A cell permeable, potent, and selective oxime PDE4D inhibitor (IC50=0.67uM) which displays much reduced activities toward other PDE4 isoforms. It is shown to cause a significant 40% increase in extracellular cAMP in the hippocampus of freely moving rats in vivo at 100uM, but has no effect on Ab levels. This compound elicits cognitive enhancement in vivo at the optimum dose of 0.003mg/kg in both mice and rat models, and unlike rolipram, does not cause emesis-like behavior in rodents.
