  Synthesis and structure–activity relationships of N3-pyridylpyrazinones as corticotropin-releasing factor-1 (CRF1) receptor antagonists

  摘要：

  A series of N-3-pyridylpyrazinones was investigated as corticotropin-releasing factor-1 receptor antagonists. It was observed that the binding affinity of analogues containing a pyridyl group was influenced not only by the substitution pattern on the pyridyl group, but also by the pK(a) of the pyridyl nitrogen. Analogues containing a novel 6-(difluoromethoxy)-2,5-dimethylpyridin-3-amine group were among the most potent N-3-pyridylpyrazinones synthesized. The synthesis and SAR of N-3-pyridylpyrazinones is described herein. (C) 2010 Elsevier Ltd. All rights reserved.
