CDP840. A prototype of a novel class of orally active anti-inflammatory phosphodiesterase 4 inhibitors

The discovery, synthesis and biological activity of a series of triarylethane phosphodiesterase 4 inhibitors is described. Structure-activity relationship studies are presented for CDP840 (29), a potent, chiral, selective inhibitor of PDE 4 (IC50/su
