  Discovery of selective PDE4B inhibitors

  摘要：

  In this study the first PDE4B selective inhibitor is described. Optimization of lead 2-arylpyrimidine derivatives afforded a series of potent PDE4B inhibitors with >100-fold selectivity over the PDE4D isozyme. With a good pharmacokinetic profile, a selected compound exhibited potent anti-inflammatory effects in vivo and showed less emesis compared with Cilomilast. (C) 2009 Elsevier Ltd.
