  • PubMed Abstract: 

    PDE4 inhibitors have been identified as therapeutic targets for a variety of conditions, particularly inflammatory diseases. We have serendipitously identified a novel class of phosphodiesterase 4 (PDE4) inhibitor during a study to discover antagonists of the parathyroid hormone receptor. X-ray crystallographic studies of PDE4D2 complexed to four potent inhibitors reveal the atomic details of how they inhibit the enzyme and a notable contrast to another recently reported thiophene-based inhibitor.
