  Isoxazolopyridone derivatives as allosteric metabotropic glutamate receptor 7 antagonists

  摘要：

  This Letter describes the synthesis and evaluation of mGluR7 antagonists in the isoxazolopyridone series. In the course of modi. cation in this class, novel solid support synthesis of the isoxazolopyridone scaffold was developed. Subsequent chemical modi. cation led to the identification of several potent derivatives with improved physicochemical properties compared to a hit compound 1. Among these, 2 showed good oral bioavailability and brain penetrability, suggesting that 2 may be useful for in vivo study to elucidate the role of mGluR7. (C) 2009 Elsevier Ltd.
