Mechanism of Action

Targets/IC₅₀/Ki	Glucocorticoid receptor
In vitro	Methylprednisolone (2-10 mg/kg) markedly inhibits TNF production but does not affect serum levels of IL-10, while a high dose of this compound (50 mg/kg) increases LPS-induced IL-10 levels. This chemical (from 0.01 to 100 mg/mL) also increases the biosynthesis of IL-10 by LPS-activated mouse peritoneal macrophages.
In vivo	Methylprednisolone decreases RGC survival in rats with electrophysiologically diagnosed optic neuritis. This compound decreases RGC survival by a nongenomic, calcium-dependent mechanism. Its induced enhancement of RGC degeneration depends on calcium influx through voltage-gated calcium channels. This treatment leads to a significant decrease in the number of ED1-positive cells in both rostral and caudal stumps. It results in a significant reduction in tissue loss in both cord stumps at 2, 4 and 8 week post-injury. This chemical 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. At a dose of 30 mg/kg which has been shown to be effective in improving functional outcomes in rat SCI models, it suppresses TNF-α expression and NF-kB activation. Its inhibition of NF-kB function is likely mediated by the induction of IkB, which traps NF-kB in inactive cytoplasmic complexes.
