Abstract
The search for novel phosphodiesterase Type 4 (PDE4) inhibitors remains one of the most active fields within the pharmaceutical industry. Recent progress within the clinical development of PDE4 inhibitors has seen two more compounds progress to Phase III development. However, both Ariflo™ (SB-207499) and roflumilast are being developed principally for the treatment of chronic obstructive pulmonary disease (COPD) rather than asthma. This review also highlights the novel structural classes of PDE4 inhibitors disclosed in the past year’s patent applications and the concentration of effort on the identification of selective PDE4D inhibitors.
