General description

Most active and highly stable glucocorticoid. Causes a reduction in cyclin A and Cdk2 activity, and inhibition of G1/S transition in osteoblasts. Inhibits the phosphorylation of retinoblastoma (Rb) protein. Inhibits the expression of inducible but not constitutive nitric oxide synthase in vascular endothelial cells (IC50 = 5 nM). Enhances active cation transport in aortic smooth muscle cells by stimulating the Na+ - K+ pump. Induces apoptosis in human thymocytes.
Most active and highly stable glucocorticoid. Inhibits the expression of inducible but not constitutive nitric oxide synthase in vascular endothelial cells (IC50 = 5 nM). Enhances active cation transport in aortic smooth muscle cells by stimulating the Na+-K+ pump. Has anti-inflammatory and antirheumatic properties. Induces apoptosis in human thymocytes. In general, 500-1000 nM of dexamethasone is sufficient to induce apoptosis following a 6 h incubation at 37°C.
