  Synthesis of 3-phenylpyrazolo[4,3-b]pyridines via a convenient synthesis of 4-amino-3-arylpyrazoles and SAR of corticotropin-Releasing factor receptor type-1 antagonists

  摘要：

  3-Phenylpyrazolo[4,3-b]pyridines were synthesized via a cyclization of 4-amino-3-phenylpyrazoles 11-13 with ethyl acetoacetate. These compounds were found to be potent CRF1 antagonists. The 2-alkylpyrazolo[4,3-b]pyridines were more polar but less active than the corresponding 1-alkyl-isomers. (C) 2003 Elsevier Ltd. All rights reserved.

  Design and Synthesis of Tricyclic Corticotropin-Releasing Factor-1 Antagonists

  摘要：

  Antagonists of the corticotropin-releasing factor (CRF) neuropeptide should prove to be effective in treating stress and anxiety-related disorders. In an effort to identify antagonists with improved physicochemical properties, new tricyclic CRF, antagonists were designed, synthesized, and tested for biological activity. As a result of studies aimed at establishing a relationship between structure and CRF, binding affinity, NBI 35965 (12a) was identified as a high-affinity antagonist with a pK(i) value of 8.5. Compound 12a proved to be a functional CRF, antagonist with pIC(50) values of 7.1 and 6.9 in the in vitro CRF-stimulated cAMP accumulation and ACTH production assays, respectively, and 12a also reduced CRF or stress induced ACTH production in vivo.
