Clear solution
5% DMSO 95% Corn oil
18.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 370 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.75mg/ml Taking the 1 mL working solution as an example, add 50 μL of 75 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Methylprednisolone (NSC-19987,U 7532) is a synthetic glucocorticoid receptor agonist, used to achieve prompt suppression of inflammation. Methylprednisolone activates ACE2 and reduces IL-6 levels, thus improves severe or critical COVID-19. Methylprednisolone markedly reduces autophagy and apoptosis.
in vitro

Methylprednisolone (2-10 mg/kg) markedly inhibits TNF production but does not affect serum levels of IL-10, while a high methylprednisolone dose (50 mg/kg) increases LPS-induced IL-10 levels. Methylprednisolone(from 0.01 to 100 mg/mL) also increases the biosynthesis of IL-10 by LPS-activated mouse peritoneal macrophages. [1]
in vivo

Methylprednisolone decreases RGC survival in rats with electrophysiologically diagnosed optic neuritis. Methylprednisolone decreases RGC survival by a nongenomic, calcium-dependent mechanism. Methylprednisolone-induced enhancement of RGC degeneration depends on calcium influx through voltage-gated calcium channels. [2] Methylprednisolone treatment leads to a significant decrease in the number of ED1-positive cells in both rostral and caudal stumps. Methylprednisolone treatment results in a significant reduction in tissue loss in both cord stumps at 2, 4 and 8 week post-injury. Methylprednisolone leads to a long-term reduction of ED1-positive cells and spinal tissue loss, reduced dieback of vestibulospinal fibres, and a transient sprouting of vestibulospinal fibres near the lesion at 1 and 2 weeks post-lesion. [3] Methylprednisolone at a dose of 30 mg/kg which has been shown to be effective in improving functional outcomes in rat SCI models, suppresses TNF-α expression and NF-kB activation. Methylprednisolone inhibition of NF-kB function is likely mediated by the induction of IkB, which traps NF-kB in inactive cytoplasmic complexes. [4]
