PDE4B-IN-2 is an orally active and selective PDE4B inhibitor (IC50=15 nM) and exhibits >100-fold selectivity for PDE4B over 4D. PDE4B-IN-2 regulates cAMP in inflammatory cells and inhibits LPS-induced TNF-α production and neutrophil accumulation in mouse lungs. PDE4B-IN-2 reduces microglial and neutrophil activation, and improves behavioral deficits in a traumatic brain injury model in vivo. PDE4B-IN-2 also exhibits antidepressant-like effects.
