CDP-840

Research use only, not for human use.

CDP-840 (CDP840;L-765527) is a potent and selective PDE4 inhibitor with IC50 of 4-45 nM for PDE 4 extracted from tissues or recombinant PDE 4 isoforms expressed in yeast.

CDP-840 (CDP840;L-765527) is a potent and selective PDE4 inhibitor with IC50 of 4-45 nM for PDE 4 extracted from tissues or recombinant PDE 4 isoforms expressed in yeast; shows no effect for PDE-1, 2, 3, 5, and 7 (IC50>100 uM), exhibits no significant selectivity in inhibiting human recombinant isoenzymes PDE-4A, B, C or D and is equally active against the isoenzymes lacking UCR1 (PDE-4B2 and PDE-4D2); causes a dose-dependent reduction of IL-5-induced pleural eosinophilia in rats (ED50=0.03 mg/kg); prevents antigen-induced eosinophilia and bronchoconstriction; orally active.Asthma Phase 2 Discontinued
