A 33 New
Potent and selective PDE4B inhibitor (IC50 = 15 nM); exhibits >100-fold selectivity for PDE4B over 4D. Regulates cAMP in inflammatory cells. Inhibits LPS-induced TNF-α production and neutrophil accumulation in mouse lungs. Reduces microglial and neutrophil activation, and improves behavioral deficits in a traumatic brain injury model in vivo. Also exhibits antidepressant-like effects. Orally bioavailable.
