces DSS-induced acute colitis severity (mean histopathology score 0.500), restores gut barrier function and microbiota diversity, and maintains low, sustained systemic drug exposure[6].
