Betamethasone (also called NSC-39470; SCH-4831; NSC39470; SCH4831) is a glucocorticoid steroid and an approved medication with moderate anti-inflammatory and immunosuppressive activities. Betamethasone has shown the inflammatory response by the betamethasone-receptor complex modulated the activity of certain genes, altering the production and activity of proteins. Betamethasone has been reported to inhibit the expression of these enzymes results in reduced production of such inflammatory mediators as prostaglandins, leukotrienes and nitric oxide.
| ln Vitro |
In L929 cells, betamethasone (0.1–1 μM; 12 h) increases gene expression[4]. The apoptosis of CEM C7 T-cells is induced by betamethasone (0.1–1 μM; 48 h)[4].

| ln Vivo |
Because betamethasone (0.48 mg; IVGT for 48 hours) reduces cerebral vasodilatation, it lessens the increase in CBF caused by hypercapnia[1]. Topical administration of betamethasone (0.05 ml; 1 mg/L) lowers activation of NF-κB, elevates TNFα and IL-1β, and stimulates the expression of IL-10 in the rats brain, all of which are caused by mechanical allodynia and thermal hyperalgesia induced by spinal nerve transection[2].

| Animal Protocol |
Animal/Disease Models: Rambouillet-Colombia ewes bred on a single occasion are received hypercapnic challenges[1]
Doses: 0.48 mg Route of Administration: Injected into the fetal jugular vein at a rate of 1 ml/h (10 μg betamethasone/h) and maintained over the next 48 h. Experimental Results: diminished cerebral blood flow (CBF) in all brain regions measured except the hippocampus after 24 h of infusion. The reduction in CBF was diminished to about 25-30 % after 48 h of infusion. |

Solubility in Formulation 1: ≥ 2.5 mg/mL (6.37 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.37 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (6.37 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
