Methylprednisolone (NSC-19987) 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] |

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] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
