CDP 840 is a selective phosphodiesterase type IV (PDE4) inhibitor with an IC50 value of 0.007 µM . PDE4 is most abundantly distributed in inflammatory cells such as monocytes and macrophages . PDE4 is a high-affinity cAMP-selective isozyme. It was found that PDE4 was in almost all cell types in asthma pathogenesis . CD P840 showed a potent inhibition against PDE4 with IC50 values ranging from 2-30 nM to different isoenzymes of PDE4. There are four expressed PDE4 isoenzymes in baculovirus cells, i.e. PDE4A, PDE4B, PDE4C and PDE4D. Except for PDE4C2, CDP 840 did not exhibit isoform selectivity of PDE4. CD P840 exhibited a hill number of about 1.0 against all four PDE4 isoenzymes. For all four PDE4 isoenzymes, CDP 840 acted as a simple competitive inhibitor . In vivo, CDP 840 (30 mg/kg) increased cAMP by 145% in the hippocampus and by 112% in the prefrontal cortex of male Sprague-Dawley rats. CDP 840 at doses of 10 and 30 mg/kg increased the phosphorylation of cAMP response element binding protein (pCREB) in the hippocampus (by 36 and 55%, respectively) and in the prefrontal cortex (by 32 and 60%, respectively). But these doses did not affect the expression of the cAMP response element binding protein (CREB). Repeated treatment with CDP 840 at a dose of 30 mg/kg increased the cell proliferation in rat hippocampus, but these cells were not survival .
