Dexamethasone is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects. Dexamethasone induces autophagy and mitophagy. Dexamethasone is tested in hospitalized patients with COVID-19 and is found to have benefits for critically ill patients.

In Vitro
In vitro	Dexamethasone results in decrease in transmonolayer paracellular permeability mainly to sucrose, fluorescein and dextrans of up to 20 KDa in an immortalised rat brain endothelial cell line (GPNT). Dexamethasone results in filamentous actin and the cytoskeleton associated protein cortactin being highly concentrated in the regions of cell-cell contact with few F-actin stress fibres visible within the cytoplasm in cultured rat brain endothelial cells, an observation consistent with a more differentiated barrier phenotype induced by dexamethasone. Dexamethasone treatment has been shown to strongly stimulate the level of the Id-1 protein, which is a serum-inducible helix-loop-helix transcriptional repressor, involved in cell differentiation, and this effect was shown to be associated with reorganisation of ZO-1 to the cell periphery in Con8 mammary epithelial tumor cells. Dexamethasone prevents cytokine-induced enhanced expression of MMP-9 and alterations in the expression of ZO-1 in untreated GPNT monolayers. ^[1] Dexamethasone depletes both basal and TNF-alpha-stimulated GSH levels by down-regulating the gamma-GCS-heavy subunit transcription via a mechanism involving AP-1 (c-Jun) in alveolar epithelial cells. Dexamethasone decreases both basal and stimulated GSH levels (TNF-α-treated) in alveolar epithelial cells (A549), without any change in GSSG. ^[2]

In Vivo
In Vivo	Dexamethasone is administered i.m. to pregnant ewes, leads to the following results (1) blood pressure is unchanged; (2) as previously reported in the fetus, sensitivity to endothelin-1 (ET) is increased; (3) acetylcholine-induced relaxation is increased; (4) L-NAME suppressible vasodilatory response to ET is abolished; (5) there is no change in endothelium-independent vasodilatation; and (6) there is no change in eNOS RNA and protein levels, when compared to saline treated controls. ^[3]

よくある質問（FAQ）

質問1:
I'm loonkig for Dexamethasone to use in cell culture, would it be better to use the Dexamethasone S1322, the sodiume phosphate S4028 or the acetate S3124?

回答
S1322 is the free base form of Dexamethasone, S4028 is the sodium phosphate form and S3124 is the acetate salt. All of them have similar biological activity in tissue culture, however, their suitabilities vary in different solvents. As free base, S1322 has high solubility in DMSO (79mg/ml), poor solubility in water (<1mg/ml), and moderate solubility in ethanol (6mg/ml). As sodium phosphate salt, S4028 has high solubility in water (103mg/ml) but is insoluble in DMSO and ethanol (<1mg/ml). The solubility of S3124 is 87mg/ml in DMSO, <1mg/ml in water, and 20mg/ml in ethanol. Selection can be made based on the customer's experimental setup.
