Details:

Dexamethasone is an antiinflammatory glucocorticoid that induces the production of phospholipase A2 inhibitory protein (lipocortin).  It also inhibits induction of nitric oxide synthase (IC50=5 nM). Dexamethasone has been shown to cause reduction in cyclin A and Cdk2 activity,  inhibition of G1/S transition in osteoblasts and inhibition of phosphorylation of Rb protein. Dexamethasone has been observed to induce  apoptosis in human thymocytes and eosinophils, but inhibits apoptosis in neutrophils. Dexamethasone is an activator of IDO.
