  Design and synthesis of 4-alkynyl pyrazoles as inhibitors of PDE4: A practical access via Pd/C–Cu catalysis

  摘要：

  The design and synthesis of 4-alkynyl pyrazole derivatives has led to the identification of new class of PDE4 inhibitors. All these compounds were accessed for the first time via a facile Pd/C-CuI-PPh3 mediated C-C bond forming reaction between an appropriate pyrazole iodide and various terminal alkynes. In vitro PDE4B inhibitory properties and molecular modeling studies of some of the compounds synthesized indicated that 4-alkynyl pyrazole could be a promising template for the discovery of novel PDE4 inhibitors.
